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 all-aluminum 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 aluminum 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 aluminum, 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 pressurized air thereby optimizing power and efficiency.
The result is a 0-100km/h 4.6 seconds and an electronically-limited top speed of 280km/h.
Maximizing the benefit of the engine calibration is the eight-speed automatic transmission. 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 kick down 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 recognize when the car is performing a series of overtaking maneuvers 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 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.
“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.”
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 center at the legendary Nürburgring, the high-speed Rockingham circuit in England, the roads around the Gaydon Research and Development center 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 tires, 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 tire 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 tires are electronic programs 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 optimize 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 tires, 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 dialed 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 trunk lid-mounted lip spoiler to manage the airflow off the top rear surface of the car, while the special ‘R’ hood 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 colors: Polaris White, Ebony, Ultimate Black, Stratus Grey, Lunar Grey, Rhodium Silver, Cashmere, Caviar, Carnelian Red and Black Amethyst.This color palette is complemented inside the XJR with a unique combination of color ways. 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 suede cloth headlining comes as standard with an optional leather headlining in Jet to complement the XJR interior. The XJR is fitted as standard with a 380W, 12-speaker surround-sound system from British audio experts Meridian. Recognized 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 center of their own perfectly focused surround-sound arena.
