2010 Jaguar XFR

The enhanced exterior styling of the Jaguar XFR moves those sporting credentials on even further, to deliver the ultimate expression of Jaguar's new saloon car design language - carrying a number of visual design cues that are intrinsic to Jaguar's 'R' car philosophy. Its unique front-end design has a larger lower grille with new black-finished mesh, plus chrome outboard air intakes. The upper mesh grille retains XF's bright finish, while the bonnet carries distinctive louvres, like those on the XKR sports car.

The Jaguar XFR also features bold new sill extensions, while the rear bumper adds a unique body-coloured lower valance panel incorporating the 'R' signature of four large, bright-finished tail pipes. The new bootlid spoiler has a significant aerodynamic effect. Developed in conjunction with the new front bumper design, it further improves the Jaguar XFR's front/rear lift balance, and therefore its high-speed stability. A new exterior mirror design also offers aerodynamic improvements, plus improved functionality with its LED side repeaters.

The Jaguar XFR's sporting character is clearly apparent in the 20-inch Nevis alloy wheels. It is the only car in its class to offer this size of wheel as standard specification. Those twin-seven-spoke wheels bear the wording 'Jaguar Supercharged' embossed around their centres, and are wrapped tightly around silver-grey brake callipers, which carry the evocative 'R' logo. The R badge also appears on the right-hand side of the boot lid drop panel, to complete the XFR's external visual identity.

The new Jaguar XFR is offered with a select palette of just eight exterior colours: Ultimate Black, Indigo, Liquid Silver, Lunar Grey, Porcelain, Botanical Green, Kyanite Blue and Salsa. All except Salsa and Porcelain are metallic colours and, within the XF range, Salsa and Kyanite Blue are unique to Jaguar XFR. For each colour - as across the entire XF range - Jaguar suggests a 'Designer's Choice' of the leather trim colours that best complement each body colour and the Warm Charcoal upper facia that is standard on every Jaguar XFR.

The interior design theme is modern and individual. The cabin environment is uniquely Jaguar and in the XFR more details hint at the car's performance. A full soft grain leather interior is standard, with four colour choices - Warm Charcoal, Warm Charcoal/Red Zone, Warm Charcoal/London Tan, and Ivory. A new Dark Oak veneer is the standard finish for the Jaguar XFR's wood-trimmed areas. New 18x14-way adjustable sports seats have electrically adjustable squab bolsters for significantly improved support at higher cornering speeds. Each Jaguar XFR seat has the 'R' logo embossed on its squab and the front seats have leather seat-back map pockets.

The fascia introduces a unique, dark mesh aluminium finish, and another discreet 'R' badge on the passenger side of the instrument panel. The speedometer and tachometer have the unique sporting signature of red dial pointers, and carry the 'Supercharged' motif. And at start-up, the 'R' logo appears on the Touch-screen as part of the XFR 'driver handshake' sequence.

The most advanced Jaguar V8 engines ever

The supercharged 5.0-litre V8 that powers the new XFR is Jaguar's new flagship engine, but it is only half of the petrol engine story - a naturally-aspirated version of the all-new engine brings additional advanced technologies and performance to other models in the XF range.

Light, robust and very strong

The all-new 5.0-litre V8 petrol engines are built around a stiff, all-new, aluminium block with cast-in iron liners and cross-bolted main bearing caps to reduce noise, vibration and harshness. For the first time at Jaguar the blocks are high-pressure die-cast, providing a superior finish and greater dimensional accuracy. The engines use aluminium heads, with four valves per cylinder and strong, spheroidal-graphite cast-iron crankshafts and forged steel connecting rods. The cylinder heads for the first time are specified with a secondary (recycled) aluminium alloy, reducing the environmental impact of manufacturing the new engine.

The new 5.0-litre V8 engines are more compact than their predecessors. Overall engine length has been reduced by 24mm by relocation of the oil pump within the engine architecture. This length reduction improves engine bay packaging in support of enhanced safety cell performance while ensuring overall engine weight is virtually unchanged.

Direct injection - power with economy

One of the key features of the new petrol engines is an industry-first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar directly to the cylinder. This substantially contributes to improved low-speed, dynamic response. The positioning of the injectors ensures fuel is precisely delivered to the centre of the combustion chamber, maximising air-fuel mixing, and improving combustion control. Fuel is delivered via twin, high-pressure fuel pumps that are driven via an auxiliary shaft in the all-new engine block.

The charge-cooling effects of the direct-injection fuel system have allowed the compression ratio of the naturally aspirated engine to be raised to 11.5:1, further improving the engine economy. The supercharged engine also benefits from an increase from 9.1:1 on the previous 4.2-litre version to 9.5:1.

During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and substantially reduced emissions.

Torque-actuated Variable Camshaft Timing improves efficiency

A new type of variable camshaft timing system (VCT) introduces another new technology. The four VCT units are activated by the positive and negative torques generated by opening and closing the intake and exhaust valves, instead of by oil pressure. This has allowed the engine oil pump to be reduced in size, saving energy and reducing fuel consumption.

VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimised by the engine control unit for torque, power and economy at every point in the engine's speed range.

The response rate of the new VCT units is up to three times faster than before, with actuation rates in excess of 150 degrees per second. This delivers a more immediate engine response to the driver's demand.

The naturally aspirated engine is also equipped with camshaft profile switching (CPS) on the inlet camshaft. Depending on the engine's running conditions and the demands of the driver, the CPS will switch between a profile that is ideal for low-speed driving, and another which gives increased valve lift for high performance.

Variable Inlet Manifold optimises torque through the rev range

A new variable inlet manifold (VIM) can vary the length of its eight inlet tracts to optimise power and torque throughout the rev range on the naturally aspirated engine. Vacuum-operated actuators open valves to select a longer, 680mm inlet tract at low revs, increasing the rate of both the airflow and the engine torque. As the revs climb beyond 4700rpm, the actuators select a shorter, 350mm path allowing a greater volume of air into the engine to optimise engine power. The actuator position is optimised by the engine control unit for improved torque throughout the engine speed range.

Improved efficiency through new technology

Minimising internal friction is key to improving fuel consumption and CO2 emissions, and as such was a key aim when it came to the design of the engines. As a result, the new Jaguar AJ-V8 Gen III engines achieve another best in class, setting a new industry benchmark for cranktrain efficiency.

All engine bearings were the subject of an extensive optimisation programme, reducing friction without compromising reliability. Diamond-Like Carbon Coating (DLC) has been used to reduce friction on the fuel pump tappets and a solid film lubricant has been used to coat the piston skirts.

Jaguar has developed a unique, intelligent oil-pump pressure relief valve (PRV) which senses oil pressure deep in the engine's oil galleries to control the oil pump delivery. As a result, oil pump frictional losses are reduced during the warm-up period. New engine oil has a lower viscosity, contributing to an extension in service intervals from 10,000 miles to 15,000 miles or 12 months. Both V8 engines are now fitted with an electronic oil level sensor feature for added peace of mind.

Unique, Jaguar sound quality

Sound quality is a key characteristic of all Jaguars and is one particular aspect that customers relish. With that in mind, Jaguar engineers have deliberately accentuated the acoustic feedback into the cabin in order to further increase driving pleasure.

The Jaguar XFR has received special attention to deliver the required V8 intake sound character commonly absent on supercharged engines. Intake manifold pressure pulsations are fed into an acoustic filter at the rear of the engine that is tuned to "tenor C", with the output from the filter ducted into the cabin. The filter is controlled by the engine management system which allows the acoustics to enter the cabin only under certain conditions, such as when the engine is accelerating hard, thus maintaining the desired sound quality at all times.

New supercharger optimises power

A sixth-generation, twin vortex system (TVS) supercharger is fitted to the Jaguar XFR's 510PS engine. It is a compact Roots-type unit, feeding air through twin intercoolers, which in turn are water-cooled by their own discreet cooling circuit. The high helix rotor design improves the supercharger thermodynamic efficiency by 16 percent. It also improves noise quality to the point where the unit is now virtually inaudible (making supercharger whine a thing of the past). The intercoolers reduce the temperature of the pressurised intake-air and so optimise power and efficiency.

The new air intake has been radically redesigned compared to the previous V8. The intake air path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air is delivered through twin air boxes, which reduce flow loss and further increase efficiency.

Mechanically, the new supercharger and its intercoolers are efficiently packaged in the 'V' of the engine to deliver a low overall engine height in support of pedestrian safety requirements.

Advanced six-speed transmissions

The all-new 5.0-litre AJ-V8 Gen III and the 3.0-litre diesel AJ-V6 D Gen III engines transmit power through an enhanced version of Jaguar's acclaimed ZF 6HP28 electronically controlled, six-speed transmission. Additional clutch plates and an uprated torque converter have been added for the supercharged V8 to facilitate the extra power.

The transmission has a fully-adaptive shift system which delivers extremely smooth gear changes and optimises performance and economy at all times. The Jaguar Sequential Shift™ suffers no torque interrupt resulting in a smoother more powerful shift feel and an almost instantaneous shift from the time the driver touches the shift paddle to the completion of the shift event. It also continually adapts to suit driving style, which can vary from sporting to more economical. The 'mechatronic' control module incorporated inside the transmission includes the software for the semi-automatic Jaguar Sequential Shift™ function, selected when the driver operates either of the two steering-wheel paddles.

