"The new XJR epitomises the three pillars of technology, performance and seductive design which the Jaguar brand
stands for in the twenty-first century, while delivering new levels of dynamic ability in a luxury saloon." said
Adrian Hallmark, Global Brand Director, Jaguar.
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 provide 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 super car
that also has an extremely purposeful look to it. This car will surprise, there's no doubt about it." said Ian
Callum, Design Director, Jaguar.
Seamless performance is provided by a 5.0-litre supercharged V8 engine that boasts 404kW (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 stealthy yet
Combined with an eight-speed transmission that extends the performance characteristics of the car, the XJR is capable
of accelerating from zero to 100km/h in 4.6 seconds, and on to an electronically limited top speed of 280km/h (174mph).
The unique 20-inch lightweight forged alloy 'Farallon' wheels are shod with 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 with the road surface, providing a controlled, supple ride which still retains the expected Jaguar XJ ride
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 steering
hydraulics and calibration have been engineered to enhance steering feel, response and feedback under all driving
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." said 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 with developing the powertrain for this car was to place it in character with 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." said Ron Lee, Director of
Powertrain Engineering, Jaguar.
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
The high-pressure die-cast lightweight aluminium block is stiffened with 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 0-100km/h time of 4.6 seconds, and an electronically-limited top speed of 280km/h (174mph).
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 with 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
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.
"The XJR offers greater steering precision, higher levels of control and enhanced high speed stability, with the
trade-off in refinement being very small. The increase in power and torque give this car truly effortless, seamless
performance." said 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
NÃ¼rburgring, 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 with 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
steering response without adversely affecting refinement. The steering system has additionally benefited from the fitment
of the valving developed for the F-TYPE.
Working in harmony with 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 with 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.
"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." said 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 provide 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 with 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 with a Sport pack grille with chrome surround and black mesh.
XJR customers can choose from an exterior palette comprising ten colours: Polaris White, Ebony, Ultimate Black,
Stratus Grey, Lunar Grey, Rhodium Silver, Cashmere, Caviar, Carnelian Red and Black Amethyst.
This colour palette is complemented inside the XJR with a unique combination of colourways. Jet leather trim is
available with a choice of either Ivory, London Tan or Red Zone inserts on the seat facings. The seats themselves are
embossed with the 'R' logo and can be finished with a choice of stitching in either Red or London Tan. Jet suedecloth
headlining comes as standard with an optional leather headlining in Jet to complement the XJR interior.
The XJR is fitted as standard with an 825W, 18-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
provide a sound field that is second to none. The 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.
