Adrian Hallmark, Global Brand Director, Jaguar Summary
The first 'R' model in the latest generation of the XJ range, and the latest in a long line of high-performance, luxurious Jaguar sports saloons, the XJR incorporates bespoke chassis and aerodynamic developments to create the most focused, agile and responsive member of the XJ family.
'This XJR is the flagship XJ and I'm delighted we've got it back into the range. This is a premium luxury supercar that also has an extremely purposeful look to it. This car will surprise, there's no doubt about it.'
Ian Callum, Design Director, Jaguar
Seamless performance is provided by a 5.0-litre supercharged V8 engine that boasts 550PS and 680Nm. Subtle exterior styling cues, which also optimise the flow of air over and around the car, have given the XJR a distinctively assertive appearance. A front splitter, special 'R' bonnet louvres and quad tailpipes also add to the car's §téälthy yet purposeful demeanour.
Combined wîth an eight-speed transmission that extends the performance characteristics of the car, the XJR is capable of accelerating from zero to 60mph in 4.4 seconds (0-100km/h in 4.6 seconds) and on to an electronically limited top speed of 174mph (280km/h).
The unique 20-inch lightweight forged alloy 'Farallon' wheels are shod wîth specially developed Pirelli rubber, giving the XJR a muscular stance and increasing its grip and stability. Allied to the tyre technology are tuned dampers and spring rates which both optimise the handling and stability of the car when driven at speed and increase the feeling of connectivity wîth the road surface, providing a controlled, supple ride which still retains the expected Jaguar XJ ride comfort.
The settings for the active electronic differential and Dynamic Stability Control system have been calibrated in order to allow the enthusiastic driver to make the most of the huge performance potential of the XJR. In addition, the §teering hydraulics and calibration have been engineered to enhance §teering feel, response and feedback under all driving conditions.
The car's dynamic intent is underlined by the technical palette of materials used on the interior. This includes optional semi-aniline leather and veneers in either Carbon Fibre or Piano Black. Providing a further unique touch is a choice of contrasting colour stitching to bring out the design of the front and rear seats.
'The XJR is the sporting pinnacle of the XJ range. This car has been dynamically set-up from the outset to deliver stunning performance, while still retaining the luxury and comfort common to the entire XJ range. The XJR has all the breadth of capability you could wish for in a high-performance luxury saloon car.'
Andrew Dobson, Chief Programme Engineer, Jaguar XJR
5.0-litre supercharged V8
The XJR features Jaguar's acclaimed 5.0-litre supercharged V8 engine in its most potent form, matched to a responsive eight-speed transmission system. This all-new combination provides an exceptional blend of pure performance, driver involvement and exceptional levels of control.
'The challenge wîth developing the powertrain for this car was to place it in character wîth the rest of the vehicle. It needed to have the necessary refinement for use in town while giving all the performance anyone would need everywhere else, without being overwhelming. With the XJR we achieved that balance.'
Ron Lee, Director of Powertrain Engineering, Jaguar

Torque: 501 ft-lbs
The all-aluminium quad-cam engine delivers not only exhilarating performance but also tremendous efficiency thanks to the technologies incorporated into it, including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT).
The high-pressure die-cast lightweight aluminium block is stiffened wîth cast-iron liners and cross-bolted main bearing caps, providing refinement to match its power. The four-valve cylinder heads are constructed from recycled aluminium, between them sitting the Roots-type twin vortex supercharger fed by two intercoolers, which feature their own water-cooling circuit to reduce the temperature of the pressurised air thereby optimising power and efficiency.
The result is a 0-60mph time of 4.4 seconds (0-100km/h in 4.6 seconds) and an electronically-limited top speed of 174mph (280km/h). Eight-speed Transmission
Maximising the benefit of the engine calibration is the eight-speed automatic transmission, which has been engineered based on learnings from the development of the high-performance XFR-S saloon. This transmission system brings out the sporting nature of the XJR while still maintaining the car's composure in town and in low-speed driving environments.