The high levels of torque produced by the new engines make it possible for the torque converter lock-up feature of the transmission to be used even at low speeds, without slip. This approach provides competitive fuel consumption, contributing to the official combined fuel economy of 22.5mpg (12.5l/100km) in the Jaguar XFR and 25.4mpg (11.1l/100km) in the naturally aspirated V8-powered XF. The advanced design of the transmission includes a torsional damper to absorb firing impulses from the engine, further smoothing the driveline. The transmission is designed to be maintenance-free and the fluid is 'filled-for-life.'

Driving Dynamics

The headline advances made by Jaguar's new engines are hugely significant and impressive. They take Jaguar's philosophy of 'intelligent power' to another new level and that means instant responses, seamless power and smooth, refined performance with comparable fuel economy and better emissions - all thanks to intelligent use of the most advanced technologies. And, of course, in Jaguar XFR guise, it makes for the quickest XF yet.

In line with the additional performance, Jaguar XFR adopts the largest brakes fitted to the XF range, with 380mm diameter internally ventilated front discs. Jaguar XFR's unique 20-inch wheels and tyres were specifically chosen to enhance the dynamic character of the car, and in particular to optimise wet weather grip.

Jaguar's Emergency Brake Assist is standard on XF and Adaptive Cruise Control (ACC) is now available as an option all models. Advanced Emergency Brake Assist is a new attribute of the ACC system on the new 3.0 V6 diesel and 5.0 V8 petrol models; it uses the ACC radar to calculate distance from and speed of approach to the vehicle ahead and pre-charges the brake-line pressure to minimise impact speed if a collision is predicted - as well as giving an audible warning to the driver.

To improve handling and steering responses, the Jaguar XFR is fitted with a 'fast ratio' steering rack, and additionally benefits from the further improved front-to-rear aerodynamic balance offered by a new boot lid spoiler and deeper front bumper. This is a significant gain as XF's lift balance was already best in class, and its low overall aerodynamic drag coefficient of only 0.29Cd contributes to both low wind noise and inherent high-speed stability.

The XF's body shell is already extremely stiff - in fact the stiffest in its class. This is key to the XF delivering superb ride and handling based on taut body control and precise, responsive steering. The bodyshell for the new MY 2010 Jaguar XF is even stiffer, thanks to a new rear subframe and the adoption of a boot cross-brace that was previously only fitted to the XF SV8 supercharged model.

Latest computer-controlled suspension and differential

The biggest changes in chassis dynamics for the Jaguar XFR, however, come from two new advanced technologies, Adaptive Dynamics and Active Differential Control, which are both incorporated as standard.

Active Differential Control (ADC) with traction-only functionality and handling functionality is an electronically controlled alternative to the traditional, wholly mechanical differential, offering more subtle control strategies.

ADC can vary its locking torque (and therefore the proportion of torque to each driven rear wheel) depending on surface conditions and power applied. Its control strategies optimise traction at each wheel, improving acceleration on low-grip surfaces while also enhancing cornering ability.

ADC has no adverse effect on either refinement or stability - where the traditional, mechanical differential can compromise stability under hard applications of power, demanding more corrective input from the driver. Whereas a mechanical differential is a permanently active part of the drivetrain, the Jaguar XFR's new ADC system is switched off when not required, so does not create undesirable understeer and creates no issues with NVH at lower speeds.

The differential is operated by an internal electric motor and 'ball-and-ramp' mechanism, and contains a multiplate clutch, which transmits or 'vectors' torque to the wheel with most grip. The multi-plate clutch assembly is designed to prevent excessive differential slip, but differs fundamentally from a conventional traction control which uses the brakes to counteract slip after it has occurred.

Continuously variable damping

Adaptive Dynamics, which replaces Jaguar's proven Computer Active Technology Suspension (CATS) on the Jaguar XFR, is a highly sophisticated active damping system which automatically adjusts suspension damper settings to suit both road conditions and the way in which the car is being driven. By removing the need for compromise between a fixed, softer setting for ride comfort and a fixed, firmer setting for tauter body control and handling, Adaptive Dynamics allows the balance between ride and handling to be optimised whatever the circumstances. Unlike earlier systems with only a small number of steps in the damper settings, it offers a progressively variable damping strategy between wide extremes, to deliver a comfortable but sporty ride with impressively sharp handling.

The three primary functions of Adaptive Dynamics are to control vertical movement, roll rate and pitch rate of the body. It does this by analysing induced body motions one hundred times a second, and setting each damper to an appropriate level in order to maintain a constant and level body attitude, thereby optimising control without compromising ride. Also one hundred times a second, it predicts the roll-rate due to steering inputs, and selectively increases damping forces to reduce that roll-rate - improving feel and driver confidence - as well as analysing fore and aft pitch rate due to throttle and braking inputs, and again varies damping forces to reduce pitch, further improving comfort and control.

Additionally, Adaptive Dynamics improves ride by monitoring wheel position 500 times a second and automatically increasing damping rate as the suspension approaches the limits of its travel. Similarly, it controls wheel 'hop' by varying damping to move any wheel out of a natural bouncing frequency, again benefiting ride comfort, handling, and even grip.

Jaguar XFR also features Handling Functionality, which is unique in this class. In conjunction with the DSC Off option and JaguarDrive Control™ with Dynamic Mode, this supplements all the advantages of Traction Only Functionality with a number of more driver-focused dynamic characteristics. When selected, Dynamic Mode (which is also standard on the new naturally aspirated 5.0-litre V8 petrol and new 3.0-litre V6 diesel models) modifies the throttle, stability and transmission parameters, and on Jaguar XFR only it also modifies the Adaptive Dynamics responses. The combination of ADC and Dynamic mode with DSC Off allows controllable power-on oversteer, and improves off-throttle stability, allowing quicker, more spirited cornering. It can also improve stability in situations such as an emergency lane-change manoeuvre at high speed and, in combination with DSC, reduce the brake interventions which the more enthusiastic driver might see as intrusive.

So, working with DSC, the TCS traction control system and ABS braking function, ADC can significantly improve overall vehicle performance, and provide even more precise driving feel. Together with its very high performance potential, that is what defines the new Jaguar XFR as a perfect home for Jaguar's 'R' philosophy, and the sportiest of all XF models.

2010 Jaguar XKR

The new Jaguar XKR is a sophisticated grand tourer with the heart of a true sports car, combining effortless high-performance and state-of-the-art V8 powertrains with a new level of advanced technologies, intuitive control and Jaguar's superbly crafted, new-fashioned luxury interiors. The range comprises naturally aspirated XK and supercharged Jaguar XKR models, available in 2+2 coupe or convertible body styles.

All-new AJ-V8 Gen III 5.0-litre direct-injection engines bring significant improvements in power and torque and they do so without compromising fuel economy and emissions. In both respects, every model in the new XK range, in spite of such large performance and flexibility gains across the board, is comparable to their predecessors.

The impressive fuel economy for such powerful cars is attributable to the combination of the XK range's lowest-in-class weight and the all-new AJ-V8 Gen III engines. As well as the intrinsic advantages of the engines' light weight, these advanced all-aluminium four-cam power units have a number of features that deliver power with very high efficiency, including spray-guided direct injection (SGDI), which improves performance and economy, and dual independent variable cam timing (DIVCT), which benefits performance and economy, while also reducing emissions.

The simplified and logical model range for the new XK comprises three clear choices - XK, XK Portfolio and supercharged Jaguar XKR. Each has its own specific choices of trim, colour and fine detail, but every one has the same underlying sporting character and clear emphasis on efficient performance, luxury and craftsmanship. Beyond that, the XK vehicle personalisation programme also offers an extensive range of accessories that allow the customer to add further bespoke touches, both inside and out.

Performance on a new level

In naturally aspirated form, the new AJ-V8 Gen III 5.0-litre engine delivers 385PS (SAE) and 380lb ft (515Nm) of torque - respectively 26 and 23 percent more than its 4.2-litre predecessor. The Jaguar XKR's supercharged 5.0-litre version delivers a mighty 510PS (510bhp SAE) and 461lb ft (625Nm) of torque - improvements of 23 and 12 percent respectively over the supercharged 4.2-litre engine.

On the road, while maximum speed remains under electronic control at 155mph (250kph), these power and torque gains allied to the lightweight aluminium body architecture of the XK dramatically improve acceleration times. For the naturally aspirated XK, 0-60mph is reduced to 5.2 seconds from 5.9 seconds (and 0-100kph from 6.2 to 5.5 seconds); for the supercharged Jaguar XKR, 0-60mph is reduced to 4.6 seconds from 4.9 (and 0-100kph to 4.8 seconds from 5.2).

The supercharged Jaguar XKR is also impressively efficient, with combined fuel economy of 23.0mpg and a CO2 rating of 292g/km - an improvement over the previous Jaguar XKR - and 16 and 17 percent better, respectively, than the equivalent figures for the BMW M6.

Crucially, however, the naturally aspirated XK also continues to better its closest rivals on economy and CO2 ratings, with an average consumption of 25.2mpg and a CO2 figure of 264g/km - seven percent better than the equivalent figures for the Mercedes-Benz SL500 thanks to its fuel efficient engine and significantly lower kerb weight: 1660kg compared to the SL500's 1845kg.

Exterior design

Visible changes on the new XK and XKR reflect the significant changes under the skin. Carefully revised exteriors take the seductive, elegant lines that define Jaguar's new design language and interpret them for a beautiful 2+2 sports car whose shape is even more taut, powerful and athletic. Evoking the essence of performance long before it moves, the new XK family shape is unmistakably 'new-school' sporting Jaguar: wholly contemporary, finely sculpted, efficiently packaged and precisely detailed.

