Jaguar has just recently shown pictures of their upcoming XF saloon, and within days we caught a 'test mule' for their high-performance XF-R version! This crude-looking mule comprises an S-Type body, with the front of the new XF tacked on and covered with camouflage. But under the hood lies Jaguar’s 4.2-litre supercharged V8 – hinted by the four exhaust pipes and the group of XK-R coupes trailing behind.

The XF is expected to reach the dealers in the spring of 2008, and the hot XF-R model should follow about a year later.
