New York Auto Show Introduction:

The Jaguar XKR-S GT has actually been developed by Jaguar’s ETO division to be the supreme track-focused yet road-going iteration of the XK coupe. Comprehensive aerodynamic and suspension replacements, along with the addition of carbon ceramic brakes, have combined to give the Jaguar XKR-S GT race-car inspired connected feeling and stopping efficiency. Initial production will be limited to just 30 cars for the North American market.

An array of bespoke carbon fiber components, featuring an extended front splitter, dive-planes and elevated rear wing, all add up to take full advantage of the XKR-S GT’s wind resistant downforce. Technical borrowing from the development of the brand-new Jaguar F-TYPE two-seat sports car has actually additionally been used to the XKR-S GT’s suspension and steering systems, improving both immediacy of feedback to motorist input and agility.

Stunning efficiency is supplied by Jaguar’s tested 5.0-litre supercharged V8 engine, including 550PS and 680Nm, driving via a six-speed transmission and active electronic differential. Integrated with the wind resistant and suspension changes, plus modifications to the grip control system’s calibration, the 0-60mph time flashes by in a scant 3.9 seconds. Digitally limited top speed is 186mph.

The Jaguar XKR-S GT is offered in Polaris White with special graphics and Jaguar R-S GT script on its louvered bonnet. The Warm Charcoal interior – with red accents – has 16-way electrically adjustable ‘Performance’ seats finished in soft-grain leather and Suedecloth with the Jaguar and R-S GT scripts incorporated in to the back rests. Jet Suedecloth headlining and a Jet Suedecloth steering wheel, with aluminium paddle shifters, are matched as required. Manuscript on the treadplates highlights the exclusiveness of the Jaguar XKR-S GT.

The advancement of the Jaguar XKR-S GT demanded an uncompromised technique to improve aerodynamic downforce, with complementary suspension changes to maximize high-speed cornering ability. In combination with using a carbon ceramic braking system, the result is the most focused ‘R’ design Jaguar has ever before created which provides increased degrees of performance.

Aerodynamics and framework:

“The Jaguar XKR-S GT has actually been made simply by the regulations of physics. It’s been a physical exercise in performance and the result is an auto that’s raw, concentrated and devastatingly fast.”.

Ian Callum, Director of Design, Jaguar.

The Jaguar XKR-S GT features a carbon-fiber front splitter of race-car wrap-around design; expanding ahead by 60mm, it starts the optimization of air movement around, over and below the car. Aggressive carbon-fiber double dive-planes and wheelarch expansions increase the effectiveness of air movement around the automobile, while below the addition of an aluminium lightweight front valance serves to smooth air flow under the vehicle along with improving engine and brake cooling efficiency.

A back carbon-fiber diffuser makes certain the smooth exit of air from beneath the vehicle, while the elevated rear wing – additionally in carbon-fiber -is in mix with the decklid installed spoiler to maximize rear downforce. At its digitally limited top speed of 186mph, the Jaguar XKR-S GT generates 145kg (320lb) of downforce. Chapeau louvers serve as an additional engine cooling feature while likewise assisting aerodynamic performance by boosting the air movement with the front end of the automobile.

Allied to the extensive wind resistant modifications are comprehensive suspension adjustments.

The front and rear suspension arms, uprights, wheel bearings, bushings and rear subframe are all brand-new and make use of equipment created for the Jaguar F-TYPE. The total set-up works to increase side suspension stiffness for greater preciseness and cooperation.

Integral to the revised suspension system is its new spring and damper module layout. The Jaguar XKR-S GT has a motorsport-derived twin spring system mated to Jaguar’s Adaptive Dynamics damping system – the dampers now being ride-height changeable. Front and back springtime rates are respectively 68 % and 25 % stiffer compared to on the Jaguar XKR-S, while the damper tune is far more track-focused, offering boosted levels of body control and tire grip.

Jaguar’s Adaptive Dynamics have been particularly tuned for the Jaguar XKR-S GT to ensure that the suspension specifications alter to deliver a greater degree of body command with maximum grip and grip when the power mode is selected, offering optimum performance.