The exterior changes for the naturally aspirated XK models and the supercharged Jaguar XKR are highlighted by a distinctive and purposeful new front end design, new LED rear lights and a new lower rear body valance. New LED rear light clusters incorporating fog lamps plus twin reversing lamps (rather than the previous single lamp units) give every new XK a unique 'night time signature', while LED technology is also included in the integrated side repeater and approach lamps in the new exterior mirrors. Every new XK also features revised body-coloured side power vents.

Beyond the shared changes, subtle differences in detail distinguish each of the three models in the new XK range. All display purposeful front bumper features with stylish, chrome-detailed inserts and further chrome detailing to the upper mesh grille. The Jaguar XKR is set apart by also featuring chrome on its lower mesh grille - which is finished in black on the XK and XK Portfolio models. All models now feature chrome detailing on window surrounds and rear signature blade, and in addition the Jaguar XKR comes with a new lower rear valance that is finished in body colour and a revised tailpipe design, further emphasising its sporting performance.

Interior design

Contemporary, sporting luxury, exceptional quality of craftsmanship, and Jaguar's renowned attention to detail are the keynotes of the new XK range's enhanced interiors. The cabin is clean, elegant and spacious, and remains entirely in harmony with the sporting character of the revised exterior.

The luxury character of the new XK and XKR, however, is guaranteed, regardless of the customer's choice of body style - hard-topped coupe or fabric-roofed convertible. Both benefit from the inherent strength of Jaguar's lightweight aluminium architecture, which means that as well as being the lightest body structure in its class, the body shells also have the highest torsional strength. And that exceptional rigidity, with or without a fixed roof, means creak and rattle-free refinement, even on unforgiving surfaces.

Beyond that, the convertible's triple-lined fabric roof gives a level of fit and stability, even at very high speeds, that minimises wind noise and other road noise and includes a luxurious interior finish almost indistinguishable from a fixed roof. In addition, XK Portfolio and XKR models feature luxurious Jaguar Suedecloth headlinings as standard.

The folding roof can be powered up or down at the touch of a button in less than 18 seconds. And when it is lowered, the convertible's flush-folding roof retracts completely into the bodywork behind the rear seats, under a smooth cover that retains the elegant, sporting lines of the car. A roll-over protection system, which remains hidden unless it is needed, deploys instantaneously as necessary to provide occupants with the highest levels of protection in the event of an incident.

For both coupé and convertible, the latest feature enhancements are showcased by the JaguarDrive Selector™, which is neatly and elegantly packaged in the centre console. The welcome to the car is also enhanced by new, bright treadplate inserts. Many of the other changes emphasise high levels of Jaguar craftsmanship with new jewel-like touches. The three-spoke steering wheel now has a leather-wrapped lower spoke, and Jaguar's striking 'growler' badge. The new Jaguar XKR's instruments further emphasise its performance character with red pointers, while all models adopt a new white illumination for their instruments.

New heated and cooled front seats are standard equipment on the new XK Portfolio and on XKR with the optional R Performance interior (dependent on market), and available as an option on the XK. The XK features 10-way seat adjustability for both driver and passenger seats, with heating and memory functions as standard - while the Jaguar XKR seats have similar functions but with the unique R seat style. The XK Portfolio and XKR with the optional R Performance interior have 16-way adjustable seats with heating and memory functions, adjustable side bolsters and new cooled seats as standard.

The door casings are even more luxuriously crafted than before, with saddle-stitched lines and a new interlayer to give a softer touch to the top shoulder of the casing. The leather door pulls also introduce

twin-needle stitching and a soft-feel interlayer. In each door, the modified seat switch pack now includes single-piece chrome 'highlight' switches.

There is a wide choice of interior colour options, including a new combination for the XK Portfolio and XKR of Ivory seating with Oyster upper cabin trim and Oyster carpets. Bond grain leather is standard on the new XK interior, and an even higher quality soft-grain leather with contrast stitching is standard in the XK Portfolio and the new R Performance Jaguar XKR.

Real wood veneers remain an important part of Jaguar craftsmanship and now include a new Rich Oak veneer option alongside the classic Burr Walnut for all three models. The new XK Portfolio also offers the choice of an Ebony veneer, while the Jaguar XKR offers its own unique alternative in Dark Oak. A Knurled Aluminium veneer is also available on XK and XK Portfolio, while Dark Mesh Aluminium is available on XKR.

Industry-leading lightweight body architecture

Globally recognised as one of the key elements in Jaguar's intelligent use of advanced technologies, the XK's industry-leading lightweight architecture constructs the entire body shell (the internal chassis structure and external body panels) from a combination of pressed, cast and extruded aluminium alloy components. These are riveted and bonded together using techniques originally developed in the aerospace industry and adapted for automotive use by Jaguar.

The result is a body shell with a depth of quality that is rooted in the highest structural integrity. It is also the lightest shell in its class by a significant margin and the most torsionally stiff. That all-round strength, rigidity and lightness underpin many aspects of the XK's excellence, from fuel-efficient performance to its inherent safety, durability and refinement - and, of course, its precise chassis dynamics.

The most advanced Jaguar V8 engines ever

Since the first XK was launched in 1948, generations of powerful yet refined engines have played a crucial role in establishing the unique character and pedigree of Jaguar cars. Now, the new 5.0-litre V8 direct-injection engines continue that tradition, delivering increased power and torque with reduced emissions and impressive fuel economy. Available in two versions - the supercharged 510PS and naturally aspirated 385PS - the new AJ-V8 Gen III engines exemplify Jaguar's reputation for innovation and engineering excellence.

The results are clear to see. Performance has been increased by 29 percent and 23 percent (87 and 94PS) on the naturally aspirated and supercharged engines respectively, yet both meet EU5 and US ULEV2 emissions regulations. Despite the significant increases in power, both have better emissions and comparable fuel economy to the previous 4.2-litre units.

Both new AJ-V8 Gen III petrol engines are state-of-the-art in every sense. The technical features have been engineered to deliver unparalleled efficiency, refinement, power and torque for which Jaguar is famous, combined with the lowest possible emissions. Low-speed torque characteristics and throttle response are world-class, while the supercharged version is one of the most economical 5.0-litre V8 engine available.

Light, robust and very strong

The new AJ-V8 engines are built around a stiff, all-new, aluminium block with cast-in iron liners and cross-bolted main bearing caps to reduce noise, vibration and harshness. The blocks are high pressure die-cast, providing a superior finish and greater dimensional accuracy. The engines use aluminium heads, with four valves per cylinder and spheroidal-graphite cast-iron crankshafts and forged steel connecting rods. The cylinder heads for the first time are specified with a secondary (recycled) aluminium alloy thus reducing the environmental impact of manufacturing the new engine.

The new 5.0-litre direct injection petrol engines are more compact than their predecessors. Overall engine length has been reduced by 24mm by relocation of the oil pump within the engine architecture. This length reduction - apparently a small amount - improves engine bay packaging in support of enhanced safety cell performance while ensuring overall engine weight is virtually unchanged.

New supercharger optimises power

A sixth-generation, twin vortex system supercharger is fitted to the Jaguar XKR's 510PS engine. It is a compact Roots-type unit, feeding air through twin intercoolers, which in turn are water-cooled by their own discreet cooling circuit. The high helix rotor design improves the supercharger thermodynamic efficiency by 16 percent over its predecessor. It also improves noise quality to the point where the unit is now virtually inaudible (making supercharger whine a thing of the past). The intercoolers reduce the temperature of the pressurised intake-air and so optimise power and efficiency.

The new air intake has been radically redesigned compared to the previous V8. The intake air path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air is delivered through twin air boxes, which reduce flow loss and further increase efficiency.

Mechanically, the new supercharger and its intercoolers are efficiently packaged in the 'V' of the engine to deliver a lower overall engine height in support of pedestrian safety requirements.

Direct injection - power with economy

One of the key features of the new petrol engines is an industry-first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar directly to the cylinder. This substantially contributes to improved low-speed, dynamic response. The positioning of the injectors ensures fuel is precisely delivered to the centre of the combustion chamber, maximising air-fuel mixing and improving combustion control. Fuel is delivered via twin, high-pressure fuel pumps that are driven via auxiliary shaft in the all-new engine block.

The charge cooling effects of the direct-injection fuel system have allowed the compression ratio of the naturally aspirated engine to be raised to 11.5:1, further optimising the engine economy. The supercharged engine also benefits from a compression ratio increase to 9.5:1 from 9.0:1 in the previous 4.2-litre.

During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and emissions reduction.

Torque-actuated variable-camshaft timing improves efficiency

A new type of variable camshaft timing (VCT) system introduces another new technology. The four VCT units are activated by the positive and negative torques generated by opening and closing the intake and exhaust valves, instead of by oil pressure. This has allowed the engine oil pump to be reduced in size, saving energy and improving fuel consumption.

VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimised by the engine control unit for torque, power and economy at every point in the engine's speed range.

The new VCT units are capable of a response rate up to three times faster than in previous Jaguar engines, with actuation rates in excess of 150 degrees per second. This delivers a more immediate engine response to the driver's demand for power.

The naturally aspirated engine is also equipped with camshaft profile switching (CPS) on the inlet camshaft. Depending on the engine's running conditions and the demands of the driver, the CPS will switch between a profile that is ideal for low-speed driving and another which gives increased valve lift for high performance.

