The two sedans may look like Jaguar S-Types, but according to Fast Lane Daily's spy shot A-Team, they aren't. They are actually XF-R mules disguised as S-Types with large wheels and big, bulging fender flares. They were caught during hot weather testing recently in Death Valley, U.S.A., and FSD reports that their engines did not sound supercharged, a la the XK-R. Rather, they sounded like the naturally aspirated V8 from the Aston Martin Vantage. Though they're not part of the same happy Ford family anymore, Jaguar could now buy engines from Aston Martin and not worry about stepping on the toes of its sister company. However, this is the first we've heard of the engine in the XF-R not being supercharged, so take it with a big grain of salt for now. Follow the jump to check out the latest episode of Fast Lane Daily that features more of these XF-R mules, and check out our own gallery of the XF-R prototype below.
