This is the new top dog of the Jaguar XK family: the XKR-S GT. Built to celebrate 25 years of Jaguar ‘R’ models, the road-legal GT carries a host of track-focused modifications: there’s carbon aerodynamic aids, chassis tweaks, and the promise of a sub-7min 40sec Nurburgring lap time. A regular XKR-S manages 7min 50sec around the 'Ring in comparison.
What’s new on the Jaguar XKR-S GT?
The carbon front winglets, front splitter and rear wing produce a combined 145kg of downforce at the car’s (electronically limited) 186mph top speed. Helping the handling is a 52mm wider front track and adjustable Bilstein dampers. Front and rear spring rates are respectively 68% and 25% stiffer than on the XKR-S. Meanwhile, carbon-ceramic brakes – a first in a road-going Jag – save 21kg in unsprung mass.
Lightweight forged 20-inch alloy wheels wear Pirelli Corsa rubber, measuring 305mm wide on the rear tyres.
The powertrain is unchanged from the regular XKR-S. Under the bonnet is a 5.0-litre supercharged V8, developing 542bhp. It’ll power the rear-drive XFR-S GT to 62mph in 3.9sec – that’s 0.3sec faster than the XKR-S.
Inside, changes are limited to GT badging, a suede steering wheel, and 16-way adjustable leather bucket seats.
Will the Jaguar XFR-S GT be a series production model , like the Porsche 911 GT3 RS?
No – it’s a limited run of 30 models only. Of those, 25 are earmarked for delivery to the USA, and five for Canada. If you want one in right-hand drive, it’ll have to be special order only, as is any other colour than white. As for the price, it’s thought to be around £30,000 pricier than the £97k XKR-S coupe.
What else is Jaguar Land Rover showing off at the 2013 New York motor show?