Hydraulically-actuated two-piece tappets switch between profiles on the tri-lobe camshaft altering both the lift and duration. The cam lobe profile selected for lower engine speeds has a duration of 214° and lifts the valves 5.5mm. This optimises gas velocity for improved low-speed torque and reduces valvetrain friction for improved fuel economy. For high-speed driving, CPS switches to a cam lobe with a duration of 250° and valve-lift of 10.5mm, allowing greater air flow for high power. Switching is activated at 2800rpm at high load, ranging to 4500rpm at light load conditions.

Variable Inlet Manifold optimises torque through the rev range

A new variable inlet manifold (VIM) on the naturally aspirated engine can vary the length of its eight inlet tracts to optimise power and torque throughout the rev range. Vacuum-operated actuators open valves to select a longer, 680mm, inlet tract at low revs, increasing the rate of both the airflow and the engine torque. As the revs climb beyond 4700rpm, the actuators select a shorter, 350mm path allowing a greater volume of air into the engine to optimise power. The actuator position is monitored by the engine control unit to improve torque throughout the engine speed range.

Reverse cooling turns up the heat

Every component in both V8 engines has been optimised for efficiency, performance, low-end torque and reliability. An innovative reverse-flow cooling system design has been employed to deliver thermodynamic and friction improvements. The reverse-flow cooling system pumps coolant through the cylinder heads before it flows through the block and returns to the radiator. The resulting cooler cylinder heads allow more optimum, knock-free, ignition timings.

In addition, the 22kW oil-to-water heat exchanger, packaged at the core of the engine, transfers heat from the coolant to the lubricating oil during warm up, bringing the oil up to operating temperature 14 percent faster than the cooling system used in the 4.2-litre V8. This improves fuel consumption in the crucial engine warm-up period by approximately one percent - again a small amount, but part of a package of efficiencies.

Reducing friction - something for nothing

Minimising internal friction is key to improving fuel consumption and CO2 emissions, and as such was a key aim when it came to the design of the engines. As a result, the new Jaguar AJ-V8 Gen III engines achieve another best in class, setting a new industry benchmark for cranktrain efficiency.

All engine bearings were engineered for reduced friction without compromising reliability. Diamond-Like Carbon Coating (DLC) has been used to reduce friction on the fuel pump tappets and a solid film lubricant has been used to coat the piston skirts. New engine oil has a lower viscosity, contributing to an extension in

service intervals from 10,000 miles to 15,000 miles (or 12 months). Both V8 engines are now fitted with an electronic oil-level indicator for added peace of mind.

Unique, Jaguar sound quality

Sound quality is a key characteristic of all Jaguars and is one particular aspect that customers relish. With that in mind, Jaguar engineers have accentuated the acoustic feedback into the cabin in order to further enhance the driving pleasure.

The XK's exhaust 'sound track' has been enhanced to provide a deeper and more powerful character that matches the increase in torque at low revs from the new engine. At higher engine speeds the intake acoustic feedback system combines with the exhaust system to provide more of that unique Jaguar sound quality character.

In addition to the fully active exhaust system in which valves open to provide a more rewarding note, the new XKR has been engineered to provide an intake feedback system to enhance the V8 sound character commonly absent on supercharged engines. Intake manifold pressure pulsations are fed into an acoustic filter at the rear of the engine that is tuned to provide an edgy sports car 'crescendo' at high revs. The filter is controlled by the engine management system, which only allows the sound to enter the cabin under the appropriate driving conditions.

The new intake feedback system combined with the fully active exhaust system provides the most exhilarating aural experience yet delivered on a Jaguar.

Uprated six-speed transmission handles extra power

Any transmission is a major factor in delivering the performance that drivers desire, while integrating with the engine to optimise emissions and fuel consumption. Jaguar's acclaimed electronically controlled, six-speed ZF 6HP28 transmission offers an unparalleled combination of driver control matched to virtually undetectable gearshifts. With control either from steering wheel-mounted paddles or full automatic mode via the JaguarDrive Selector™, the new XK range delivers exhilarating performance.The supercharged V8 engine with 510PS and 625Nm of torque transmits power through an uprated version of the ZF 6HP28, additional clutch plates and an uprated torque converter having been added to the transmission to accommodate the extra power.

The transmission has a fully-adaptive shift system which delivers seamless gearshifts and balances performance and economy at all times. It also continually adapts to suit driving style, which can vary from sporting to more economical. Jaguar Sequential Shift™ suffers no torque interrupt, resulting in a smoother more powerful shift feel, and an almost instantaneous shift from the time the driver touches the shift paddle to the completion of the shift event.

The high levels of torque produced by the new engines make it possible for the torque converter lock-up feature of the transmission to function at low speeds, without slip. This approach provides an additional fuel consumption benefit, contributing to the official combined fuel economy of 23.0mpg (12.3 l/100km) in the Jaguar XKR. The advanced design of the transmission also includes a torsional damper to absorb firing impulses from the engine, further smoothing the driveline. The transmission is designed to be maintenance-free with 'filled-for-life' fluid.

Active Differential Control for optimum grip in Jaguar XKR

Another first for Jaguar is the new Active Differential Control (ADC), the final stage of the supercharged V8 driveline. Designed to give improved traction and dynamic stability, the electronically controlled differential continuously adapts to both the driver's demands and the amount of grip available at each individual wheel.

Operated by an internal electric motor and 'ball-and-ramp' mechanism, the differential contains a multiplate clutch which transmits or 'vectors' torque to the wheel with most grip and therefore maximises the car's traction. The multi-plate clutch assembly is designed to prevent excessive differential slip, but differs fundamentally from a conventional traction control system, which uses the brakes to counteract differential slip, after it has occurred.

New JaguarDrive Selector™ completes the package

For the first time, the new XK range introduces the innovative JaguarDrive Selector™ as its transmission control interface. First seen on the Jaguar XF saloon, the JaguarDrive Selector™ features a rotary shift control which rises into the driver's hand as the car is started, to give intuitive, ergonomically efficient transmission control from a neat, space-efficient interface.

The selector is, in fact, much more than just an unobtrusive yet completely practical solution to selecting an automatic gear mode. It also imbues the car with a strong driver 'handshake' - get into an XK and the start button in front of the JaguarDrive Selector™ pulses red, like a heartbeat; press this button to start the engine and the cast alloy JaguarDrive Selector™ rises into the palm of your hand.

From there, automatic transmission functions are selected simply by turning the control with the fingertips. As an example, Drive to Drive Sport selection is accomplished with a simple push and turn action. Returning from S to D, the rotary control operates with spring-assistance, which eliminates the need to pull the Selector. It couldn't be simpler. And when the engine is stopped, the JaguarDrive Selector™ returns automatically to its Park position.

Safety

As well as the convertible's hidden, automatic roll-over protection, every car in the new XK range features Jaguar's pedestrian deployable bonnet system (not fitted to Federal market cars). In the event of a collision with a pedestrian, the system raises the bonnet by 170mm in just 30 milliseconds to provide a clear space between the surface of the bonnet and the hard points underneath, to reduce the severity of injuries - particularly those to the head - while still allowing the new XK low bonnet line. An energy-absorbing bumper system also helps minimise lower leg injuries to pedestrians.

Jaguar's Emergency Brake Assist is standard on the new XK and Advanced Emergency Brake Assist is fitted to all models with Adaptive Cruise Control (ACC). Advanced Emergency Brake Assist uses the ACC radar to calculate distance from and speed of approach to the vehicle ahead and pre-charges the brake-line pressure to minimise impact speed if a collision is predicted - with an audible warning to the driver.

Every model in the new XK range includes front, side and thorax airbags, incorporating new technology which reduces the load on the occupant's body if the front airbag is deployed. Jaguar's Adaptive Restraint Technology System checks for seat occupation and seatbelt use, seat position, and the direction and severity of any impact, and uses all that information to determine the appropriate level of airbag deployment in any incident. Additionally, Jaguar's Protec front head restraint system can minimise whiplash in the event of a rear impact.

Equipment

The new XK range introduces five new alloy wheel designs, some of them replacing earlier designs, some completely new additional choices. Together, they bring the total number of alloy wheel options on the new XK range to seven.

The standard wheel specification is dependent on market and model, but for most markets begins with Jaguar's 18-inch seven-spoke Venus design on XK models. The new 19-inch 10-'V'-spoke Caravela wheel is now standard on XK Portfolio and optional on XK.

Again, depending on market, the all-new 19-inch 10-fan-spoke Artura design is available in painted or chromed finishes and in conventional or run-flat types, and these Artura wheels are offered as options on XK, XK Portfolio and (in run-flat form) also on XKR. Another all-new wheel, the 19-inch ten-spoke Tamana design, becomes standard equipment on Jaguar XKR for most markets other than the UK (which specifies 20-inch wheels), and is unique to this model.

A new 19-inch mini-spare is introduced as standard equipment for the Jaguar XKR, while the weight and space-saving Instant Mobility System still takes the place of a spare wheel on other models in European markets and where 18-inch wheels are fitted as standard.

Distinctive 20-inch wheels continue as a very sporty option across the new XK range - emphasising the cars' sporting dynamics and assertive, muscular looks. The new designs include two 20-inch wheels: the twin-five-spoke Kalimnos will be standard on the XKR in the UK market, and optional for all XK models in other markets. The twin-seven-spoke R Performance Nevis design is a unique option for the Jaguar XKR, and another addition to the wheel range.

