Based on the XKR-S, the GT version gets the same 5.0-liter supercharged V8 engine developing 542hp (550PS), mated to the same six-speed automatic gearbox. What makes the XKR-S GT stand out from its sibling, though, is the racing-style bodykit, dominated by a huge carbon fiber rear wing. Jaguar states the aero aids help the XKR-S GT achieve maximum downforce of 145kg (320 lbs).
Extra vents in the hood and a carbon fiber rear diffuser complete the XKR-S GT’s performance-oriented bodykit. While the car’s electronically limited top speed is the same as the regular XKR-S at 186mph (280km/h), the 0-60 mph (0-96 km/h) drops from 4.2 to 3.9 seconds, thanks to the improved aerodynamics.
Compared to the XKR-S, the GT version has racing-inspired twin-rate springs and upgraded height-adjustable dampers, 68 percent and 25 percent stiffer front and rear respectively. It also has a 52mm-wider front track and the faster steering rack from the F-Type.
The GT is also the first Jaguar to feature carbon ceramic brakes, with 398 mm (15.6 in) and 380mm (14.9 in) front/rear discs and yellow calipers. Fitting this system saved 21 kg (46 lbs) of the car’s mass, according to the release.
Finally, the XKR-S GT has unique 20-inch alloy wheels with Pirelli Corsa tyres specially developed for the car. Initial production will be limited to just 30 units, making it the rarest ‘R’ model in the 25-year history of Jaguar’s R performance cars.
