First customer deliveries from March 2009, dependent on market and model
INTRODUCTION The 2010 XK and XKR “Built in the tradition of great grand tourers, with state-of-the-art engineering, aerospace-inspired construction and outstanding driving dynamics, the new XK is the latest in a long line of legendary performance Jaguars.” Mike O’Driscoll, Managing Director, Jaguar Cars
The Jaguar sports car experience moves on to a new level in 2009 with the introduction of a new generation of the XK and XKR coupe and convertible.
With all-new V8 engines delivering more power and performance with greater efficiency, even more dramatic looks, interior enhancements, advanced lightweight aluminium body structure and a wider range of models, the new XK and XKR build on 60 years of legendary performance to deliver the best of everything Jaguar. Designated 2010 model year but – dependent on model and market – available from as early as March 2009, the new XK range not only stands out from the crowd, it stands apart.
The combined efforts of Jaguar’s designers and engineers have produced a sports car that utilises advanced technologies at a higher level than ever before. The benefits of the XK’s lightweight but stiff and strong chassis 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.
The AJ-V8 Gen III engines are the most advanced and efficient Jaguar has ever produced. They deliver significantly more power and torque than the previous generation of engines: 510PS and 625Nm in the new supercharged XKR and 385PS and 515Nm in the XK models.
With the introduction of these all-new 5.0-litre direct-injection V8 engines comes a new level of performance for the XK, with improved acceleration from standstill and stunning in-gear acceleration times. All models are electronically limited to a maximum speed of 155mph (250kph), but the 0-60mph sprint for naturally aspirated coupe models is now 5.2 seconds (previously 5.9 seconds), while for the supercharged XKR coupe, 0-60mph is 4.6 seconds (previously 4.9 seconds).
In-gear times are equally impressive, with the naturally aspirated XK accelerating from 50-70mph in just 2.5 seconds, while the supercharged XKR completes the same sprint in just 1.9 seconds.
And yet thanks to a combination of excellent powertrain efficiency and the XK’s advanced lightweight body architecture, all XKs offer strong fuel economy and impressive CO2 emissions ratings. Fuel economy is comparable to the previous generation of XK – despite the significant increases in power and performance – and CO2 emissions from each engine are better than the out-going versions. “With an all-new, supercharged AJ-V8 engine and dramatic new looks, the new XKR has all the performance, power and panache that you expect in the ultimate sporting Jaguar.” Mike O’Driscoll, Managing Director, Jaguar Cars
Allowing the engines to optimise their power is one of the most sophisticated transmissions available. 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™, which is new for the 2010 Model Year XK, the transmission is now paired with an advanced electronic differential on the XKR model. This ensures the supercharged car accelerates even faster, handles even more precisely and sets new standards of dynamic control.
There are three core models in the new XK range: the XK, the highly equipped XK Portfolio and the supercharged XKR, each with its own sporting character. In addition to the many changes under the skin, the new XKs are visually different to the previous generation. Each still looks just like a Jaguar should look – seductive, powerful and elegant – but all models, coupe and convertible, introduce revised exterior styling that underlines Jaguar’s contemporary thinking on design.
Inside, quality levels are raised even further with new interior trim and finishes that demonstrate Jaguar’s craftsmanship, plus even more comprehensive specification. The driver is the centre of attention, with exciting new ideas, including the acclaimed JaguarDrive Selector™, Adaptive Dynamics (the latest in computer-controlled suspension) with Active Differential Control and comfort features such as heated and cooled seats – taking the driving experience of the new XK range to even higher levels of luxury alongside the improved performance.
“The new XK delivers more power, more performance and more technology – without compromise. It moves the Jaguar sports car experience on to a whole new level.” Mick Mohan, Director, Jaguar Programmes
THE NEW 2010 XK AND XKR IN DETAIL
The new XK 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 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 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 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 XKR, 0-60mph is reduced to 4.6 seconds from 4.9 (and 0-100kph to 4.8 seconds from 5.2).
The supercharged XKR is also impressively efficient, with combined fuel economy of 23.0mpg and a CO2 rating of 292g/km – an improvement over the previous 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.
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.
Design Director Ian Callum outlines new design features on the XK range: “The current XK was the first car to signify a new generation of Jaguars – cars that have honed our image every bit as successfully as the original XK120 or E-type. Now the new XK range reinforces that message. The cars’ visual agility and beautiful lines have been enhanced with a distinctive new front end, rear lights and revised body styling that gives every model even more presence.”
The exterior changes for the naturally aspirated XK models and the supercharged 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 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 XKR comes with a new lower rear valance that is finished in body colour and a revised tailpipe design, further emphasising its sporting performance.
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 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 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 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 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.
Mike Cross, Chief Engineer, Vehicle Integrity explains the benefits of this advanced body architecture: “Lightness benefits agility, and agility with high performance defines the exhilarating yet refined nature of the Jaguar XK. It accelerates harder, stops more quickly and handles with true precision – setting new standards of dynamic excellence.”
The most advanced Jaguar V8 engines ever New AJ-V8 Gen III engines in brief - All-new direct-injection engines are much more powerful, compact and efficient
- 510PS, 625Nm, 292g/km CO2, 23.0mpg (12.3 l/100km) combined fuel economy (the supercharged Gen III R)
- 385PS, 515Nm, 264g/km CO2, 25.2mpg (11.2 l/100km) combined fuel economy (the naturally aspirated Gen III)
- Conforms to EU 5 and US ULEV2 emissions regulations - High efficiency, sixth-generation twin vortex supercharger (TVS) on XKR - Central spray-guided direct-injection increases efficiency and torque
- Torque-actuated variable camshaft timing on all four camshafts for improved response and efficiency
- Cam profile switching in naturally aspirated engine
- Variable-geometry inlet manifold on naturally aspirated engine further increases low and high-end torque
- Low-friction design optimises fuel consumption
- 15,000-mile service intervals
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.