With the recent addition of new options Claret, Spectrum Blue, and Kyanite Blue, the stunning exterior colour range for the new XK, XK Portfolio and XKR is extended to 15; two of which - Salsa and Kyanite Blue - are reserved exclusively for Jaguar XKR.

In true, contemporary Jaguar fashion, a great deal of relevant and intuitive technology is controlled by the clear and elegant seven-inch Touch-screen in the centre console - which is standard on all models. The Touch-screen provides access and control for the Climate Control and Audio systems, for the Satellite Navigation System, for Bluetooth mobile connectivity, and for Jaguar's Portable Audio Interface - which are all standard equipment. The satellite navigation system offers DVD mapping, postcode entry, and a traffic message channel. The Portable Audio Interface offers iPod connectivity, and the connection of other storage devices through a USB port, to the in-car sound system, with full Touch-screen control.

The audio system options for the new XK range include single-slot or multi-disc CD changers and either Jaguar Premium Sound or the ultimate, a high-end Bowers & Wilkins system. The Bowers & Wilkins option is a 525-watt system with Dolby® ProLogic®II Surround Sound, three-channel stereo with unique amplifier, Kevlar mid-range speakers with high output and low distortion, and specially designed aluminium tweeters.

Depending on market, a number of Digital Radio options are available: HD radio is available for North American market cars, SDARS satellite radio for North America and Canada, and Digital Audio Broadcasting (DAB) is offered in selected European markets.

2009 Italdesign Giugiaro Quaranta Concept

The "Quaranta" project is a concept car designed to celebrate Italdesign Giugiaro's forty years of business in styling and technological research at the service of the automotive sector.

The Italdesign Giugiaro Quaranta, world-premiered at the 2008 Geneva International Motor Show, is a synthesis of Italdesign Giugiaro's unmatched experience of automotive design: from city cars to super sports-cars, from MPVs to medium-engined saloons up to and including luxury flagships and environment-friendly SUV, not to mention light/heavy duty commercial vehicles, in complete cooperation with leading manufacturers all over the world.

The Italdesign Giugiaro Quaranta is an "extreme" product, an environment-friendly, 4WD super sports-car which incorporates a series of innovative aspects: its styling, but also its drive technology, which combines a hybrid engine with solar energy, and its internal layout which, despite its mid-mounted rear engine, can accommodate three adults and a child, also providing a generous luggage compartment.

The idea which inspired the Italdesign Giugiaro Quaranta project is that of the first single-volume concept car with central engine and drive. The original reference is to the 1968 Bizzarrini Manta which, at that time, represented a major breakthrough in styling, now adapted to state-of-the-art technology and enriched with Italdesign Giugiaro's forty years experience of research.

The style of the future

Despite its flat, highly compact shape, the Italdesign Giugiaro Quaranta features a single-volume shape characterized by a continuous body line stretching from its clipped nose to the tail that exploits the almost horizontal rake of the windscreen.

Access to the cabin is "step-in" via an upper door incorporating the side ones. At the touch of an electric on/off button, the door opens upward in a downwind direction, regulated by proximity sensors. The door is hinged to the hood pillar and is aligned with a second upper rear door, for access to the engine compartment and boot.

The roof houses the array of solar panels, necessary to power the electric battery, in the space between the two doors. Along with the other solar panels positioned on the front end, these create a central opaque strip, a distinctive signature of the model, thanks to the interplay of light with the bright paint of the bodywork. The solar panels can generate a power of up to 250 W, sufficient for the functioning of the cockpit conditioning system and for recharging the electric battery.

The styling of the Italdesign Giugiaro Quaranta prototype is further enhanced by the attention dedicated to surface aerodynamics, designed to ensure maximum possible efficiency and penetration, also by using sharp edges on the rear.

This can also be noted in the front end of the vehicle where the radiator grille has been eliminated and replaced by two side air inlets, positioned above the lighting clusters, which perform the delicate function of front stabilizers. The rear of the vehicle has also been conceived to improve overall aerodynamic performance: an attentively-molded spoiler, with a perfectly square-edged cut and a very technical design, has the scope of supporting the lower wing, modeled according to latest generation F1 styling, that makes up for the absence of the traditional upper stabilizer.

Styling research aimed at top aerodynamic performance is also reflected on the sides, characterized by extremely generous glazing stretching from the front fender to the tail and in which the air vents are housed, located after the doors but also along the sill, in which the water cooling ducts are inserted. The most innovative feature of the side profile is certainly the contour line, between the door-windows and the sill, which is "negative" in the shoulder section, a particular, absolutely innovative feature for super sports-cars.

Interiors: technology for safety and comfort

Inside, the most striking innovation can be found in the multi-control steering wheel which reflects an idea already incorporated in the 1980 Medusa, a prototype developed by Italdesign and on display at its stand in Geneva: all vehicle driving and control functions are concentrated on the spokes, where the stalks have been eliminated and replaced with keys. This guarantees easier control by the driver, in a central position which can be obtained due to the absence of the gearbox-transmission block tunnel. This is possible thanks to the electric four-wheel drive system which eliminates any obstacles on the floor pan, making it completely flat. The generously-scaled central space of the cockpit can accommodate two adults and a child, behind the driver. The dashboard has been conceived with a sporting, modern look, with clean-cut details matching the style of the exterior, and equipped with a vast array of instruments. These are organized on two levels: the screens of the side and rear TV cameras are positioned on the upper level, with particular attention to the left-hand view mirror, useful when overtaking; the lower level is dedicated to the management of the vehicle. The drive-panel also includes a visor for Xray sensors for night driving. The dark-colored leather and alcantara upholstery reflects the most refined Italian taste.

The lighting clusters are extremely modern: the low-beam lights are based on led technology, while the full-beam are of the Bi-xenon type. The direction indicators, the tail and rear stop lights are of the full led type, inserted in a single box but differentiated according to color, assembled and adapted by hand at Italdesign Giugiaro.

Last but not least, the Italdesign Giugiaro Quaranta features 9 ½ by 20" alloy wheels, without hub caps for improved styling and aerodynamics, and four Vredestein tires as standard, which differ only in shoulder height: 275/35/R20 front and 275/40/R20 rear. The dimensions are certainly tight for a super sports-car but suitable for a 4WD car.

Mold-breaking mechanicals

The structure of the prototype is made up of the carbon monocoque frame onto which aluminum and special steel parts are assembled, while the windscreen and roof are made of stratified glass with UVA filter.

The Italdesign Giugiaro Quaranta is fit with electronic four-wheel drive, divided in a small electric motor on the fore-carriage and the thermal engine/electric engine system located in a central rear position. This particular structure, which has seen Toyota's involvement in the electronic control management, has made it possible to develop the vehicle on a 2620-mm wheelbase, ideal for a midengined car.

The batteries which assist the electric motors are located between the engine compartment and the cockpit and are powered directly by the solar panels. The Italdesign Giugiaro Quaranta features a double fuel-tank, integrated in the supporting frame, with a total capacity of 60 liters, giving a mileage of up to 1000 km.

Dynamic asset is variable in two ride height positions: sporting and raised. Maximum ground clearance is 230 mm, an absolute record which means that the super sports-car can take any type of terrain in its stride.

The main technical aspect that distinguishes the mechanical design of the Quaranta is the weight balance and in particular the "weight centering": all the mechanical weight of the vehicle is contained between the two axles, including the mufflers which are positioned in front of the rear wheels. Only the radiator and a large overhanging luggage compartment, able to accommodate two golfbags, remain outside.

The front suspensions also represent a breakthrough: designed according to F1 cars, they are equipped with a central mono-shock echoing an idea already presented by Italdesign - Giugiaro on the 2004 Toyota Volta and on the 1997 Alfa Romeo Scighera. The linkage mechanism of the levers guarantees exceptional stability in any type of situation, simulating a "multilink" mechanism. The links have been designed and engineered entirely by ITALDESIGN GIUGUIARO: the "ovalized" down tubes are made of special steel and the uprights of Ergal.

The entire Quaranta project is an idea of Italdesign Giugiaro, constructed in accordance with the classical formula of the package of services furnished to automotive manufacturers.

Quaranta confirms the classic Italdesign - Giugiaro versatile service formula for car manufacturers. The competence and capability of designing a new car model considering style development, frame development, safety and ergonomics analyses and mechanics development, starting only from a given functioning engine.

The chassis, bodywork and layout of the Italdesign Giugiaro Quaranta prototype have been designed by the Engineering Division of Italdesign Giugiaro, while the mechanicals and electronics have been developed in cooperation with Toyota. The vehicle was entirely built at the Moncalieri facilities.

2008 Infiniti G37 Coupe

The all-new 2008 Infiniti G37 Coupe, which made its world debut at the 2007 New York International Auto Show, combines the exhilarating performance, stunning styling and modern, sporty interior of the original Infiniti G Coupe and accelerates each to new levels. Among the key enhancements to the new second-generation G Coupe are a larger, more powerful 3.7-litre V6 engine, available advanced 4-Wheel Active Steer system, a dramatic new exterior design and a refined interior with intuitive, integrated technology. The Infiniti G37 Coupe joins the recently introduced, all-new 2007 Infiniti G35 Sedan in Infiniti showrooms nationwide in August.

