The flagship model of the range is once again the XKR sports model, which for 2010 sports a new supercharged 5.0L AJ-V8 Gen III engine generating 510hp and 461lb-ft of torque. This same unit also powers the new XF-R performance saloon, which you can read about by clicking here.
All models are electronically limited to a maximum speed of 155mph, but the 0-60mph sprint for the XKR Coupe is reduced from 4.9 to 4.6 seconds. Despite the extra displacement and performance, fuel-economy is comparable to the previous generation of XKR and carbon-emissions are actually 1% better than the older 4.2L mill. Jaguar claims the car has an average consumption of 23mpg and a CO2 rating of 292g/km – 16 and 17% better, respectively, than the equivalent figures for the BMW M6.
Drive is sent to the rear wheels via an updated six-speed ZF 6HP28 transmission, controlled with either steering wheel-mounted paddles or full automatic mode via the JaguarDrive Selector. The transmission is also paired with an advanced electronic differential on the XKR model.
Visual changes to the car include a new front bumper design, new LED rear lights and a new lower rear bumper spoiler. Other details include chrome-detailed inserts and further chrome detailing to the upper mesh grille, plus a subtle rear spoiler.
Also new are the 19in wheels, which sport a 10-fan-spoke Artura design. These are joined by optional 20in wheels, which come in two different designs.
Inside, there is 10-way seat adjustment for both driver and passenger seats, with heating and memory functions as standard and a unique "R" seat style. Upgrade to the optional R Performance interior, and the car is fitted with 16-way adjustable seats with heating and memory functions, and adjustable side bolsters.
The door casings are even more luxuriously crafted than before, with saddle-stitched lines and a new interlayer to give a softer touch to the top shoulder of the casing. The leather door pulls also introduce twin-needle stitching and a soft-feel interlayer. In each door, the modified seat switch pack now includes single-piece chrome 'highlight' switches.
A touchscreen central monitor provides access and control for the Climate Control and Audio systems, for the Satellite Navigation System, for Bluetooth mobile connectivity and for Jaguar's Portable Audio Interface – which are all standard equipment.
The first cars are expected to hit showrooms in the middle of the year.
