Jaguar has announced a special version of the XKR for this weekend’s Goodwood Festival.

The XKR Goodwood Special has ‘been developed as a one-off to explore the harder side of the XKR’s character and explore some performance boundaries’. Unfortunately, all Jaguar says about any engine modifications is that there have been ‘performance enhancements’, but it’s standard output of 500bhp means that it wouldn’t take a great deal of extra power to move the XKR firmly into supercar territory.

As well as the engine changes the XKR gets 21-inch graphite wheels, lowered ride height, slime green paint and satin details for the front grille, headlights, door mirrors, side window surrounds and bonnet louvers. It also gets a ‘louder exhaust’, which given the noise made by the standard XKR that’s currently sitting outside DR HQ should mean a pretty spectacular soundtrack.

The question we all want answering, of course, is whether this special edition is a precursor to a harder, faster, ‘GT3’ version of the XKR?