"The new G35 Sedan, which has been named to both Car and Driver's '10 Best Cars' and Automobile magazine's 'All-Stars' list, has set the stage for the introduction of the new Infiniti G37 Coupe," said Mark Igo, vice president and general manager, Infiniti Division. "The new Coupe builds on the styling, performance and interior enhancements of the G Sedan, adding the dynamic style, sporty atmosphere and expressive driving character expected of a class-leading luxury sport coupe. The line starts here."

Exhilarating Performance From a New Engine Design

Leading the enhancements to the 2008 Infiniti G37 Coupe is the first-ever application of the new 3.7-litre V6 engine with VVEL (for Variable Valve Event and Lift).

Estimated at 330 horsepower and 270 lb-ft of torque, the new "VQ37VHR" contains approximately 35 percent new and unique parts from the new VQ35HR engine introduced in the 2007 G35 Sedan just last year. Both the Coupe's VQ37VHR and the Sedan's VQ35HR engines are based on the award-winning VQ engine series, named one of the "Ten Best Engines" by Ward's Auto World magazine for 13 consecutive years.

Along with utilising a larger displacement than the previous 3.5-litre powerplant, the Infiniti G37 Coupe's new VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response. The VVEL system is also expected to improve emissions and fuel efficiency. The VVEL intake camshafts, featuring continuously variable lift control teamed with the Continuously Variable Valve Timing Control System (CVTCS), allow for a 7,500 rpm redline.

The engine also features increased cylinder block height (from the previous 3.5-litre design), ladder frame construction for greater rigidity, large crank journal and pin diameters, asymmetric piston skirts, twin knock sensors, an electronically controlled "drive-by-wire" throttle system, molybdenum coated lightweight pistons, Iridium spark plugs and a symmetric twin air intake system.

A new, specially tuned dual exhaust system has been designed with equal length exhaust manifolds and low muffler exhaust backpressure to help improve engine breathing. Both intake and exhaust enhance driving pleasure with their authentic performance notes.

Rated at an estimated 330 horsepower, the new engine is not only considerably more powerful than the previous generation G Coupe (rated at 275 hp with 5AT, 293 hp with 6MT), but is expected to offer increased fuel mileage and reduced emissions levels. Overall vehicle fuel economy improvements are estimated to be nearly one mpg better than the G35 Sedan and nearly two mpg better than the previous generation Infiniti G35 Coupe (actual EPA mileage estimates and emission information to be announced at a later date).

"The new 3.7-litre V6 is a true powerhouse - becoming more enjoyable as you drive it," said Igo. "And, this powerplant also features Infiniti's trademark "Swell" acceleration - introduced on the new G Sedan last year - with special tuning that builds horsepower almost continually to the redline like a building wave."

The Infiniti G37 Coupe engine is backed by a choice of an upgraded electronically controlled 5-speed automatic transmission with manual mode, downshift rev matching, DS mode and ASC (Adaptive Shift Control) that allows for quicker shifts in sporty driving situations and available genuine magnesium paddle shifters; or a newly revised, lightweight 6-speed manual transmission.

Performance Platform and Suspension

Developed at test circuits throughout Europe - including the famed Nürburgring - the Infiniti G37 Coupe was conceived as a performance thoroughbred. Handling and ride performance increases come from the Infiniti G37 Coupe's enhanced FM (Front Mid-ship) platform, which has been stiffened 36% from the previous generation, is lower in overall height and has a wider front and rear track width.

The Infiniti G37 Coupe's 4-wheel independent suspension design features lightweight aluminium components and large front and rear stabiliser bars, increased spring rates and optimised suspension damping.

The front suspension is a double-wishbone design, with a single pivot lower wishbone and a long upper link. The multi-link rear suspension separates the shock absorbers and springs, locating the shock absorber inline with the wheel centre. These designs help minimise alignment changes and reduce suspension friction for nimble handling and smooth riding characteristics.

Steering is provided by a twin-orifice vehicle-speed-sensing design, which provides optimum steering effort at both high and low vehicle speeds. Standard on all Infiniti G37 Coupes is Vehicle Dynamic Control (VDC), which assists in enhancing vehicle stability under a variety of driving conditions.

Also available on the new Infiniti G37 Coupe is Infiniti's exclusive 4-Wheel Active Steer system (4WAS), with unique chassis configuration that features automatically variable front steering ratios and rear suspension geometry that adjusts to steering input and vehicle speed via motor-driven controls. The system's electronic control unit calculates the desired vehicle dynamics from a series of sensors, including vehicle speed and steering angle, and separately directs both the front and rear actuators to change steering gear ratios and rear geometry by moving both the front steering gear and rear suspension lower links - thus providing sports car-like agility and secure stability.

Braking performance is provided by standard 4-wheel vented discs with 4-channel, 4-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). The standard Infiniti G37 Coupe adopts the "sport" braking system of the recently introduced G35 Sedan. The Infiniti G37 Coupe Journey with Sport Package and Infiniti G37 Coupe Sport 6MT are further enhanced with aluminium four-piston callipers (front)/two-piston callipers (rear) embossed with Infiniti lettering and large ventilated rotors - 14.0-inch front and 13.8-inch rear.

Also available on Infiniti G37 Coupe is Infiniti's Intelligent Cruise Control (ICC) with Preview Braking, which provides a precise following distance from the vehicle ahead. It also identifies sudden braking situations with laser sensors to determine distance and relative speed of the vehicle ahead in the same lane and "pre-pressurises" the Brake Assist system before the driver steps on the brake pedal.

A new 18-inch wheel and tyre package is standard on Infiniti G37 Coupe, featuring a "split 5-spoke" 18x8-inch aluminium-alloy wheel design with P225/50VR18 all-season tyres. A new 10-spoke 19-inch wheel and tyre package, with lightweight cast aluminium wheels and high performance tyres, is also available. A Tyre Pressure Monitor System (TPMS) is standard on all 2008 Infiniti G37 Coupes.

To enhance the already high level of dynamic performance, the Infiniti G37 Coupe 6MT and Infiniti G37 Coupe Journey with Sport Package come standard with unique sport suspension, a Viscous Limited Slip Differential (VLSD) and a new wheel and tyre package with 19x8.5-inch front wheels with 225/45WR19 front tyres and 19x9-inch rear wheels with 245/40WR19 rear tyres.

Seductive Styling

The Infiniti G37 Coupe's advanced performance systems are wrapped in an all-new seductive skin, giving the vehicle a kinetic feeling with emotional surface expression, sweeping character lines and tight panel gap lines.

"Compared with its predecessor, the Infiniti G37 Coupe is longer, lower and wider - indicative of the power and technology of the vehicle," said Igo.

Exterior highlights include flowing front fender curves, a wave-style hood, expressive front fascia with Infiniti's signature double-arch grille and L-shaped High-Intensity Discharge (HID) bi-xenon headlights with integrated fog lamps. As with the new G35 Sedan, Infiniti developed a specialised production process for headlight installation to impart tight build tolerances and an exacting fit of the complex front fascia. The aluminium hood is secured by dual latches located at the two front corners to ensure an excellent fit.

The strong side character line and side sills integrate with the large wheel wells and the 18- or 19-inch performance-oriented wheel and tyre packages to transmit an added sense of power and vibrancy.

The rear of the G Coupe features broad rear fenders, flowing into the large LED taillights - an Infiniti trademark, refined rear bumper, integrated RearView Monitor camera (when equipped), rear underbody air diffusers and large dual exhaust outlets with chrome finishers.

An available rear spoiler gives the Infiniti G37 Coupe zero rear lift, matching the standard zero-lift front aerodynamics.

The Infiniti G37 Coupe Sport 6MT models and Infiniti G37 Journey with Sport Package add an enhanced performance look, with a unique front fascia, special side sills and standard 19-inch aluminium-alloy wheels with high performance tyres.

Eight exterior colours, including two all-new colours, are offered.

Sophisticated, Luxurious Interior

The 2008 Infiniti G37 Coupe interior design features sophisticated craftsmanship, with a cockpit-oriented front driver and passenger area, Infiniti signature "double wave" instrument panel design featuring the Infiniti-signature analogue clock and dramatic, full-length centre console with a leather and aluminium-clad shifter. Special aluminium-alloy interior trim, inspired by elegant, handmade Japanese Washi paper, is located across the instrument panel, on the centre console and on the door panels. Genuine African Rosewood trim is also available.

The instrument panel features Infiniti electroluminescent instrumentation with white-and-violet illumination and integrated multi-function information drive computer (average fuel consumption, real-time fuel economy, average speed, elapsed time, running distance, distance to empty, outside air temperature, warning displays, odometer and automatic transmission shift indicator) display.

Drivers grip a double hand-stitched leather-covered steering wheel, designed for maximum comfort and usability with wheel-mounted audio and cruise controls. Available genuine magnesium paddle shifters for the 5-speed automatic transmission fall readily to hand and add control (Infiniti G37 Coupe Journey with Sport Package only).

The 8-way power driver and 4-way front passenger seats (8-way on Infiniti G37 Coupe Journey, G37 Coupe Journey with Sport Package and Infiniti G37 Coupe Sport 6MT model) are appointed with Infiniti's exclusive premium leather and feature 2-way adjustable head restraints and a unique rear-seat access system, whereby the front seats will move forward automatically at the touch of a button to allow passengers into the rear seat.

The Infiniti G37 Coupe Journey with Sport Package and Infiniti G37 Coupe Sport 6MT add special 14-way sport-styled seats with thigh extensions and power adjustable torso and thigh bolsters for the driver, unique steering wheel stitching and high-grip aluminium pedals.

