Jaguar XFR-S

Last time we saw the Jaguar XFR-S out testing, it didn't look any different from the already-slick XFR that's on sale right now. But as we get closer to the production car's debut – reportedly scheduled for the 2012 Los Angeles Auto Show – the even-hotter XF's design is coming into focus. And might we say, she's a beaut'.

The XFR's aggressive appearance has been enhanced at the front with larger air intakes that look downright fierce, and lower skirts have been added to the sides. Out back, new bodywork has been added to the quarter panels and a larger lip spoiler adorns the trunk. The whole package looks awesome, and we can't wait to see what this bruiser looks like when all of the swirly paper has been removed.

Under the hood, expect to find Jaguar's delicious 5.0-liter supercharged V8, tuned to the same 550 horsepower as the XKR-S. That's a 40-horsepower increase over the standard XFR, and Jaguar will likely implement some exhaust tuning to make its Top Cat snarl with even greater volume.