When operating in automatic mode, the transmission can detect the manner in which the car is being driven by monitoring acceleration and braking, cornering forces, throttle and brake pedal activity, road load and kickdown request. On detecting a more enthusiastic driving style, the transmission will automatically make the gearshifts more aggressive and move the shift-up point higher in the rev range. Steering wheel-mounted gearshift paddles also give the driver higher levels of control.
Corner Recognition senses when the car is negotiating a bend, the transmission holding the correct gear for the exit. The transmission will also recognise when the car is performing a series of overtaking manoeuvres requiring rapid changes in throttle position and, rather than change up, remain in a lower gear ready for the next demand for acceleration.
The eight-speed transmission also allows the XJR to be offered as standard wîth Jaguar's Intelligent Stop/Start system. This automatically shuts down the engine when the car comes to a halt and the brake pedal is depressed. When the brake is released, the system will restart the engine in less time than it takes for the driver's foot to move to the accelerator.
A twin solenoid system, it allows for 'change of mind' functionality, bringing the engine back up to speed even during its run-down phase if, for instance, the car is coming to a halt at a junction and the driver sees an opportunity to join the traffic flow. Dynamics
'The XJR offers greater §teering precision, higher levels of control and enhanced high speed stability, wîth the trade-off in refinement being very small. The increase in power and torque give this car truly effortless, seamless performance.'Mike Cross, Chief Engineer, Vehicle Integrity, Jaguar
The dynamic characteristics of the XJR have been informed by the engineering development of the XFR-S, the result being an incredibly agile, responsive and involving luxury super saloon.
Both front and rear suspension systems have been carefully tuned at Jaguar's testing centre at the legendary Nürburgring, the high-speed Rockingham circuit in England, the roads around the Gaydon Research and Development centre and in north Wales.
In order to achieve the maximum benefit from the suspension, the XJR has new lightweight, forged 20-inch 'Farallon' alloy wheels. The tyres, developed in conjunction wîth Pirelli, are 265/35 and 295/30 front/rear and have been selected to deliver optimal cornering grip, traction and stability over a wide range of speed and performance parameters. The difference between the wheel rim and tyre width has the effect of pre-loading the sidewall to improve handling and §teering response without adversely affecting refinement. The §teering system has additionally benefited from the fitment of the valving developed for the F-TYPE.
Working in harmony wîth the suspension, wheels and tyres are electronic programmes controlling the Adaptive Dynamics, active electronic differential and Dynamic Stability Control systems.
Jaguar's Adaptive Dynamics system actively controls vertical body movement, roll and pitch rates through the use of continuously variable dampers. The system monitors driver inputs and the road conditions, adjusting damper rates in response up to 500 times a second to optimise stability and agility. The driver's selection of Dynamic Mode offers enhanced body control through moving the damping rates to the firmer end of the available range.
The Jaguar active electronic differential - which can apply full locking torque almost instantaneously when necessary - has been calibrated in order to exploit the high levels of grip offered by the wide rear tyres, the more precisely controlled suspension and the engine output. Working in parallel wîth the differential, the 'Trac DSC' setting of the Dynamic Stability Control system now offers the enthusiastic driver more opportunity to explore the outer edges of the handling envelope while nevertheless providing a discreet safety net.
Providing equal levels of confidence is Jaguar's High Performance Braking System, which offers an unmatched combination of power, stability and fine modulation. The 380mm front and 376mm rear discs are internally ventilated for assured, repeated stopping power. Design
'The Design Team wanted to create a graphic link to the performance credentials of this car, as well as delivering the optimal balance of aerodynamic down force front and rear. Hence the chrome-rimmed intakes on the front bumper have become an 'R' model 'signature element', acting as a visual reference to the car's twin superchargers, while the front aero splitters are complemented by the rear spoiler. We really dialled up the visual content on the XJR, compared to its predecessors; it's where our customers now expect it to be.'Wayne Burgess, Studio Director, Jaguar Design
Reflecting the changes under the skin, the appearance of the XJR has been subtly modified in order to allow the car to achieve its full potential.
The 'R' spec side sills, unique to the XJR, serve to create a sharp break-off point between the bodywork and the road surface in order to keep the airflow attached to the car's sides for as long as possible.
Rear lift is also reduced through the fitment of a bootlid-mounted lip spoiler to manage the airflow off the top rear surface of the car, while the special 'R' bonnet louvres aid in aerodynamics and engine cooling.
