Latest Car Extreme

The Jaguar XKR Special Edition combines a number of new features and option packs that are introduced to the XK range at 2011 Model Year. Jaguar customers have the option to personalise their vehicle by building on the existing Jaguar XKR package to deliver a car that offers even greater performance without sacrificing the refinement and luxury for which every Jaguar is renowned.

Introduced in 2009, the Jaguar XKR boasts a state-of-the-art 5.0-litre supercharged AJ-V8 Gen III R engine that delivers 510PS (510bhp SAE), 625Nm of torque and propels the coupe to 60mph in just 4.6 seconds. Now, in Special Edition guise, the Jaguar XKR's top speed climbs significantly from an electronically limited 155mph (250km/h) to 174mph (280km/h) thanks to the addition of the Speed Pack. Allied to that remarkable engine is an advanced six-speed automatic transmission with steering-wheel mounted paddles, lightweight aluminium body structure and a range of computer-controlled systems including Active Differential Control and Adaptive Dynamics that ensure the supercharged car accelerates even faster, handles even more precisely and sets new standards of ride and comfort.

The benefits of the Jaguar XKR's lightweight but stiff and strong advanced all aluminium body are already acknowledged. Not only does this architecture bring dynamic benefits thanks to its torsional rigidity, it also offers excellent safety and crash repair features and provides the ideal base to improve performance across the board - including optimised fuel economy and CO2 emissions. Thanks to the combination of excellent powertrain efficiency and the Jaguar XKR's advanced lightweight body architecture, its fuel economy is comparable to the previous generation of Jaguar XKR - despite the significant increases in power and performance.
The new 2011 Jaguar XKR Special Edition consists of two new styling and performance packs - the Speed and Black Pack. Both are available to Jaguar XKR coupe customers separately and provide new levels of styling and performance for owners looking to further personalise their Jaguar.

The Jaguar XKR Speed Pack
The Jaguar XKR with new optional Speed Pack allows customers to further strengthen their XKR's already impressive breadth of capability, by extending the car's top speed from 155mph (250km/h) to an electronically limited 174mph (280km/h), thanks to a unique engine and transmission recalibration.
Every Jaguar XKR with the Speed Pack will come with body-coloured side sills and rear diffuser, and a chrome finish to the window surrounds, upper and lower mesh grilles, side Power Vents and boot lid finisher. Red brake callipers with a Jaguar 'R' logo sit inside 20-inch Kasuga alloy wheels.

The performance potential of the supercharged AJ-V8 Gen III R engine comes courtesy of its highly advanced design. The all-aluminium four-cam power unit has 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 AJ-V8 engine is built around a stiff, aluminium block with cast-in iron liners and cross-bolted main bearing caps to reduce noise, vibration and harshness. The block is high pressure die-cast, providing a superior finish and greater dimensional accuracy. The engine uses 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.

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 more than 20 percent over its predecessor. It also improves noise quality to the point where the unit is 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. 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.

The charge cooling effects of the direct-injection fuel system have allowed the compression ratio of the supercharged engine to increase from 9.1:1 to 9.5:1, further optimising fuel economy. 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.

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 Jaguar XKR Black Pack
For customers looking to create a real statement with their Jaguar XKR, the new optional Black Pack allows them to own a bold and purposeful Jaguar with undeniable visual impact thanks to menacing gloss black wheels and exterior detailing.

Like the Speed Pack, XKRs fitted with the Black Pack have a paint palette that is restricted to colours that Jaguar's Design team believe to be ideal for creating a coupe with immediate exclusivity. The Black Pack models will be available in Ultimate Black, Polaris White or Salsa Red and boast eye-catching 20-inch gloss black Kalimnos alloy wheels. Further gloss black finishing is applied to the window surrounds, front grilles and side Power Vents. Optional red painted brake callipers contrast strongly with the black alloy wheels, while body coloured front and rear spoilers and boot lid finisher round out the package. Customers also have the option to apply a sweeping 'XKR' side body graphic that runs along the door sills.

