The new Jaguar XKR was unveiled at the 2009 Detroit Auto Show this weekend

The new generation of Jaguar XK and XKR coupe and convertibles, with all-new V8 engines, deliver more power and performance with greater efficiency for 2010 Model Year. With interior enhancements, advanced lightweight aluminium body structure and a wider range of models, plus the new luxurious ‘Portfolio’ model, the new Jaguar XK and XKR build on 60 years of legendary performance to deliver the best of everything Jaguar.

The all-new AJ-V8 Gen III direct-injection engines are the most advanced and efficient petrol engines Jaguar has ever produced.

The Jaguar XKR features a 5.0-litre supercharged AJ-V8 Gen III delivering 510PS (510bhp, SAE), 625Nm of torque propelling it to 60mph in just 4.6 seconds.

The Jaguar XK features a 5.0-litre naturally aspirated AJ-V8 Gen III delivering 385PS (385bhp SAE), 515Nm of torque propelling it to 60mph in just 5.2 seconds.

Both models have improved fuel economy and CO2 emissions which meet the forthcoming EU5 emissions legislation.

Exterior changes for the Jaguar XK and XKR include a distinctive and purposeful new front end design, new LED rear lights and a new lower rear body valance. Inside the cabin, both the Jaguar XK and XKR feature the exciting, user-friendly JaguarDrive Selector that was first seen on the Jaguar XF to further enhance the Jaguar XK’s luxury sporting character.

There are now three models in the range: Jaguar XK, XK Portfolio and Jaguar XKR. The Jaguar XK is priced from £59,900 for the coupe and £65,900 for the convertible and the Jaguar XKR starts from £72,400 for the coupe and £78,400 for the convertible. These models are available from late March 2009.