The five-spoke, lightweight Farallon forged alloy wheels provide the XJR wîth a purposeful, broad shouldered stance and come as standard in either Sparkle silver or Technical grey finishes. The assertive appearance of the XJR is further enhanced wîth a Sport pack grille wîth chrome surround and black mesh.
XJR customers can choose from an exterior palette comprising ten colours: Polaris White, Ebony, Últimate Black, Stratus Grey, Lunar Grey, Rhodium Silver, Cashmere, Caviar, Carnelian Red and Black Amethyst.
This colour palette is complemented inside the XJR wîth a unique combination of colourways. Jet leather trim is available wîth a choice of either Ivory, London Tan or Red Zone inserts on the seat facings. The seats themselves are embossed wîth the 'R' logo and can be finished wîth a choice of stitching in either Red or London Tan. Jet suedecloth headlining comes as standard wîth an optional leather headlining in Jet to complement the XJR interior.
The XJR is fitted as standard wîth a 380W, 12-speaker surround-sound system from British audio experts Meridian. Recognised by audiophiles as a leader in audio reproduction and fidelity, the system uses digital signal processing to create a sound field that is second to none. An optional 825W, 18-speaker system features Meridian's proprietary Trifield System which places every occupant at the centre of their own perfectly focused surround-sound arena.Source - Jaguar
The Jaguar XJ series began in 1968 and has continued in various forms and Series into modern times. The first 'Mark' was introduced in 1968 and continued until 1992. During this time there were three series, Series 1, Series 2, and Series 3. In 1986 Jaguar introduced the Mark II which continued until 2002. During this time there were the XJ40, XJ81, X300, X305 and X308. The Mark III was introduced in 2003.
Sir John William hailed the JX series as 'the finest Jaguar ever.' The 'XJ' designation had been used during the vehicles development as its codename. When the vehicle was introduced, the codename persisted. When introduced it was powered by a six-cylinder engine that came in either 2.8- or 4.2-liter displacement. In 1972 a 5.3-liter V12 unit was introduced with a total of 3,235 examples being produced its introductory year. From 1968 through 1973, Jaguar produced 82,126 examples of the XJ Series I.
The Jaguar XJ Series II, commonly known as the Series II, was introduced in 1973. It brought mild aesthetic improvements over the prior years. One of the more visual indications of a Series II from a Series I was the smaller front grille. A 3.4-liter engine became available in 1975. In total, 91,227 examples of the Series II were produced with 14,226 being outfitted with the 12-cylinder engine. 8378 examples were of the two-door XJ Coupes which were produced from 1975 through 1978.
The Series II vehicles had a reputation for pool build quality which was partly due to outsourced components. The XJC versions were plagued with loud wind noise and water leakage.
A limited number of XJC pillar-less hardtop coupes were produced from 1975 through 1978. These are commonly known as the XJC. Their chassis's were constructed on the short-wheelbase version of the XJ. They came equipped with either the six or twelve cylinder engine. Extensive amount of labor was required in order to modify the saloon body to create the XJC. The labor intensive process and high sticker price was part of the reason only 8378 examples were produced.
In 1979 Jaguar unveiled the Series 3 which remained in production until 1992. The famous design studio, Pininfarina, had been tasked with incorporating design enhancements for the long-wheelbase version. The results were stunning.
The Series III were powered by six- and 12-cylinder engines. In six-cylinder form, the owner could select either the 3.4-liter or 4.2-liter unit. The V12 unit had 5.3-liters in displacement size. The larger six-cylinder engine and the 12-cylinder unit both utilized Bosch fuel injection. The smaller six used carburetors and now offered for sale in the US.
In total, there were 132,952 examples of the Series III produced. A small percentage of those, 10,500, were equipped with the 12-cylinder engine. In 1987 Jaguar ceased production of the Series III XJ with the six-cylinder engines. The Series III with the 12-cylinder power-plant continued until 1992.
The Series III brought with it cruise control and a sunroof as optional equipment. The Vanden Plas option was introduced in 1982 and intended for the US market. This designation indicated the top-of-the-line offering for the Jaguar XJ which included the twelve-cylinder engine and many luxury items as standard equipment.