Jaguar's Design Director, Ian Callum, says the new Black Pack is a fitting addition to the Jaguar XKR: "While Jaguars are about beauty, they are also about speed and power. With the optional Black Pack you can now add a sense of drama and severity to that performance."

In addition to the Black Pack's exterior changes, the Jaguar Designers' Choice programme has also selected a range of interior trims that support the visual impact of the car. All XKRs with the Black Pack will be trimmed with Charcoal leather hides that can be personalised with a range of colour stitching and grain. Three interior finishes and veneers for the fascia and door trims are also available - Dark Oak, Dark Mesh Aluminium and Piano Black.

Whatever interior trim is selected, the Jaguar XKR's cabin is evidence of contemporary, sporting luxury, exceptional quality of craftsmanship, and Jaguar's renowned attention to detail. The interior is clean, elegant and spacious, and remains entirely in harmony with the sporting character of the revised exterior.

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.
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 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.

The 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.

The 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.
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.

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.

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.

Sleek, sporting and sophisticated, the all-new Jaguar XJ brings a daring new spirit to automotive luxury. It offers a seductive mix of striking design, breathtaking performance and engineering without compromise.

The new Jaguar XJ is the epitome of fluid, contemporary automotive style. The elongated teardrop shape of the side windows establishes the car's silhouette and lies at the heart of its flowing design. And the new Jaguar XJ doesn't just look streamlined: it shares a drag coefficient of 0.29 with the Jaguar XF saloon, making them the most aerodynamic Jaguars ever.

A coupé profile cloaks a cabin that offers comparable levels of space to saloons with a more conventional style. There is generous accommodation for five occupants, while long-wheelbase models provide rear-seat passengers with even greater levels of comfort thanks to an additional 125mm of rear legroom.

The exquisitely designed interior has a strong sporting character throughout. A panoramic glass roof, standard on all models, dramatically enhances the sense of light and space inside the new Jaguar XJ. And in keeping with its status as the ultimate four-door Jaguar, the XJ introduces a new generation of interior technologies, pioneering the use of display and infotainment systems such as the innovative Virtual Instrument dials and optional 1200W Bowers & Wilkins premium surround sound system.

At the heart of the all-new Jaguar XJ's construction is a next-generation application of Jaguar's unique lightweight vehicle architecture. Primarily aluminium, but also using magnesium and composite alloys, this allows Jaguar to produce a significantly lighter and stiffer body - the lightest in its class. The new structure - which retains the same aerospace-based riveting and bonding processes - has been refined using these advanced materials to deliver improved strength, enhanced refinement and superior safety performance.

The new Jaguar XJ offers the choice of four powerful and refined engines, which use the latest powertrain technology to deliver an outstanding combination of performance and class-leading efficiency. The supremely powerful supercharged 510PS 5.0-litre AJ-V8 Gen III will head the line-up, with a 0-60mph time of 4.7 secs (0-100kph in 4.9 secs); 470PS supercharged and 385PS naturally aspirated petrol V8s are also available, dependent on market.

A no-compromise diesel alternative is provided by the formidable 275PS 3.0-litre AJ-V6D Gen III. With twin sequential turbochargers, this is an engine that delivers on every aspect of the Jaguar driving experience, marrying tremendous drive (0-60mph in 6.0 secs, 0-100kph in 6.4 secs) with impressive fuel economy and CO2 emissions (40.1mpg and 184g/km of CO2).

The all-new Jaguar XJ delivers a driving experience that is just as memorable as the car's appearance. Benefitting from technologies pioneered on the exciting new Jaguar XFR and Jaguar XKR models, including continuously variable damping (Adaptive Dynamics), electronically controlled rear differential (Active Differential Control) and a quick ratio power-steering system, the new Jaguar XJ combines responsive, sporting dynamics with the refined, supple ride expected from a luxury Jaguar.

With its unique lightweight aluminium body structure and new, advanced powertrains, the all-new Jaguar XJ already has a head start when it comes to sustainable performance. The aluminium body uses more than 50 percent recycled material, with a plan to increase this to 75 percent. Body panels made from recycled material use only 5 percent of the energy required for new aluminium, equating to a potential saving of three tonnes of CO2 per vehicle.

