Jaguar XKR-S GT 2013



"The XKR-S GT is the Most Extreme iteration of the Jaguar R Brand's performance focus. Utilising race car derived technology, all-aluminum structure and an uncompromised approach to aerodynamic efficiency, the result is a car you can on the track as it is exhilarating on the road. " Adrian Hallmark, Global Brand Director, Jaguar


Summary

A ranks of bespoke carbon fiber components, Including an extended front splitter, dive-planes and elevated rear wing, all work to maximize the XKR-S GT's aerodynamic downforce. Technical learning from the development of the new Jaguar F-Type two-seater sports car HAS aussi beens Applied to the XKR-S GT's suspension and steering systems, Optimising Both immediacy of response to driver input and agility.


Stunning performance is provided by Jaguar's proven 5.0-liter supercharged V8 engine, boasting 550PS and 680Nm, driving through a six-speed transmission and active electronic differential. Combined with the aerodynamic and suspension exchange, more revisions to the traction control system's calibration, the result in straight-line terms is a 0-60mph time of 3.9 seconds. Electronically limited top speed is 186mph.

The XKR-S GT is only available in Polaris White with graphics and RS GT Jaguar script on icts louvred bonnet. The Warm Charcoal interior - with red accents - features 16-way Electrically adjustable 'Performance' seats finished in soft-grain leather and Suedecloth with the Jaguar and RS GT scripts integrated into the backrests. Suedecloth Jet headlining and a Jet Suedecloth steering wheel, with aluminum paddle shifters, are fitted as standard. Treadplates script to the console and highlight the exclusiveness of the XKR-S GT.



Seamless performance is provided by a 5.0-liter supercharged V8 engine That Boasts 550PS and 680Nm. Subtle exterior styling cues, aussi All which optimizes the flow of air over and around the car, Have Given the XJR has distinctively assertive appearance. A splitter, special 'R' bonnet louvres and quad tailpipes aussi add to the car's stealthy yet purposeful demeanor front.

"The development of the XKR-S GT Demanded an uncompromised approach to Enhance aerodynamic downforce, suspension with complementary currency to maximize high-speed cornering ability. In combination with the use of a carbon ceramic braking system, the result is The Most Focused 'R 'HAS model Jaguar ever built Delivers All which heightened levels of performance and driver reward. Pete Simkin, Director, Specialist Products ETO, Jaguar

Aerodynamics and frame

"The XKR-S GT has-been designed purely by the laws of physics. It has-been Developed in the wind tunnel and on the racetrack with the sole aim of Creating as much high-speed stability and downforce as possible. Nothing has-been styled for the sake of it. It's been an exercise in efficiency and the result is a car that's raw, Focused and devastatingly quick. " Ian Callum, Director of Design, Jaguar


A carbon-fiber rear disseminate Ensures the smooth exit of air from underneath the car, while the elevated rear wing - also in carbon-fiber - works in combination with the decklid spoiler mounted to maximize rear downforce. At icts Electronically limited top speed of 186mph, the XKR-S GT Produces 145kg (320LB) of downforce.Bonnet louvers serve as a further Top aid engine cooling while helping aussi Improving aerodynamic performance by the airflow through the front end of the car.

The front and rear suspension arms, uprights, wheel bearings, bushings and rear subframe are all new and we draw Developed hardware for the F-type. The overall set-up works to Increase lateral suspension stiffness for Greater precision and responsiveness.


Integral to the revised suspension system is icts new spring and damper unit design. The XKR-S GT HAS motorsport-derived twin spring system mated to Jaguar's Adaptive Dynamics system damping - the dampers now Being ride-height adjustable. Front and rear spring rates are respectively 68% and 25% stiffer than on the XKR-S, while the damper tune is much more track-focused, supplier providing Increased levels of body control and grip.

Jaguar's Adaptive Dynamics Have Been SPECIFICALLY tuned for the XKR-S GT So THAT the suspension parameters change to deliver a higher level of body control with maximum traction and grip When the dynamic fashion is Deployed, Focused Offering optimum performance for track driving.


The XKR-S GT HAS forehead track All which is 52mm WIDER Than That of the XKR-S while the rear remains the same. The steering rack is from the F-TYPE, with a correspondingly faster ratio and retuned steering valve. The result is immediacy of turn-in and response to steering inputs.

The single 20-inch forged and lightweight alloy wheels - finished in gloss black - Developed specially are shod with Pirelli Corsa performance tires (255/35 and 305/30 front / rear), giving the XKR-S GT has more muscular stance and Greatly Increasing icts grip and stability.


"The XKR-S GT is an uncompromised because purpose One That inspired confidence and encouraged the driver to push it to its limits, fully exploring icts handling abilities. It's a car That draws you in and is never intimidating, with performance That Is Both and rewarding available. " David Pook, Technical Specialist, Steering and Handling, Jaguar

Brakes

The XKR-S is the first generation GT Jaguar to be fitted with a carbon ceramic braking system.

The Internally ventilated and cross-drilled lightweight brake discs measure 398mm and 380mm front / rear respectively. Combined with six-piston monoblock calipers at the forehead and four piston units at the rear - the yellow calipers Being branded with 'Jaguar Carbon Ceramic' script - the XKR-S Delivers GT race car levels of fade-free stopping power and brake pedal feel.


Enhanced braking feel comes courtesy of the electronic Pre-Fill system. Working in Conjunction with the car's DSC system, Pre-Fill PRESSURIZED the brakes every time the driver comes off the throttle pedal, resulting and in a very short level and consist of travel on the brake pedal. This maximized braking response, Reduces the car's stopping distance and Delivers Increased levels of confidence falling on high performance driving.

The Nature of the lightweight carbon ceramic system has means clustering reduction in unsprung weight of 21kg - so further Top Enhancing the XKR-S GT's handling.


The XKR-S GT's carbon ceramic braking system Significantly Also has a longer life span than a standard system.

"The brake disc and pad materials are specially tailored for Jaguar characteristics. Because the XKR-S is a GT road car as well as one suitable for customers to take on the track, we engineered it for race car braking performance goal with no compromise to cold or wet weather ability. " Edward Nixon, Group Leader, Brakes, Jaguar XKR-S GT

Performance

Jaguar's proven all-aluminum 5.0-liter supercharged quad-cam V8 engine, boasting 550PS and 680Nm of torque, Delivers not only exhilarating performance goal aussi tremendous efficiency thanks to the technologies incorporated into it, Including Direct injection spray-guided (SGDI) and dual independent variable cam timing (DIVCT).


The die-cast high-pressure lightweight aluminum block is stiffened with cast-iron liners and cross-bolted main bearing caps, supplier providing refinement to match icts power. The four-valve cylinder heads are constructed from recycled aluminum betweens em sitting the Roots-type twin-vortex supercharger fed by two intercoolers, Their Own All which feature water-cooling system to Reduce the temperature of the air Pressurised Thereby Optimising power and efficiency.


The XKR-S GT features a fully active performance exhaust system with valves That open under load, both, Enhancing gas flow and the car's aural character, while Optimising power output.


In straight-line terms, the significant powertrain's output, combined with the aerodynamic, suspension and traction control software revisions, mean the XKR-S GT can sprint from 0 to 60mph in 3.9 seconds and onto an Electronically limited top speed of 186mph.