Commenting on the new engine range, Ron Lee, Powertrain Group Chief Engineer, said: “We set ourselves the challenge of developing an all-new V8 engine series that improved on the performance and the refinement of the excellent 4.2-litre, with comparable fuel economy and improved emissions. We have achieved that with the AJ-V8 Gen III – a superbly responsive power unit of unsurpassed efficiency.”
Jaguar’s all-new petrol V8s have been designed using the expertise of powertrain engineers at Jaguar’s product development centre at Whitley, Coventry, UK. Malcolm Sandford, Engine Group Chief Engineer, explains the concept behind the project: “The emphasis was on delivering efficiency, superior dynamic response and highly accessible low-end torque suited to real-world driving, without compromising power at higher engine speeds.”
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.
Summarising this achievement, Director, Jaguar Programmes, Mick Mohan, said: “These engines have been engineered by our 800-strong powertrain team for the next generation of Jaguar cars. They deliver fantastic straight-line performance and response that is second to none. The combination of power, refinement and driveability is what our customers expect of a Jaguar: they are smooth around town, but when you want to drive quickly, the engines are hugely responsive and deliver that classic, Jaguar sound quality.”
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 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 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 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.
Driving Dynamics “The XK has always been an exceptional sports GT; now with huge reserves of power and torque, the XKR sets new standards of dynamic balance, succeeding in being both potent and rewarding yet balanced and accessible at the same time.” Mike Cross, Chief Engineer, Vehicle Integrity
The new ‘handshake’ of the JaguarDrive Selector™ is a subtle reminder of the new XK’s further enhanced sporting character and superb dynamics, which combine to deliver a driving experience that is exceptionally exciting and rewarding. The latest generation of Adaptive Dynamics replaces Jaguar’s proven Computer Active Technology Suspension (CATS) with an even more sophisticated solution. Active damper tuning systems remove many of the compromises of a passive damping system – which must make a single choice between softer damping for a comfortable ride and firmer damping for more tautly controlled handling. CATS overcame that compromise with automatically switchable damping modes, adapting to the road and how the car was driven. But where CATS only offered two settings: ‘soft’ and ‘firm’, the new Adaptive Damping System in effect provides a continuously variable damping strategy between wide extremes, benefitting ride comfort, ultimate control handling and grip.
Its three primary functions are to control body vertical movement, roll rate and pitch rate. One hundred times a second, Adaptive Damping performs three critical functions: firstly, it analyses induced body motions and sets each damper to an appropriate level in order to maintain a constant and level body attitude – maximising control without compromising ride. Second, it also predicts the roll rate due to steering inputs and selectively increases damping forces to reduce roll – improving handling feel and driver confidence. And third, Adaptive Damping analyses 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 quality 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’ on uneven roads by varying damping to move any wheel out of its natural bouncing frequency.
From the cabin, the JaguarDrive Control™ interface allows the driver to interact with Adaptive Dynamics by selecting modes for different driving conditions and moods. In Dynamic Mode, Adaptive Dynamics increases body control for a sportier feel. Dynamic Mode also interacts with the engine ECU to give a more responsive accelerator pedal reaction and quicker gearshift responses.
Winter Mode was introduced on the XF and now makes its first appearance in the XK range, adding another element of dynamic subtlety. Where Dynamic Mode offers a more sporty feel, Winter Mode offers a more damped accelerator pedal response for progressive control in slippery conditions, with bespoke shift settings that delay and soften gearshifts, again for better control with low grip. In keeping with its additional power and performance, the new XKR offers the most sophisticated dynamic control of all, with Active Differential Control and Adaptive Dynamics. The subtle control strategies of these functions can be managed through the JaguarDrive Control™, which allows the driver to change the settings of the Adaptive Dynamics system, which then works in tandem with the Active Differential Control (ADC) – an electronically controlled alternative to the traditional mechanical differential.
Active Differential Control for precise driving ADC is fully automatic and can vary its locking torque (and therefore the proportion of torque sent to each driven wheel) depending on surface conditions and power applied. Its subtle control strategies optimise traction at each wheel, improving acceleration on low-grip surfaces but also potentially improving stability when required.
Working with other systems such as traction control and the ABS braking function, ADC can significantly improve overall vehicle performance, and provide more precise driving feel.
While the less powerful XK models do not adopt the Active Differential Control of the XKR, they do still utilise a new upgraded mechanical differential, which delivers outstanding levels of grip and stability under power.
The Dynamic Stability Control system for the new XK range has bespoke tuning and offers four driver-selectable modes, Normal, Winter, Trac DSC and DSC OFF on all models. Normal mode is ideal for everyday driving and is the default setting activated automatically on starting. The Winter mode is designed to improve drivability and confidence in more slippery conditions. Trac DSC mode is a sportier setting allowing the experienced driver fully to exploit the car’s performance and enjoy greater involvement in controlling it. DSC OFF allows the driver (where circumstances are appropriate) to switch the system’s electronic protection off completely, by pushing the DSC control button for 10 seconds.
User-friendly technology and driving aids
The new XK and XKR, in both coupé and convertible form, offer a number of other driver aids that exploit the latest advanced technology. Staying faithful to its well-established principles, Jaguar uses these technologies to empower, not overpower the user – enhancing enjoyment rather than risking high-technology overkill.
