Jaguar XKR-S news - Geneva 2011: Jag reveals hardcore XKR-S - 2011

This is the new Jaguar XKR-S - an uprated version of the quietly legendary XKR. Due to make its debut at the Geneva motor show, the XKR-S still sports the 5.0-litre supercharged V8, but power is up from 510bhp to 542bhp. There's also a boost in torque to 501lb ft (up from 461lb ft).

The hardcore XKR-S gets a new version of Jag's brilliant adaptive dynamics suspension with uprated dampers, active sports exhaust system, and new aero to reduce lift and assist the massive brakes, which measure 380mm at the front and 376mm at the rear - bigger than a Lamborghini Murcielago's. It needs them too because top speed is 186mph, and it should hit 62mph in 4.2 seconds. Look carefully and you’ll see the XJR-S also has new headlamps. Those will go onto the rest of the XK range soon as part of a mild 2012 facelift.

Jaguar also tells us the XKR-S will emit less than 300g/km of CO2, which means it'll be top of its class in the cleanliness stakes.