The Jaguar XKR-S GT has a front track which is 52mm larger compared to that of the XKR-S while the rear end continues to be the exact same. The steering rack is from the F-TYPE, with a similarly much faster ratio and returned guiding valve. The result is immediacy of turn-in and feedback to steering inputs.

The one-of-a-kind 20-inch built and lightweight alloy wheels – finished in gloss black – are shod with specially established Pirelli Corsa efficiency tires (255/35 and 305/30 front/rear), providing the Jaguar XKR-S GT a much more aggressive grip and substantially enhancing its hold and reliability.

“The Jaguar XKR-S GT is an uncompromising car, yet one that encourages self-confidence and motivates the motorist to press it to its limits, totally exploring its extreme limits. It’s a vehicle that draws you in and is never intimidating, with performance that is both accessible and fulfilling.”.

David Pook, Technical Specialist, Steering and Handling, Jaguar.

Brakes:

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

The inside aerated and cross-drilled lightweight brake discs measure 398mm and 380mm front/rear respectively. Integrated with six-piston monoblock calipers at the front and four piston units at the rear end – the yellow calipers are branded with ‘Jaguar Carbon Ceramic’ manuscript – the Jaguar XKR-S GT delivers race-car levels of fade-free stopping power and brake pedal feel.

Boosted braking feel comes thanks to the electronic Pre-Fill system. Working in combination with the auto’s DSC system, Pre-Fill forces the brakes whenever the driver goes over the throttle pedal, resulting in a very brief and regular level of trip on the brake pedal. This increases braking response, lowers the auto’s quitting proximity and delivers raised levels of confidence throughout high efficiency driving.

The lightweight nature of the carbon ceramic system suggests a decrease in unsprung weight of 21kg – additionally improving the Jaguar XKR-S GT’s handling.

The Jaguar XKR-S GT’s carbon ceramic braking system likewise has a significantly longer life expectancy than a basic system.

“The brake disc and pad products are specifically adapted for Jaguar qualities. Due to the fact that the Jaguar XKR-S GT is a road auto along with one appropriate for clients to tackle the track, we crafted it for race-car stopping efficiency yet without concession to cool or moist weather ability.”.

Edward Nixon, Group Leader, Brakes, Jaguar XKR-S GT.

Performance:

Jaguar’s proven all-aluminum 5.0-litre supercharged quad-cam V8 engine, flaunting 550PS and 680Nm of torque, provides not just exhilarating performance but additionally significant efficiency thanks to the innovations included in to it, including spray-guided direct treatment (SGDI) and double individual changeable cam timing (DIVCT).

The stressful die-cast light-weight aluminum block is stiffened with cast-iron liners and cross-bolted primary bearing limits, giving refinement to match its power. The four-valve cyndrical tube heads are constructed from recycled aluminum, in between them sitting the Roots-type double vortex supercharger fed by two intercoolers, which feature their own water-cooling circuit to minimize the temperature level of the forced air therefore maximizing power and effectiveness.

The Jaguar XKR-S GT includes a totally active performance exhaust system with valves that open under acceleration, both enhancing gas-flow and the auto’s aural character, while improving power output.

The Jaguar XKR-S GT has been established by Jaguar’s ETO branch to be the best track-focused but road-going version of the XK coupe. Extensive wind resistance testing and suspension adjustments, as well as the addition of carbon ceramic brakes, offer the Jaguar XKR-S GT race-car inspired feel and stopping efficiency. The Jaguar XKR-S GT is readily available in Polaris White with one-of-a-kind graphics and Jaguar R-S GT script on its louvered bonnet. The Jaguar XKR-S GT has a motorsport-derived twin springtime system mated to Jaguar’s Adaptive Dynamics damping system – the dampers now being ride-height adjustable. The Jaguar XKR-S GT has a frontal area which is 52mm larger compared to that of the Jaguar XKR-S while the rear end stays the exact same.