Among the new XK range’s practical features are intelligent front lighting incorporating bi-xenon automatic headlamps with power wash; dynamic headlamp levelling; corner lights that are activated by the direction indicators to improve visibility while cornering; and the option of Active Front Lighting.
Standard equipment across the new XK range also includes air sensors to optimise cabin air quality through the climate control system, keyless start, cruise control, electro-chromatic fold-back exterior mirrors, and front and rear Park Assist.
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.
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 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 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 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 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.
Ease of ownership
For all, their performance and luxury, the new XK range is designed to be remarkably easy to live with. Both naturally aspirated and supercharged versions of the new 5.0-litre AJ-V8 Gen III engine offer extended service intervals – now at one year or 15,000 rather than 10,000 miles. All new XKs now feature oil quality and brake pad wear indicators, allowing those critical areas to be easily monitored on a regular basis by the driver. And in the event of an accident, bolt-on front and rear sections help to minimise repair costs.
“The XK has always been an exceptional sports car. Now, it has evolved into something even more exhilarating, combining Jaguar’s legendary performance, new advanced technologies and crafted luxury to create a sports car without parallel.” Russ Varney, Chief Programme Engineer, XK Series

REVEALS ALL-NEW XK CONVERTIBLE
All-new 2007 XK Convertible will go on sale in North America alongside the recently announced XK Coupe in spring 2006
Following the World Premiere of the XK Coupe, Jaguar is proud to announce that it will be joined by the all-new XK convertible.
From the outset Jaguar knew it needed to create a convertible version of the XK and designed and developed it in parallel with the Coupe. The XK Convertible uses the same advanced aluminum body structure technology to achieve excellent body rigidity and torsional stiffness while minimizing weight: at just 3759lbs the new Convertible is one of the lightest cars in its competitive set.
A 300bhp (SAE), 4.2-liter V8 engine and Jaguar Sequential Shift steering-wheel-mounted gear change controls ensure rapid performance of 0-60mph in just 6.0 seconds (0-100kmh in 6.3 seconds) and an electronically limited top speed of 155mph (250kmh)*.
The luxurious triple-lined, fabric roof - which can be powered up or down in less than 18 seconds when retracted it stows fully out of sight beneath an aluminum tonneau cover. A roll-over protection system comprising two 'hidden' aluminum hoops that deploy in the event of an incident is standard on all XK Convertibles.
"The all-new XK was designed from the outset to be a beautiful convertible. It is a statement of confident Jaguar design, elegant as well as powerful and with the performance and driving dynamics to match its looks", commented Jaguar Design Director, Ian Callum.
The XK Convertible will be available from spring 2006. Full details of the car and pricing will be announced later this year.
The XK Convertible is manufactured and assembled in a state-of-the-art production facility at Jaguar's Castle Bromwich plant in the West Midlands region of the United Kingdom.

THE ALL-NEW JAGUAR XK PREMIERES
WORLD - FIRST DEPLOYABLE BONNET SYSTEM
• Jaguar Pyrotechnic Pedestrian Deployable Bonnet is a world first
• System operates in less time than it takes to blink
• Advanced Sensing system can distinguish between different impacts
• Over 120 man years dedicated to system development
• Bonnet is raised in around 30 milliseconds using forces up to 50 times the force of gravity
In an era of safety conscious motoring, Jaguar has managed to combine beautiful, fast sports car design with the latest pedestrian impact technology to create a world first with the all-new XK. Today at the Frankfurt motorshow Jaguar engineers premiered the Pyrotechnic Pedestrian Deployable Bonnet System (PDBS) a state-of-the-art advanced safety feature.
Within the 'blink of an eye' In the unfortunate event of a pedestrian impact, the deployable bonnet on the new XK automatically ‘pops’ up a few inches, to create a cushioning effect between the engine and the bonnet. This helps to isolate the pedestrian from hard points in the engine compartment - and takes place in less than a tenth of the time it takes to blink an eye.
Jaguar is one of the first manufacturers to meet Phase One of new European safety legislation using an active deployable bonnet system. The new standards are designed to help mitigate the severity of injuries to pedestrians in the event of a collision with a car.
Legislation in the European market requires manufacturers to commit to a two-phase introduction of a range of active and passive safety improvements on all new cars to improve the protection of pedestrians in case of accident.
'The Jaguar design team embraced the idea of using a deployable bonnet when it was first considered during early concept discussions on the new XK. This clever feature saves between 50 and 65mm in height off the bonnet surface and a similar amount off the roofline, allowing the design team to maintain a very low, sleek Jaguar sports car profile on the new XK.' said Ian Callum, Jaguar Cars Design Director.
The Jaguar Pyrotechnic Pedestrian Deployable Bonnet provides an innovative solution to these legislative requirements whilst ensuring that the sleek lines that customers expect from Jaguar sports cars can be retained. The active system fitted to the all-new XK is complemented by a passive bumper system, the design of which helps to mitigate leg injury through the use of crushable foam and plastic covering. An advanced sensing system is mounted in the front bumper to help discriminate between a pedestrian collision and any other possible front-end collisions. The speed of the sensing time in the system is around one tenth of the time it takes to blink an eye.
Phil Hodgkinson Jaguar Programmes Director said: 'I take technology development at our product development centres very seriously and I am proud to be working with Jaguar engineers that can deliver this kind of safety system, which we believe to be a world-first. The fact that it also allows us to stay true to Ian Callum's core Jaguar design values is equally satisfying.'
The complex system has been extensively researched across wide-ranging scenarios, using 120 man-years and thousands of computer simulations, as well as tested in practice at Jaguar’s Engineering Centre at Whitley in Coventry, England. While all pedestrian impact research has been carried out using virtual tools, analysis of previous 'real world' incidents has played an important part in the development process.
