The more extreme performance sedan has been touted for the past year or so, and has even been spied undergoing development work at the Nürburgring. Following a formula similar to what Jaguar employed to transform the XKR into the XKR-S (pictured above at center), the 5.0-liter supercharged V8 in the XFR-S would have its output – and its price – raised to compete with ze Germans. That means 550 horses and about $90,000.
