Seeing as the Jaguar XKR-S is a pretty serious bit of kit with 550PS and 680Nm, when it came to making a new, faster version, Jag engineers focused their efforts on making the car lighter and more aerodynamic. The new Jaguar XKR-S GT is the result of those efforts, and it’s a track-ready road-legal GT car.

The car is built by Jaguar’s ETO division – responsible for special and customized models – and it’s limited to only 30 units, making it the rarest model in 25-year history of Jaguar R performance cars. The XKR-S GT comes with lot of highly advanced motorsport features, among them carbon ceramic brake system, bespoke adaptive dampers are eight-way adjustable with race-derived twin spring system, and new camber, bushings and steering ratio.

Add to that a six-speed automatic transmission with paddle shifters, active electronic differential, as well as a massive GT3-style aero kit consisting of front splitter and winglets, side skirts, rear diffuser and fixed wing – not to mention the 20-inch lightweight alloy wheels with Pirelli Corsa tires – and you end up with a car capable of extraordinary performance.

The GT goes from 0 to 60mph in just 3.9 seconds, but top speed electronically limited to 186 mph (300 km/h). This is one of the most fascinating cars Jaguar has ever made, even though it does not comply at all with Jaguar’s image as a posh and plush British car.