One of the impressive points about the new XK's pyrotechnic deployable bonnet system is that it can lift the bonnet (which weighs 18kg) in around 30 milliseconds, which requires an acceleration rate of about 50 times the force of gravity (50g).
Physical research carried out by the Jaguar development team has included investigation of various impacts including inanimate objects such as motorway cones. This is a vital part of the process to allow the system to differentiate a person from other impacts that can be experienced in day-to-day driving.
The Jaguar pyrotechnic pedestrian deployable bonnet system normally operates at vehicle speeds where it provides the most benefit and is automatically disabled outside of this speed range. The system is completely separate from any other crash protection system on the vehicle, including airbags.
'The Pyrotechnic Pedestrian Deployable Bonnet in the all-new XK is a leading safety technology that goes hand in hand with an advanced Jaguar sports car, sitting alongside a beautifully crafted luxury interior, aluminium technology and scintillating, dynamic performance.' said Russ Varney, Chief Program Engineer for the XK series.

THE ALL-NEW JAGUAR XK IS
UNVEILED AT THE FRANKFURT AUTO SHOW
Jaguar is proud to announce a new era in its sports car lineage – the all-new XK. Like all great Jaguar sports cars, the focus of the all-new XK is firmly on the future, while acknowledging the marque’s rich history. It heralds a new era for Jaguar in terms of both design and engineering, and it is the most technically advanced Jaguar ever built.
The all-new XK continues the Jaguar tradition of beautiful, powerful, ground-breaking sports cars, but behind its stunning looks, it bristles with practical, intuitive, modern technology, clearly focussed on enhancing the driving experience. It delivers significant improvements in performance, dynamics, safety, exterior and interior design and equipment, and product quality. When it is launched in early 2006, this first of the next generation of Jaguars will become the sporting flagship of the Jaguar brand.
By starting with a blank canvas, Jaguar was able to make use of the latest aerospace technologies alongside more traditional Jaguar skills to create a luxurious, powerful, highly advanced sports car. A major key to the all-new XK’s character is Jaguar’s industry-leading aluminium monocoque body structure, introduced with the latest XJ saloons.
With this unique high-tech construction method, the all-new XK’s bodyshell is 31 percent stiffer than the previous XK’s and significantly offers a 10 percent improvement in power to weight ratio. The all-new XK is up to 90 percent stiffer and 180kg lighter than key rivals, with a kerb weight of just 1595kg.
In the words of Jaguar's Chief Engineer Mike Cross, in charge of the all-new XK’s vehicle dynamics, "What the team has looked to engineer is a sports car with true all-round ability. That means it must be fast, outstandingly agile, and truly exciting to drive. It has to go quickly, stop quickly, and do everything in between in the way a Jaguar should. Yet it’s also a rational choice – the all-new XK will deliver a balance of superb driving dynamics and comfort that is the epitome of sophisticated sporting luxury."

*Manufacturer provisional test figures DESIGN
You only have to look at the all-new XK to know that this car is a giant leap forwards. The handsome, powerful looks are clearly a continuation of the style of the Advanced Lightweight Coupe concept first unveiled at the Detroit Auto Show in January 2005.
The use of beautiful lines and clean surfaces was crucial in defining the all-new XK’s more sporting character. In Jaguar design director Ian Callum’s words, "The fundamental values of Jaguar design do not change – not even since Sir William Lyons created the first Jaguar all those years ago. The entire design team worked with those values as we looked to create a car with clean lines, a purposeful stance and exquisite proportions. We took influences from our heritage and evolved them to produce a car that is beautiful, visually fast yet undeniably modern; just as Sir William's own designs were in their day."
In one respect the all-new XK arguably has more in common with earlier cars like the original XKs and the C, D and E-types than it does with the most recent XK, and that is the way in which the shape wraps more tightly around the mechanical underpinnings. The way the well-toned skin stretches tautly over the structure is timelessly modern, sophisticated, and easy on the eye.
The all-new XK is visibly more assertive and sporting than the model it replaces – a future classic in its own right. In true Jaguar tradition the all-new XK is also elegant and understated. It has classic, ground-hugging coupe proportions, with a long bonnet, steeply raked windscreen and rear window, arch-filling wheels, and minimal overhangs. The front-wing power vents are a new Jaguar styling signature; the distinctive oval grille opening, prominent bonnet power-bulge and practicality-enhancing rear liftback door all echo the E-type; while details like the sweeping front and rear light shapes and powerful stance establish Jaguar sports car design firmly in the 21st century.
Inside – as outside – the all-new XK features clean, simple, modern lines. It uses traditional craftsmanship and contemporary luxury materials like finely stitched leather, contrasting with a choice of more high-tech trim surfaces including metallic finishes. The layout is driver-focussed and sporting, with excellent ergonomics and body-hugging seats, set low against the high waistline to give a strong ‘cockpit’ feel. With a longer wheelbase, wider track and taller roofline, the 2+2 layout has more interior space than the XK that it replaces. Indeed this flagship coupe leads its class in terms of front legroom and shoulder room and boasts a 20mm increase in front-seat headroom over the previous Jaguar XK coupe.
Inside the cabin the minimalist instrument cluster houses two prominent round dials either side of an advanced high-resolution colour display based on thin-film transistor technology. This display is split into several zones showing vital information such as gear selection, cruise control information, low tyre pressure warnings and satellite navigation instructions, depending on market. A centrally mounted 7-inch touch-screen allows intuitive selection of climate, audio, navigation and telephone settings.
Amongst the user-friendly advanced technologies in the all-new XK is the Jaguar Smart Key System, which provides keyless start with a push-button starter, and also optional keyless entry simply by carrying the Jaguar Smart Key in your pocket or bag.
