2013 Jaguar XFR-S mule spied

Here are the spy shots of the Jaguar XFR-S mule, during testing at Jaguar's facility by the Nurburgring.

The Jaguar XFR-S is an RS version of the XF. It features a slightly wider track than the standard model and the same wheels as the XKR-S cabrio.

Expected, the Jaguar XFR-S will be debuted late in 2012 or early 2013.
