The following details on Jaguar's XF R mule is courtesy of Brenda Priddy & Co.
"Jaguar has just recently shown pictures of their upcoming XF sedan, and, within days, we caught a “test mule” of its high-performance XF R version!
"This crude-looking mule is comprised of an S Type body, with the front of the new XF tacked on and covered with camouflage. But under the hood lies Jaguar’s 4.2L supercharged V8—hinted by the four exhaust pipes and the group of XK R coupes trailing behind.
"The XF is expected to reach dealers in spring 2008, and the hot XF R model should follow about a year later."