LIGHTWEIGHT VEHICLE TECHNOLOGY
While the first striking impression of the all-new XK is delivered by its looks, its real essence is in what lies under the skin. The most far-reaching engineering feature in the all-new XK is its use of Jaguar’s Lightweight Vehicle Technology, the all-aluminium architecture that was introduced with the latest generation XJ saloon.
It is unique in the industry as a complete aluminium monocoque body structure, as distinct from an aluminium spaceframe with separate aluminium exterior panels. Developed from aircraft industry methods, where strength and light weight are critical, Jaguar’s manufacturing process produces a massively strong but very light structure that is both riveted and epoxy-bonded.
The new XK takes the Lightweight Vehicle concept a step further with extended use of aluminium castings and extrusions as well as pressed aluminium panels. Its remarkable strength and light weight come from both the way the bodyshell is constructed and the use of new jointing technologies developed by Jaguar and its suppliers.
The all-aluminium rear liftback door is strong, light and simple to operate. It pivots on two hinges ensuring the edge of the liftback moves away from the operator’s head as the lid is raised. It also provides excellent rear visibility – rare in the sports coupe field.
Beyond the exceptional body integrity and built-in deformation zones, the all-new XK is also available with a host of other safety solutions for protecting pedestrians as well as car occupants. Those include the shape and construction of the bumpers and bonnet, plus a completely new technology, the pedestrian deployable bonnet. This is deployed upwards away from its rear edge, in milliseconds, in the event of a pedestrian impact. This forms a safety zone between the bonnet and the engine and other under-bonnet hard areas to reduce significantly the potential for injuries.
With lower weight and higher strength, Lightweight Vehicle Technology is the starting point for improved performance, safety, refinement, economy, emissions performance and driving dynamics. Russ Varney, Chief Programme Engineer, Sports Range, explains how a 'no compromise' mentality was applied when it came to engineering the ultimate grand tourer:
"As a team we worked from day one to ensure that the all-new XK delivered on every target set for the vehicle. In the case of the aluminium monocoque body structure, it delivers great advantages in terms of weight and strength and we were determined to utilise those benefits to produce a sports car with a blend of stunning vehicle dynamics and outstanding comfort."
From launch the all-new XK will be powered by Jaguar’s renowned naturally aspirated 4.2-litre V8 engine which produces 300bhp SAE (298 PS EEC). This compact, lightweight engine is based on that fitted to the latest generation XJ saloon and has undergone significant development compared with the engine used in the previous XK, including new fuel-injection technology. The latest 4.2-litre engine satisfies Euro 4 emissions requirements as well as stringent US emissions regulations.
The 4.2-litre V8 develops maximum torque of 303 lb ft (411Nm) EEC at 4,100rpm. Again, the spread of torque is an important ingredient in the XK’s effortlessly sporty character, and this engine delivers more than 85% of torque all the way from 2,000 to 6,000rpm. Yet it still offers fine fuel economy and low emissions figures, with a drop in CO2 emissions of 6 percent.*
The naturally aspirated 4.2-litre V8 XK coupe has an electronically limited maximum speed of 155mph and a 0-60mph time of 5.9 seconds, plus instant throttle response and broad flexibility for punchy performance across the range. With the all-new XK’s weight savings, the new naturally aspirated 4.2’s standing quarter-mile time of 14.4 seconds is less than half a second off the pace of the previous supercharged 4.2 XKR.*
For the first time in a Jaguar, drivers will be able to use steering wheel-mounted paddles to change gear with the new Jaguar Sequential Shift transmission. In either Drive or Sport Manual modes, very fast gear shifts are achieved by combining the use of one-touch paddles with an automatic blip of the throttle from the drive-by-wire engine management system during downshifts. Thanks to this positive torque enhancement control, the shifts are faster and more responsive than before regardless of the mode the driver has selected.
The XK’s six-speed transmission introduces a new generation of automatic gearshift for Jaguar, replacing the familiar ‘J’ gate with the new Jaguar Sequential Shift system with Park, Reverse, Neutral, Drive and Sport modes. The fully automatic Drive mode adapts to individual driving styles, while a Sport Auto mode can also be selected. This offers an even more responsive fully automatic shift strategy, also utilising the automatic blip of the throttle to maintain ultra-smooth gear shifts.
*Manufacturer provisional test figures
The all-new XK has a completely new, high-performance braking system, tested extensively over many hundreds of laps at the gruelling Nürburgring test track in Germany, where Jaguar has a dedicated research facility. The result is greater braking power and more responsive feedback to the enthusiastic driver.
Larger, ventilated discs contribute to better pedal feel, optimum stopping distances and resist fade during extended hard use. The braking system also includes four-channel ABS, Electronic Brake Force Distribution, Hydraulic Brake Assist to increase brake pressure during an emergency stop, and Jaguar’s Electronic Park Brake function.
Unlike conventional digital ABS systems used on many cars, the all-new XK’s ABS system can vary the brake pressure at each wheel using analogue valves in the hydraulic control unit. This gives more refinement to the hydraulic pressure control and allows drivers to benefit from increased steering input during heavy braking.
The all-new XK’s Servotronic 2 steering is adapted for a sports car from the XJ saloon, to give easy low-speed manoeuvring with optimum high-speed feedback under all conditions.
Beyond the exceptional new pedestrian impact safety systems, the XK also includes a host of other safety features. These include the option of a Tyre Pressure Monitoring System and run-flat tyres, Jaguar’s Protec dynamic headrest system to protect against whiplash injuries, Forward Alert which uses the optional Adaptive Cruise Control’s forward-facing sensors to scan the road ahead 10 times every second to warn of a potential collision, and the new switchable Dynamic Stability Control with Traction Control System (Trac DSC).
