Jaguar unveiled the XKR-S Convertible at a Rodeo Drive event on Tuesday night. Jaguar design chief Ian Callum called it, "the fastest convertible in the world," with a top speed of 190 mph and a zero-to-60 time of four seconds.

With a 550hp V-8 under the hood, this car lapped the famed Nürburgring in under eight minutes. And with a sticker price of $138,875, give or take a few quid, the XKR-S Convertible will be a rare bird on these shores; for now, only 25 are slated for export to U.S. dealers.
