Cool cat: Arden releases official details on Jaguar XF AJ 21

Last month, we got a sneak peak at Arden's interpretation of the Jaguar XF, with its aggressive front fascia, LED running lights and rear brake cooling ducts integrated into the side skirts. Now, we've got the official details on the AJ 21 and as is almost always the case, the mods are hardly skin-deep.

The top of the line, supercharged V8 engine has been stroked out from 4.2- to 4.5-liters, with output cresting the 500 hp mark. To make better use of those additional ponies, Arden developed a sports suspension to keeps things planted at speed, while 21-inch "Sportline" wheels are up to the task of combining a bit of style with a dose of functionality. Arden is developing packages for the entire range of XFs, but if we had to choose one, this is it.