A new active front lighting system is also offered as an option on the XK, enhancing the bi-xenon intelligent lighting that is standard on the car. This feature provides enhanced visibility in the dark during higher speed cornering by swivelling the dipped beam lens depending on road speed and the angle at which the steering wheel is turned.
Like any of the great Jaguar sports cars of the past fifty years and more, the all-new XK pushes the boundaries of sports motoring. It is the most technically advanced Jaguar ever, and undoubtedly one of the most beautiful. It is lighter, faster and better equipped than the model it replaces, with substantial improvements in performance, driving dynamics, braking, safety and economy.
Being a Jaguar, it combines the comfort, style and craftsmanship of a luxuriously equipped grand tourer with the driving dynamics of a true sports car. It captures the unique joy of driving that Jaguar drivers expect. In the finest Jaguar tradition, it is a truly beautiful, fast car, the product of advanced engineering and fine craftsmanship. It offers style, comfort and luxury. But it also keeps true to what sports car motoring is about – and that is the undiluted thrill of driving.

UNVEILS ALL-NEW XK SPORTS CAR
Britain's newest and most beautiful sports car is coming to North America. Jaguar North America today reveals details of its eagerly anticipated new sports car – the all-new 2007 Jaguar XK.
Making its world premiere next month at the Frankfurt International Auto Show in Germany, the all-new Jaguar XK will go on sale in North America next spring as a 2007 model year product.
The all-new Jaguar XK is the first of a new generation of cars that reflect the best of everything that Jaguar is associated with – from gorgeous, contemporary design to renowned craftsmanship and quality, alongside the latest driver-focused technologies – and, of course, exhilarating performance.
Light and agile, the all-new Jaguar XK accelerates faster, stops quicker than the previous generation, steel-bodied XK8 and has exceptional dynamic abilities, as Jaguar's Chief Engineer Mike Cross, explains: "The XK may be the epitome of sporting elegance but it is also a true driver's car in which we have managed to combine a very special balance of superb driving dynamics and comfort."
Traditional Jaguar craftsmanship elements have been retained on the all-new Jaguar XK, but it's the use of aerospace technologies that have resulted in the most technically advanced Jaguar production car ever created.
One of the key elements of the all-new Jaguar XK is the use of latest technologies including Jaguar’s industry-leading aluminum body structures and rivet bonding techniques, both recently introduced in the construction of Jaguar's full-size XJ sedan. Both techniques make the XJ sedan significantly lighter and stronger than its competitors, which benefits handling and fuel economy.
Jaguar design director Ian Callum describes the XK as having 'clean lines, a purposeful stance and exquisite proportions'.
"The fundamental values of Jaguar design do not change," explains Callum. "We took influences from our heritage and evolved them to produce a car that is beautiful, visually fast yet undeniably modern – just as Sir William Lyon's (Jaguar founder) own designs were in their day."
The all-new XK is manufactured and assembled in a state-of-the-art production facility at Jaguar's Castle Bromwich plant in the West Midlands region of the United Kingdom.
ALL-NEW JAGUAR XK AT A GLANCE
Jaguar XK 2+2 sports coupe
June 10 2005
During June Jaguar dealers in the UK were shown the new XK that is scheduled to make its debut at the Frankfurt Motor Show in September. The first deliveries will take place early in 2006. By all accounts the car will feature the 4.2 and 4.2 supercharged engines.
These photos show the finished car in all its glory without any camouflage. Whilst the front is similar to the Advanced lightweight coupe the rear shows a design feature reminiscent of the E type coupe, namely a tailgate. Obviously this will give easy access to the rear luggage area.
February 22 2005
ADVANCED LIGHTWEIGHT COUPE POINTS TO JAGUAR'S FUTURE Jaguar is using the North American auto show 'circuit' to gather key customer feedback on its stunning Advanced Lightweight Coupe concept. After its world debut at January's North American International Auto Show in Detroit, the Advanced Lightweight Coupe took center stage at this month's Chicago auto show. In March, it makes a stop at the New York International Auto Show. "The reaction from potential customers has been sensational. They tell us they want it, and want it now," says C.J. O'Donnell, Executive VP of Marketing, Sales and Communications, Jaguar North America.
Created by the Jaguar advanced design team in Coventry, England under the watchful eye of renowned Design Director, Ian Callum, the sensuous 2+2 show car features lightweight aluminum body architecture similar to the one pioneered with the new XJ sedan. "Auto shows provide us with invaluable feedback from literally thousands of potential customers. Everyone has a viewpoint on what they like or don't like about the car," explains Callum. Laid out in a classic 2+2 sports car format, the interior of the Advanced Lightweight Coupe is more spacious and better packaged than any previous Jaguar sports car. Rich, hand-stitched tan leather and aluminum inserts give the cabin a modern, contemporary feel. "The Advanced Lightweight Coupe represents the very essence of Jaguar, its heart and soul. If you want to know what lies ahead for us, what direction we will take - this is Jaguar's answer," said Joe Greenwell, Chairman and CEO, Jaguar Cars. "Its design is assertive and pure - a perfect symbol for our 21st century cars. And beneath that beautiful body lies the heart and soul of a true Jaguar," adds Greenwell.

ADVANCED LIGHTWEIGHT COUPE MAKES WORLD DEBUT AT NORTH AMERICAN INTERNATIONAL AUTO
Advanced Lightweight Coupe is not just a show car. It is a company personified.
