If you believe that the XKR-S is already extreme you’d better think again as Jaguar unveiled today at the 2013 New York Auto Show the XKR-S GT. Developed by Jaguar’s ETO division, the XKR-S GT is described as the ultimate track-focused but road-going iteration of the XK Coupe. The first visual impact with the XKR-S GT shows a range of bespoke carbon fibre components, including an extended front splitter, dive-planes and a new rear wing.
Moreover, the car also features wheelarch extensions, a rear carbon fiber diffuser (which ensures the smooth exit of air from underneath the car) and new bonnet louvres that server as a futher engine cooling aid. Still, the bonnet louvres improve the airflow through the front of the car. Allied to the extensive aerodynamic revisions are detailed suspension changes. As a result, the front and rear suspension arms, uprights, wheel bearings, bushings and rear subframe are all new and draw on hardware developed for the F-TYPE.
Front and rear spring rates are respectively 68% and 25% stiffer than on the XKR-S. The XKR-S GT has a front track which is 52mm wider than that of the XKR-S while the rear remains the same.
The design of the car is completed by the unique 20-inch forged and lightweight alloy wheels finished in gloss black. The wheels are wrapped in high-performance Pirelli Corsa tyres (255/35 and 305/30 front/rear). The wheels hide the internally ventilated and cross-drilled lightweight brake discs measure 398mm and 380mm front/rear respectively.
The XKR-S GT is the first production Jaguar to be fitted with a carbon ceramic braking system. The lightweight nature of the carbon ceramic system means a reduction in unsprung weight of 21kg - so further enhancing the XKR-S GT's handling. Under the hood, there is the same 5.0-liter supercharged quad-cam V8 engine found on the XKR-S and capable to deliver 550 PS and 680 Nm of torque.
As expected, the XKR-S GT uses a six-speed automatic transmission. 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. According to the official press release, the XKR-S GT is capable to sprint from 0 to 60 mph (96 km/h) in 3.9 seconds and has a top speed of 186 mph or 300 km/h. If you really want this car you’d better hurry up as Jaguar will produce only 30 units of the XKR-S GT, making it the rarest 'R' model in the 25-year history of Jaguar's R performance cars.
