Jaguar’s mid-sized luxury sedan contender, the S-type will now be called the Jaguar XF. To be built at Jaguar’s Jaguar’s Advanced Manufacturing Centre at Castle Bromwich in Birmingham, UK and set to be released in late 2007, it unifies Jaguar’s model naming conventions – it already has new models called the XJ, XK and the XKR.

No shots of the actual model are available yet, so let’s have a look at the Jaguar R-D6 Concept showcased in the year 2003, featuring an S-type-like grille, and Jaguar’s lightweight structure stretegy. The R-D6 weighs only 1,500kg, light for it’s size, makig it easy for it’s 2.7 litre twin turbodiesel’s 230hp and 500Nm of torque to push it along.