Like the iconic Jaguar XK120s and E-types that preceded it, the Jaguar Advanced
Lightweight Coupe heralds a new generation of stunning sports coupes and saloons;
cars that will remain true to Jaguar’s illustrious past but more importantly will
see the company leaping confidently forward into the future.
The Advanced Lightweight Coupe is a physical expression of Ian Callum’s direction for the next generation of Jaguar cars which, like this 2+2 show car, will have purposeful and seductive exteriors that bring Jaguar design firmly into the 21st century. And with the lightweight aluminium body architecture technology that was introduced with the new XJ saloon, in production form the Advanced Lightweight Coupe would be as dynamic and agile as it is desirable.
“This company has had many ground-breaking moments,” says Joe Greenwell, Chairman and CEO, Jaguar Cars. “The XK120 was a ground-breaker and of course the E-type and XJ6 saloon in the 1960s helped to change the face of motoring. These were events in automotive design history that have stood the test of time and I would like to think that we will look back on the Advanced Lightweight Coupe as another of those moments in Jaguar’s lineage.”
Jaguar Cars Managing Director Bibiana Boerio concurs:
“This show car is a rallying call for Jaguar lovers the world over, who appreciate sporting luxury. We want them to know that we are committed to a product-led transformation of this company that will see us making Jaguars with great design and wonderful interiors that are fast, glamorous and evocative. A new Jaguar sports car is always an important event and we absolutely believe that the Advanced Lightweight Coupe demonstrates that the direction we are taking is the right one.”
Design Director Ian Callum’s vision for the next generation of Jaguars is clearly expressed in the Advanced Lightweight Coupe show car. Its exterior lines are beautiful yet powerful – a confident blend of curves highlighted by muscular detail, resulting in a car that could only be a Jaguar.
“I firmly believe that Jaguars should appear powerful as well as elegant,” Callum says. “Look back at the great cars from our past and you will see that they were as muscular and taut as they were subtle and curvaceous. That’s what confident Jaguar design is all about.”
This belief stems from Callum’s first sighting of the original Jaguar XJ6 saloon in the 1960s; an event that he describes as “the moment the penny dropped” when it came to his understanding of car design.
“As soon as I saw the XJ6 I realised what creating a beautiful car was all about,” he says. “It was a perfect example of what designers call proportion and stance, which simply means how a car sits on the road. The XJ6 was so structured and confident it was like nothing else – its wheels appeared huge, almost out of proportion to its body, and they were visually right at each corner of the car. It really looked as if it was hunkered down on the road.”
Those principles have remained with Callum ever since and played a pivotal role in the design of his previous Jaguar show cars, the R-Coupe and R-D6. Now the Advanced Lightweight Coupe continues that theme, but in an exhilarating sports car that has the visual agility to match its performance potential.
Echoing the lessons learnt from the XJ6, the show car’s distinctive stance and bold profile give it genuine visual dynamism – an effect that Callum describes as the car appearing to change shape in front of you.
The Advanced Lightweight Coupe’s distinctive tapering shape at both the front and rear means there appears to be no overhang beyond the wheels, giving the car a very exciting presence and a real sense of power and potency. When that is combined with beautiful surfaces that run across the entire bodywork you have the key ingredients for a sports car that gives a concise and clear statement about the look of future Jaguar models.
As Jaguar Cars Managing Director Bibiana Boerio explains:
“This car takes our coupe design onto another level. It is muscular without being over the top – a naturally honed athlete. Just like its predecessors, we believe the next generation of Jaguars should be different from anything else in the marketplace. We are not trying to copy our rivals because we have our own path to take. We know what that path is and we are showing the way.”
Creating a sports show car that conveys the remarkable heritage of Jaguar with integrity while projecting the marque forward into the future was not a simple challenge. Ian Callum and his design team passionately debated how the Advanced Lightweight Coupe would strike that balance before settling on this stunning design.
Every curve of the bodywork and rise and fall of each surface is deliberate, concise and calculated. There is no design for design’s sake on the car, no extraneous sculpture or unnecessary surfacing; a point that Callum believes will separate future Jaguars from other cars.
“Nothing is superfluous on this car,” he stresses. “If you point at any part of the bodywork it is there for a specific reason or because it simply can’t go any further in. We have produced a skin that is drawn taut across the chassis; one that covers the bare essentials underneath and nothing else – that’s how a sports car body should be formed.”
The car rides on unique 21-inch alloy wheels with custom-made Pirelli tyres, which sit below wide, flowing haunches. The rear haunch is of particular note, its prominent shoulder helping to exaggerate the size of the wheels relative to the body. With the visual mass of the cabin also drawn back towards the rear haunch the car appears to be moving forward even when it is standing still.
The grille on the show car is also of prime importance as an indicator for the look of future Jaguars. As a pure geometrical form it draws its inspiration from classic Jaguars of the past like the E-type. Additionally, features such as the polished aluminium gills reinforce the engineering integrity that is present in all Jaguars.
“When Jaguar’s revered aerodynamicist Malcolm Sayer created the E-type he didn’t sculpt that car, instead he devised that remarkable shape from pure geometry – it is a series of ellipses,” says Giles Taylor, Jaguar Senior Design Manager. “By designing the E-type that way he gave it a mechanical purity that we wanted to reflect in this car’s face. That meant the grille had to be perfectly symmetrical in both a horizontal and vertical plane, and by doing that we have made a focal point from which every line can stream backwards.”
Rising from the radiator grille, a prominent bulge in the hood runs to the base of the windscreen and invokes a notion of real power beneath the skin. From there the cabin flows back in a clean, spontaneous line to the car’s rear end which tapers sharply to a focal point of two, centrally-mounted tailpipes.