The Project XJ40 had been in development by British Leyland (Jaguar) since the 1970's. Designs by Pininfarina were submitted but ultimately, Jaguar decided to stick with its internal design studio for their newest creation. There were delays with the project which delayed its introduction. These delay's, which included the unforeseen fuel crisis, meant the Jaguar Mark II XJ40 was unveiled to European markets until 1986. Since its design had been started in the 1970's, it brought with it many controversial designs from that era. The square headlights were one of these antiquated features.
Jaguar offered the XJ40 with only six-cylinder units when first introduced. The 12-cylinder unit's were not ready, thus the continuation of the Series III with the V12 until 1992. In 1989 Ford took over Jaguar. Work began on redesigning the engine bay to accommodate the V12. It would take a few more years of development until the V12 was ready.
In 1993 a twelve-cylinder version of the Mark II was ready for sale. By now, the vehicles were known as XJ81. Production would continue until 1994 of these 6.0-liter four-door saloons. Power was sent to the rear wheels through a GM 4L80E four-speed automatic gearbox with overdrive on the fourth gear.
In 1995 the XJ6, code-named X300 Series, was introduced which used styling cues from the popular Series III cars. There were now four individual headlights, reminiscent of the Series III era. The hood was also very similar to the S3. The work of the newly designs and updated X300 Series cars was done by Geoff Lawson, the head designer for Jaguar. Included in this series was the XJ6, Vanden Plas, XJR, and Daimler. Power was from a 4-liter six-cylinder unit or from the 6-liter 12-cylinder unit. The XJR version featured a supercharger on the six-cylinder unit. This was a radical departure from Jaguar's history, as a supercharger had never been used by the Jaguar Company. Turbochargers were almost as rare in the company's long and prestigious history. The XJ220 is one of the few Jaguars, up to this point, to have been outfitted with a turbocharger.
Though the exterior of the car had received attention, the interior received very few updates.
Production of the XJ6 continued into 1997.
The XJ12 and Daimler Double Six as introduced in 1995 and produced until 1996. It was known under the codename X305. Production of the XJ12 was low with only 3400 examples produced. Though they shared many design features as the X300 Series, there was much to distinguish the two series. V12 badges were placed on each side of the vehicles pillar.
The X308 was introduced in 1997 and continued until 2002. Included in this series was the XJ7, JXR, Daimler, and Vanden Plas. The X308 Series brought about an all-new dashboard. The most significant improvement was the use of eight-cylinder engines. They were offered in 3.2-liter, and 4.0-liter displacement sizes. The XJR included a five-speed automatic transmission and a supercharger on the 4.0-liter unit which greatly improvement the vehicles performance. The base 4.0-liter produced 290 horsepower while the supercharger version increased output to 370.
In 2002, Jaguar introduced the XJR 100 which was a limited 500 special edition versions of the XJR. They were all painted in black with matching black leather interior. Alloy sport wheels, red stitching in the interior, and maple trim were used exclusively on the XJR 100.
The Mark III was introduced in 2002 and brought about an all-new aluminum lightweight body. These were codenamed the X350. Included in this series was the XJ6, XJ8, XJR, Vanden Plas, Super V8, and Daimler Super Eight. Visually, the vehicle had changed little. The biggest improvements were under the hood and throughout the other mechanical components. The chassis and body were constructed mostly from aluminum with small amounts of steel.
The Super V8 made its debut in 2004. This was a long-wheelbase version of the XJ and is considered the most luxurious and powerful of the series. As such, it is also the most expensive. Under the hood was a 4.2-liter supercharger V8 that produced 400 horsepower. A limited edition, called the Super V8 Portfolio, was introduced at the 2005 New York Auto Show as a 2006 model. It carried a base price of $115,999. Improvements were more power and luxury enhancements. There were only limited colors offered, either Black Cherry or Winter Gold. Zero-to-sixty took just five seconds.
The Mark III, aka X350, was powered by a 4.2-liter V8 that came in natural aspiration or supercharger. The base engine produced 300 horsepower while the supercharger version raised that figure to 400.