Technological and convenience features abound in the new Infiniti G37 Coupe. Standard is the Infiniti Intelligent Key with push button ignition, Remote Keyless Entry system, a tilt/telescoping steering column with increased travel, illuminated glove compartment and automatic temperature control.

Also standard is a 6-speaker AM/FM/CD audio system with mp3 playback capability, Radio Data System (RDS) and centre console-mounted auxiliary input, as well as a 7-inch colour display.

Available is an 11-speaker Infiniti "Studio on Wheels"™ by Bose®, combining a 3-way front door speaker array using 10-inch woofers with an audiophile-quality head unit incorporating double oversampling 24-bit 96KHz Burr Brown® Digital Analogue Converters (DAC).

Safety Performance and Technology

Available on the new Infiniti G37 Coupe is an Adaptive Front lighting System (AFS), which automatically controls the headlight lighting pattern according to steering angle and vehicle speed to help provide better visibility at night.

Standard on all Infiniti G37 Coupes is an Advanced Air Bag System (AABS) with dual-stage supplemental air bags with seat belt sensors and occupant classification sensor, front-seat side-impact supplemental air bags and roof-mounted side-impact curtain air bags for front- and rear-seat occupant head protection.

Also standard are 3-point ALR/ELR seat belts (driver's side ELR only) and front seat belts with pretensioners and load limiters and adjustable upper anchors, driver and front-passenger knee bolsters, front seat Active Head Restraints and the LATCH (Lower Anchors and Tethers for CHildren) system. Available as part of the Technology Package are brake-operated pre-crash seat belts with motion sensor on the brake pedal.

The Infiniti G37 Coupe features Zone Body Construction with front and rear crushable zones to help disperse crash energy around the passenger compartment. For occupant safety, the engine is designed to move under the occupant compartment in a high-speed frontal collision, while a breakaway construction of the propeller shaft (connected with the engine-drop function) and the double-wall construction of the bulkhead helps to minimise cabin deformation, especially in the lower leg area. In addition, the brake pedal is designed to collapse to help reduce lower leg injuries in a severe crash.

Three Well-Equipped Models

The 2008 Infiniti G37 Coupe is available in three models: G37 Coupe, G37 Coupe Journey and G37 Coupe Sport 6MT. In addition to the long list of standard features on all three models, several options and packages are available.

These include the Premium Package, with a power sliding glass moonroof, 11-speaker Infiniti "Studio on Wheels"™ by Bose® audio system with iPod connection, memory system (driver's seat, steering wheel and outside mirrors) with synchronisation, power tilt and telescoping steering wheel, anti-glare rearview mirror with compass and HomeLink© Universal Transceiver, Bluetooth® hands-free phone system, and heated front seats and door mirrors.

2009 Infiniti FX50

In keeping with Infiniti's well defined product strategy, the new FX is inviting in every dimension, from the nimble feel of its quick and controlled response to driver input, to the ride comfort provided by its Dual Flow Pass shock absorbers and quick response to body motion inputs, to the unique "Infiniti feel" under acceleration and braking.

Infiniti's designers and engineers' overall goal in the development of the second-generation FX crossover was to enhance its "sports car ability" while adding refinement - without compromising either side of the equation. The new FX's creators also wanted to give the vehicle a more "human" feel, despite its mechanical strengths, by integrating the latest technology with owners' lifestyles.

The new Infiniti FX50 is designed to be highly adaptive to both the driver and driving conditions, utilizing a long list of Infiniti technologies and systems, including Variable Valve Event & Lift (V-VEL) engine technology, Adaptive Shift Control, Suspension with active Continuous Damping Control (CDC), Rear Active Steering, Around View Monitor, Intelligent Cruise Control (Full Speed Range) and Intelligent Brake Assist (IBA).

2009 INFINITI FX EXTERIOR

The new Infiniti FX continues with the breathtaking exterior styling and "sports car proportions" that helped the original stand out from all other performance luxury crossovers on the market. The FX blends the substantial lower body of an SUV with the long hood, stretched wheelbase, short front and rear overhangs, low overall height and elegant upper body more commonly found on sports cars - conveying its strong performance personality and breakthrough design architecture at a single glance.

For the new FX generation, distinctive side air vents have been added behind the front wheels. Also, the front wheels have been moved 35 millimeters forward (from the previous generation FX) and the front track has been widened by 50 millimeters - providing an even more pronounced performance stance.

The FX's design starts with a new front end appearance, led by a lustrous Infiniti signature double-arch front grille, standard fog lamps and Bi-Xenon headlights. The Infiniti FX50 also includes an automatic-on feature that switches on the headlights automatically on at dusk and a standard Adaptive Front lighting System (AFS). This system automatically controls the lighting pattern and directional aim, based on steering wheel angle and vehicle speed (the headlights can swivel headlights up to 17 degrees).

The FX's new flat blade windshield wipers and wiper arm design optimize aerodynamic performance - helping improve wiping performance at high speeds and reducing wind noise at high speed. A new rain-sensing feature automatically tunes the wiper pace and speed according to the frequency of the precipitation (as detected by sensors).

The new side air vents are also functional, allowing air to flow from inside the engine compartment to outside the vehicle, reducing high under-hood air pressure. The side vents reduce front end lift by five percent for improved high speed stability.

The Infiniti FX's aggressive silhouette is highlighted by a strong front-to-rear shoulder line, "taut canopy" greenhouse with chromed window frames, rearward-sloping roofline, integrated rear spoiler and polished roof rails. In the rear, the FX's simple, bold appearance features LED taillights that extend beyond the body to help create aerodynamic down force and large dual exhaust outlets with chrome finishers.

The FX's coefficient of drag has been improved to 0.35 from 0.37, with the engineers finessing even the smallest details to help manage airflow, including the front bumper sides, rear spoiler angle and taillight shape.

Under the FX's polished, assertive styling is an equally advanced body structure. FX utilizes the rigid FM (Front Midship) platform architecture used on the Infiniti G 37, G37 Coupe. The FM platform offers sports car-like front-to-rear weight balance - 54/46 - for exceptional handling.

Additional development was undertaken to reduce weight and enhance body strength. For example, the FX's aluminum front and rear door panels, which have the same strength and stiffness of conventional steel doors, are 20 kilograms lighter (total for all four doors), allowing the FX to maintain a power-to-weight ratio that is among the best in class. The FX weights 90 kilograms less in body structure weight alone. The new FX's body is also 1.6 times more resistant to twisting and 3.4 times more resistant to bending than the previous generation FX design.

The new FX utilizes Infiniti's advanced "Scratch Shield" paint, a special "self-healing" clearcoat paint designed to maintain its gloss-level over time. The paint "repairs" fine scratches, such as fingernail scratches under door handles, restoring the FX's surface close to its original state. The Infiniti FX50 is offered in seven exterior colors.

2009 INFINITI FX INTERIOR

The Infiniti FX's sporty interior is designed to combine a driver-oriented cockpit/command center with a warm, modern, comfortable passenger environment - all wrapped in rich, natural materials. The high-tech interior design includes an Infiniti signature "double-wave" instrument panel and white-and-violet electroluminescent gauges.

The Infiniti FX50 comes with a new front sport seat design with an adjustable air-type side support system for added lateral support during "sporty" driving sessions. The driver's seat features 10-way power-adjustability with lumbar support and a 2-position Driver's Seat Memory system, while the passenger's seat is an 8-way power-adjustable design. Covered in a special quilted leather sew pattern, the front sport seats include adjustable thigh extensions, which add an extra level of comfort for drivers and passengers with long legs or for long distance travel. Whereas the front seats include an enhanced climate controlled system with heating and cooling functions for maximum comfort.

Standard on the Infiniti FX50 is a new Automatic Driving Position System, which moves the seat, steering wheel and outside mirrors adaptively into the correct position. This system allows the driver to change the seat position while driving and keep the same viewpoint and relationship between the steering column and driver's shoulder position.

The FX interior offers white-and-violet "Fine Vision" electroluminescent gauges with "gear-like" rings on the instrument cluster meters, standard 8.0-inch multi-information display monitor and signature Infiniti analog clock. The center console/shifter area is available in a black quartz finisher or special Curly Maple wood trim, inspired by classical violins, giving a sense of warmth throughout.

The FX interior also offers a leather-wrapped steering wheel and shift knob, along with front door pockets, front seatback pockets, dual front and rear cup holders, locking glove compartment and four assist grips. Other standard equipment includes four 12-volt power outlets, all power windows with one-touch up/down function and power door locks, cargo area tonneau cover and cargo multi partition net, along with aluminum pedals, power tilt and telescoping steering wheel, Infiniti Intelligent Key with push button start and a special 12-point "welcome lighting" system.

The thoughtful design behind the interior of the Infiniti FX extends to the available custom-engineered Bose sound system. The acoustic effect of nearly every interior detail was analyzed. Then, the 11-speaker system was customized for the unique acoustic environment inside the FX. As a result, each listener can enjoy music that approaches the power and emotion of a concert hall performance."

Occupant comfort takes many forms in the new Infiniti FX50, including the air that driver and passengers breathe. A standard filter, using fiber impregnated with natural grape seed polyphenol, has the ability to neutralize allergens that conventional filters cannot remove due to their incredibly small size (0.3 to 0.5 microns).

The Infiniti FX50's advanced Infiniti Navigation System features a 7-language media display and coverage of more than 30 European countries, along with an advanced RDS-TMC system with real-time traffic information system. A Voice Recognition system comes with the navigation system and includes voice activation for common climate control, navigation, audio system and phone functions.