The headlights are a departure from the simple elliptical lenses on current Jaguars. Instead a more contemporary, angular design gives the Advanced Lightweight Coupe an edgy look and helps to draw your eye around the corner of the car to the new chrome gills that sit behind the front wheels. These would aid engine cooling and also improve aerodynamic flow to the rear.
In keeping with the understated and contemporary feel of Jaguar’s previous recent show cars, this car’s interior is restrained yet undeniably luxurious and welcoming. The task for the interior design team was to produce a cabin that wasn’t over-powering or fussy.
“We all agreed that our interiors should be clean, simple and straightforward,” says Ian Callum. “There is an honesty about the car’s interior which I really like.”
Laid out in a classic 2+2 sports car format, the car’s cabin is more spacious and better packaged than previous Jaguar coupes, with impressive headroom and multi-directional sports front seats and individual bucket seats in the rear. The interior is trimmed throughout in a tan leather which has visible stitching on the hides that line the doors and the dashboard. Aluminium inserts are spread throughout the car to act as jewellery that accentuates the contemporary feel of the cabin. Its focal point is the central dashboard console that houses an advanced Alpine telematics screen which provides user-feedback in the form of a ‘pulse’ when you touch the on-screen buttons.
The instrument binnacle has been designed to relate to the shape of the steering wheel and houses a high-resolution screen between its dials that provides the driver with a secondary source of infotainment and satellite-navigation information. Behind the steering wheel sit the gearshift levers that operate an automatic paddleshift transmission – the first time this technology has appeared on a Jaguar. The paddles are mounted to the wheel itself, rather than the steering column, to ensure that whatever angle the wheel is held at, the driver doesn’t have to take his concentration away from the road. Just the kind of touch you’d expect in what is, first and foremost, a driver’s car.
What if we let our minds wander for a moment? What if this show car was a road-going reality? Well, the Jaguar Advanced Lightweight Coupe would be the most potent 2+2 the company has ever created. Thanks to a technologically advanced aluminium architecture – which is around 40 percent lighter and 60 percent stiffer than a standard steel body – and renowned V8 powertrain assembly, the car would be capable of compelling performance, reaching 60mph from standstill in less than five seconds and breaking the 180mph mark at maximum velocity.
Yet it is not simply straightline speed that would make the car so notable. It would also demonstrate an agility that reaffirms Jaguar’s commitment to producing the best-handling sports coupes and saloons in the world.
“The Advanced Lightweight Coupe is the sort of Jaguar we want to build,” says Joe Greenwell, Chairman and CEO, Jaguar Cars. “But that means we must do much more than just come up with a beautiful design, we must have the tools in place to turn that creative spark into something tangible. What people should recognise is that we have the people in place to allow this to happen. The company’s engineering team is as strong as it has ever been and this new generation of engineers is all set to follow in the footsteps of great names from Jaguar’s past.
“Today’s team, with extraordinarily talented people such as Phil Hodgkinson, Jon Carling, Russ Varney and Mike Cross, will drive Jaguar’s product direction. These are the people who will take Ian Callum’s designs and ensure that the end products are as desirable as the concept cars that precede them.”
The engineering excellence that abounds at Jaguar is reflected in this car’s impressive technical specification. An aluminium chassis similar to that used in the new XJ saloon is constructed using many of the same advanced technologies. It is not just lightweight but also incredibly strong and stiff, which is of immense benefit to a car’s handling and ride as well as fuel economy and exhaust emissions. The lighter body also means responsiveness is improved whether you are talking in terms of steering feel, traction or power delivery. Jaguar’s V8 engines are admired as much for their impressive low-down torque as their peak power outputs and with a lighter aluminium body to propel, that torque is even more noticeable.
“The next generation of Jaguars will be remarkable drivers’ cars,” says Phil Hodgkinson, Director, Product Engineering. “Whether you want to relax behind the wheel on a long journey or head out simply for the pleasure of driving there will be no need to compromise. Our cars will be the perfect blend of performance and luxury.”
Jaguar’s array of intuitive technologies – features that make life easier for the driver, not more complicated – also sit easily with the Advanced Lightweight Coupe ethos. Dynamic aids such as Computer Active Technology Suspension work in conjunction with safety systems such as Adaptive Cruise Control and the Active Restraint Technology System – all features that Jaguar already has on its production cars.
And like Jaguar’s XJ and S-TYPE saloons, this car has an adjustable pedal box to ensure that drivers are seated in optimum comfort. As with all Jaguar’s technologies these systems operate discreetly, without intruding on the unparalleled Jaguar driving experience – they are there when you need them but never impose themselves.
In summary, the Advanced Lightweight Coupe is a beautiful, fast Jaguar that is true to the brand’s past and heralds an exciting future. It combines the talents of Ian Callum and his design team with brilliant engineering expertise – a combination that will ensure every upcoming Jaguar model delivers both dynamically and visually.
“This car is as clear a statement on the strength and confidence of the company as we could possibly make,” concludes Joe Greenwell, Chairman and CEO, Jaguar Cars. “Its design is assertive and pure – a perfect symbol for our 21st century cars – and beneath that beautiful body lies the heart and soul of a true Jaguar sports car.”
“The Advanced Lightweight Coupe marks a return to the core values of Jaguar,” says Bibiana Boerio, Managing Director, Jaguar Cars. “There is a determination in every department of this company to produce a new range of cars that provides the total Jaguar experience and this car is the first evidence of that determination.
“Aspirational and exclusive, with contemporary design and stunning performance, the Advanced Lightweight Coupe is conceived as a special car for special people. It represents the unique position that Jaguar holds in the market place – and even more it tells the world that we are set to make another bold leap forward. For Jaguar, the future begins now.”
