Jaguar is commemorating 25 years of its R performance brand with the most focused road-going version of its XK ever.
The XKR-S GT, which joins the new XJR at the New York motor show, is a track-ready version of the XKR-S that remains road legal.
Power comes from a 542bhp supercharged 5.0-litre V8 that sends power to the rear wheels through a six-speed auto’ gearbox. The GT is good for a 0-100kph time of 3.9sec, some 0.3sec quicker than the standard XKR. Although Jaguar says the car is theoretically capable of 320kph, it is limited to 300kph.
The GT features a bespoke aerodynamic package that includes a carbonfibre front splitter, dive planes, extended wheel arch spats, a rear diffuser and a large fixed rear wing. Maximum downforce of 145kg is said to be achieved.
Carbon ceramic brake discs are fitted, a first for Jaguar. New front and rear suspension systems also feature, including a wider front track, increased camber, revised bushings and a new steering system with a faster ratio. Bespoke, height-adjustable dampers are another addition that features a race-derived twin spring system.
Completing the transformation are special lightweight 20in alloys shod in 255/35 Pirelli Corsa rubber at the front and 305/30 tyres at the rear.
Just 30 examples will be made – 25 for the US and five for Canada. However, Jaguar says it will consider right-hand drive models for the UK and other markets if demand is sufficient.
