The XKR-S GT has been developed by Jaguar's ETO division to be the ultimate track-focused but road-going iteration of the XK coupe. Extensive aerodynamic and suspension changes, as well as the addition of carbon ceramic brakes, have combined to give the XKR-S GT race car inspired connected feel and braking performance. Initial production will be limited to just 30 cars for the North American market.

A range of bespoke carbon fibre components, including an extended front splitter, dive-planes and elevated rear wing, all work to maximise the XKR-S GT's aerodynamic downforce.

Technical learning from the development of the new Jaguar F-TYPE two-seater sports car has also been applied to the XKR-S GT's suspension and steering systems, optimising both immediacy of response to driver input and agility.

"The XKR-S GT is the most extreme iteration of the Jaguar R Brand's performance focus. Utilising race-car derived technology, all-aluminium construction and an uncompromised approach to aerodynamic efficiency, the result is a car as capable on the track as it is exhilarating on the road," said Adrian Hallmark, Global Brand Director, Jaguar.

The unique 20-inch forged and lightweight alloy wheels - finished in gloss black - are shod with specially developed Pirelli Corsa performance tyres (255/35 and 305/30 front/rear), giving the XKR-S GT a more muscular stance and greatly increasing its grip and stability.

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 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.

Stunning performance is provided by Jaguar's proven 5.0-litre supercharged V8 engine, boasting 542bhp and 680Nm, driving through a six-speed transmission and active electronic differential. Combined with the aerodynamic and suspension changes, plus revisions to the traction control system's calibration, the result in straight-line terms is a century sprint time of 3.9 seconds. Electronically limited top speed is 300km/h.

The XKR-S GT is available in Polaris White with unique graphics and Jaguar R-S GT script on its louvred bonnet. The warm charcoal interior - with red accents - features 16-way electrically adjustable 'Performance' seats finished in soft-grain Warm Charcoal leather and Suedecloth with the Jaguar and R-S GT scripts integrated into the backrests.
