Jaguar XKR-S looks, sounds beastly

Jaguar has released new footage of the 2012 XKR-S, positively mauling Portugal's Autódromo Internacional do Algarve. As promised, the steroid-fed XK looks to be as fleet-footed as a NASA orbiter, pulling down 60 mph in 4.2 seconds on its way to a 186 mph top speed. It also appears that each and every one of its 542 horses (same as the XJ220) has an insatiable appetite for very expensive tires.

The coolest thing about this big electric blue coupe has to be its evil yowl as heard from inside the garages at the Portimao Circuit. It stands to reason that it should sound good, with a big V8 breathing through what amounts to an open exhaust system, but this big cat has enough aural might to show up even the most hardcore eight-banger from our shores. For the full effect, hit up the video after the jump, and crank the volume up to 11.