THE CONCEPT
The all-new Jaguar XJ's distinctive lines mark the next bold evolution of Jaguar's new design language. The striking elongated teardrop shape of the side window graphic establishes the car's streamlined profile, and is balanced by a dramatic lower swage line emanating from the front wheels that reinforces the vehicle's forward stance. The new Jaguar XJ's sleek lines are complemented by a taut waistline, which further accentuates the impression of length and elegance and creates a natural tension as it fades from the front arch into the middle section of the car before reappearing as a strong haunch towards the rear.

Bold, confident face
The face of the XJ is confident, with a wide front track and short overhangs contributing to the finely judged proportions. The nose of the car follows Jaguar's new design language, with a bold and assertive treatment: the powerful mesh grille and slim xenon headlamps creating a strong road presence.

The strong, muscular lower half of the car is contrasted with the slim and graceful quality of the roofline, which takes inspiration from the original 1968 XJ saloon. The wrap-around rear screen reduces the visual weight of the pillars, and gives the impression of an exotic 'floating' roof.

And the new Jaguar XJ doesn't just look sleek and streamlined: it is, alongside the XF, the most aerodynamic Jaguar ever. The car has a drag coefficient (Cd) of 0.29, and, equally importantly, outstanding high-speed stability.

A key factor in achieving this highly efficient aerodynamic performance was the extensive use of Computational Fluid Dynamics (CFD) to refine the shape long before the car ever saw a wind tunnel. Taking the process pioneered on the XF programme to a new level of sophistication, more than 400 detailed CFD studies were performed during the initial design phase.

Every area of the new Jaguar XJ - from the outer skin to the composite undertray to the fine grille meshes of the cooling system - was optimised using this process. Key areas included the profile of the rear decklid, which was engineered to ensure that the airflow was controlled without the need for a spoiler. As well as reduced drag and impressively low wind noise, the overall shape achieves aerodynamic loads that are carefully balanced between front and rear axles to ensure optimum handling balance and high-speed stability.

Dramatic LED lights
The rear end is notable for its pure, sculpted shape, with a conscious absence of unnecessary ornamentation. The sheet metal of the rear panel retains its pure form, with a single leaping Jaguar motif making a strong, confident statement. The LED light clusters wrap stylishly over the rear wings, and feature three dramatic red, vertical strips.

Architectural interior design
The overriding impression from the interior is a sense of personal space, a feeling enhanced by the clean, simple form of the leather-wrapped instrument panel sitting low across the vehicle. At the sides of the cabin, a bold architectural wood veneer sweeps forward from the doors to meet at the front of the car, emphasising the new Jaguar XJ's powerful, dynamic character. This linear, modern use of wood helps to create a truly welcoming environment.

The panoramic glass roof has been from the outset an integral part of the design concept of the all-new Jaguar XJ. It enables a lower, more streamlined roofline, and also dramatically enhances the feeling of light and space within the car. The roof's opening mechanism slides the glass upwards and outwards, so that headroom is never compromised. A dark tint and reflective coating prevent the interior from overheating under strong sunlight, while twin electric blinds provide another level of privacy and sun screening.

THE TECHNOLOGY
In keeping with its position as the ultimate Jaguar saloon, the all-new Jaguar XJ pioneers the use of advanced new technologies, driver displays and infotainment systems that set an exciting new benchmark within its segment.

As the driver is greeted by the signature Jaguar 'handshake' - the circular knurled aluminium rotary control of the JaguarDrive Selector™ rising into the driver's palm - stylish 3D animations materialise in the virtual instrument cluster and on the central Touch-screen, giving an immediate signal that the new Jaguar XJ takes a revolutionary approach to the way information is displayed in the vehicle.