The 2009 Infiniti FX is offered in three interior color schemes.

INFINITI FX50 DRIVETRAIN

The Infiniti FX50 features a new powerplant, which makes it debut on this model - an advanced 5.0-liter V8 that is mounted low in the chassis to help lower the Infiniti FX50's center of gravity. The engine design includes twin symmetrical air intakes, microfinished crankshaft, lightweight pistons, super-silent cam drive chains and an electrically driven cooling fan to help optimize performance.

The goals for the development of the Infiniti FX50's all-new VK50VE V8 started with outstanding power output - 390 horsepower (287kw) and 500 Nm of torque - a high rev limit, a powerful engine sound from a specially tuned exhaust and improved fuel economy versus the previous generation FX45. Even small details were evaluated in designing the new engine, including control of oil mist density in crankcase for reduced friction

One of the keys to the new V8's impressive performance is the adoption of Infiniti's patented Variable Valve Event & Lift (VVEL) valve control technology, which was first introduced on the Infiniti G37 Coupe. The VVEL system continuously adjusts valve event and lift amounts, enabling higher fuel efficiency with higher torque and improved emissions over conventional variable valve designs. The VVEL intake camshafts, which feature continuously variable lift control teamed with a Continuously Variable Valve Timing Control system (CVTC), allow for a 6,900 rpm redline and a high compression ratio of 10.9:1.

The Infiniti FX50 is comes standard with a new seven-speed automatic gear box with Adaptive Shift Control (ASC) allowing a downshift blip control. FX50's standard magnesium paddle shifters enable drivers to shift the transmission without releasing their hands from the steering wheel, helping maintain stability for the driver when accelerating or decelerating on winding roads.

Infiniti's advanced ESP system with Traction Control System (TCS) is standard on all FX models. ESP adjusts brake pressure and engine torque automatically in understeer, oversteer or slippery road surface situations, helping the driver keep the intended path. A cancel switch allows the driver to switch off the ESP system when desired.

The Infiniti FX50 is equipped with Infiniti's intelligent four-wheel drive system called ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split), which uses an advanced torque split control strategy that automatically transfers optimum torque to the wheels according to road and driving conditions. The system provides outstanding handling due to optimum torque distribution from front to rear (50:50 up to 0:100). ATTESA E-TS also provides high starting traction performance and smooth, stable acceleration, especially in snow-covered or off-road situations with a 50:50 torque split at standing start.

When the Infiniti FX50 accelerates from a standing stop, the ATTESA E-TS system provides power to all four wheels. Once up to speed, if the system's sensors detect that all-wheel drive is not needed, up to 100 percent of the power is sent to the rear wheels. This rear-bias offers better handling balance and improved fuel efficiency. The system can then divert power forward at any time as traction/road conditions dictate, helping ensure that power always goes where grip is the greatest.

The Infiniti FX50's dynamic handling is a result of its suspension using light weight and aluminium components in the front and rear to reduce unsprung weight (weight not supported by the springs), helping to improve both ride and handling.

The new double-wishbone front suspension design, similar to that utilized on the Infiniti G37 and G37 Coupé, replaces the previous generation FX's front strut-type suspension. The suspension's upper and lower A-arms help provide superior control of a wheel's motion, especially when the suspension compresses and extends, providing more travel than the previous strut design. The net result is a better ride and improved handling.

The Infiniti FX50's rear suspension utilizes the multi-link design from the previous generation, refined to weigh less and provide more wheel travel - again for improved ride and handling. A lightweight, high-strength steel rear subframe is utilized to isolate the FX's body and its passengers from road noise and vibrations. Its compact design benefits to room in the rear passenger and cargo area. Large diameter stabilizer bars are utilized front and rear.

The suspension system also incorporates special "dual flow pass" shock absorber technology with rebound springs for responsive yet comfortable ride and firm, tight handling.

The new Infiniti FX50 includes standard active Continuous Damping Control (CDC) system with special electronically controlled shock absorbers. Unlike conventional fixed damping force shock absorbers, the suspension with active Continuous Damping Control (CDC) takes the input from a variety of sensors and continuously alters the damping of the shocks to provide optimal ride and handling. The system features a driver-selectable switch with two settings, "Auto" and "Sport," allowing the driver to control the shock valving levels.

The Infiniti FX50's standard Rear Active Steer system is the first of its kind available in an SUV. Unlike passive rear steering systems, this design features precise, electronic motor-driven control to turn the rear wheels up to one degree, helping generate a nimble steering response at low speeds and enhance stability at high speeds. Rear Active Steer moves the Infiniti FX50's rear wheels in accordance with the front-wheel steering angle and vehicle speed, rather than passively following the front wheels. The result is a vehicle that is able to change direction with improved quickness, precision and stability.

The new FX maintains its small turning radius (5.6m) despite its larger wheel and tire package. Its engineers focused on improving steering feedback from the advanced speed-sensitive rack-and-pinion power steering system and reduced "play" in the steering mechanism for more direct vehicle response to steering input.

Secure braking performance is provided by the Infiniti FX50's 4-wheel ventilated disc brakes with Brake Assist (BA) and Electronic Brake force Distribution (EBD). The Infiniti FX50 system features 4-piston front/2-piston rear calipers, similar to those utilized on the new Infiniti G37 Coupé, and large brake rotors (355x22 mm front/350x20 mm rear). Braking system dimensions and high thermal capacity have been tailored specifically to European driving needs, providing a secure and stable feeling at very high speeds and high deceleration rates.

The Infiniti FX50 features metallic-finish six-spoke cast-alloy 9.5Jx21-inch wheels made by Enkei. These wheels are created using a special type of ultra-lightweight casting and are as light as a competitor's 18-inch wheels. They are mounted with 265/45R21 performance tires.

INFINITI FX50 TECHNOLOGY AND SAFETY SYSTEMS

The new Infiniti FX50 offers a wide range of advanced available technology and safety systems, helping reinforce the strong sense of communication between the Infiniti FX50 and its driver - as well as providing a secure and inviting feel.

The Infiniti FX50 comes standard with the unique Infiniti Around View Monitor utilizes four small superwide-angle cameras - mounted on the front, side and rear of the Infiniti FX50 - to project an all-around view of potential objects on every side of the vehicle, helping reduce blind spots when parking. The system uses advanced image processing to provide a unique "Birds-Eye View" of the vehicle, making it easy for the driver to position the Infiniti FX50 for parallel parking by simultaneously confirming the exact placement of the front and rear of the vehicle. The system includes front and rear sonar sensors for camera assistance, also displayed in an easily understandable fashion on the display.

The Infiniti FX50's standard Intelligent Cruise Control (Full Speed range) system combines the brakes, throttle and laser rangefinder with the cruise control system to automatically maintain a set distance between the Infiniti FX50 and a vehicle in front of it. FX50's Intelligent Cruise Control operates in "Full Speed Range" (from 0km/h) hence reducing the driver's workload in congested traffic as well as smooth long distance travel. The Intelligent Cruise Control assists the driver with acceleration and deceleration actions and stops the Infiniti FX50 if traffic requires.

Standard on the Infiniti FX50's, Intelligent Brake Assist (IBA) system uses the laser rangefinder from the Intelligent Cruise Control's (ICC) system and analyzes closing speeds to a vehicle ahead to help prevent or reduce damage caused by a rear-end collision. If a forward collision is imminent with the vehicle in front of the Infiniti FX50 and the driver must take immediate avoidance action, the system sounds a warning to prompt driver action. When a rear-end collision cannot be avoided by the driver's action, the system activates the brakes to decelerate the vehicle, thereby helping to reduce damage resulting from the collision. IBA can apply up to 0.5g braking force (1.0g is considered close to the maximum possible braking force).

The FX's enhanced FM platform Zone Body Construction is designed to help protect occupants in a collision by helping to absorb crash energy through use of front and rear crushable zones. In a high-speed frontal collision, for example, the crushable zone crumples while the engine is designed to move under the occupant compartment. This has the effect of expanding the crushable zone, thereby helping to reduce deceleration g-force and simultaneously helping minimize cabin deformation, especially in the lower leg area. In offset impacts, the body construction helps decrease the amount of cabin deformation. Special high-resistance steel is used for light weight and improved strength.

As with all Infiniti vehicles, significant time was spent to ensure excellent passenger safety. The first-generation FX received 5 Stars for all measures in the U.S. National Highway Traffic Safety Administration (NHTSA) New Car Assessment Program (NCAP) testing, and the new second-generation FX is expected to offer similar or better occupant protection.

Other standard safety features found on the Infiniti FX50 include a seat belt reminder system; airbags for driver and front passenger with front hip-thorax side airbags and front-to-rear curtain airbag for rear passengers. Also standard are 3-point front seat belts with pretensioners and load limiters, front seat Active Head Restraints.

The Infiniti FX50 also features a breakaway brake pedal and double-wall bulkhead construction to help reduce lower leg injuries and a breakaway construction of the propeller shaft (connected with the engine-drop function).

The Infiniti FX50's standard Tire Pressure Monitoring System (TPMS) uses pressure sensors with transmitters mounted inside each wheel, which transmit data by radio wave to a control module, sending tire pressure information to a center display indicator on the Infiniti FX50's information panel. A warning lamp and display indicates when a low tire pressure condition (less than 75 percent of normal pressure) is detected.