Sophisticated virtual instrumentation
There is no physical instrument cluster display in the all-new Jaguar XJ. Instead, a 12.3-inch high-definition screen, which uses sophisticated - and beautifully detailed - virtual instruments, provides all of the functions performed by traditional dials. Jaguar's designers have also taken advantage of the freedom provided by virtual instrumentation to help prioritise the most useful information as well as creating a real sense of theatre for the driver.

As the XJ starts, three virtual dials build before your eyes: the centre dial houses a speedometer, flanked on the right by a rev counter and on the left by an information window with fuel and temperature gauges.

To maximise clarity, the display employs a 'spotlight' effect to highlight the areas showing the most important information, such as the current speed or engine revs. When required - for example, if fuel is running low, or the driver is selecting a radio station - the rev counter fades away to be temporarily replaced by the required warning message or menu.

The prioritisation goes to another level when the driver who is looking for even more sporting performance and handling selects the XJ's Dynamic mode. In this case, the dials assume a sporting red hue and feature a bold gear position indicator which glows red as you reach the rev limiter.

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.

The new Jaguar XF is already acclaimed as a key element in the revitalization of the Jaguar brand, with its new generation of beautiful fast cars. But now the car that defines Jaguar sporting luxury is even better, with major powertrain changes and a wider range of models - including a stunning new, supercharged Jaguar XFR.

The 2010 model year Jaguar XF features all-new 5.0-liter direct-injection V8 engines. There are also significant trim and specification changes - including many new features unique to the new XFR - and the introduction of a new Portfolio derivative.

The Jaguar XF was soon recognized as a dramatic expression of a bold new Jaguar design language. It also soon became apparent that here was a car where the driving experience exceeded the expectations created by the striking appearance. Now, the new XFR takes this driving experience to new levels, shifting the balance even further towards dynamic performance while still retaining the Jaguar XF's core values as a refined and luxurious sports sedan. Power comes from an all-new 5.0-liter direct-injection supercharged V8 engine delivering 510bhp and 461lb-ft of torque. Immediately recognizable thanks to unique new 20-inch wheels, a new front end design with revised chrome air intakes, 'Supercharged' hood louvres, four polished exhaust tailpipes, an aerodynamically functional rear spoiler and side sills, the new XFR also sports discreet 'R' badging.

The attributes that marked out the Jaguar XF at launch are still very much new and in the public eye. The four-door XF has the visual excitement of a coupe, but room inside for five adults to enjoy an interior wholly contemporary in style yet uniquely Jaguar.

Simplicity and clever use of space are key to the Jaguar XF's interior design and this is unchanged in the new generation. For the driver, this is centered on the compact packaging of the JaguarDrive Selector™ transmission interface. The beautiful cast alloy Selector has already gained recognition for its part in the distinctive XF 'welcoming handshake'; a sequence in which the illuminated stop/start button pulsates like a heartbeat until pressed, when the JaguarDrive Selector™ rises into the driver's hand and the rotating fascia vents silently open.

Features such as this have already attracted more than 30,000 customers to the new Jaguar XF - and now, in many instances, they have been enhanced even further. The combination of aluminum dashboard, satin or gloss wood veneers, tailored instrument and door panels with twin-needle stitching as standard, plus Phosphor Blue halo illumination and interior mood lighting, set the Jaguar XF's cabin as far apart from its competitors as its exterior styling.

The new engines are Jaguar's most efficient ever, and they deliver power and performance at a higher level across the board. In the case of the supercharged engine, compared to the 4.2-liter V8, power has increased by a remarkable 23 percent and torque by 12 percent.

The result in the new Jaguar XFR is a 0-60mph sprint time of just 4.7 seconds (0-100kph in 4.9 seconds). More relevant in everyday driving, an excellent indicator of XFR's great flexibility is the time it takes to accelerate from 50-70mph - just 1.9 seconds.

The comparisons for the naturally aspirated engine are equally impressive. Power is increased by 29 percent and torque by 25 percent. The benchmark 0-60mph acceleration time is 5.5 seconds (0-100kph in 5.7 seconds) - some 0.8 seconds quicker than the 4.2 Jaguar XF.
