2010 Porsche 911 GT3

The 2010 Porsche 911 GT3 is unquestionably bad-ass. Its naturally aspirated 3.8-liter flat-six provides 435 hp from behind the driver's seat, and its track-tuned chassis can dance with the world's most nimble supercars. The free-wheeling product of Stuttgart has been undergoing testing at the famed Nurburgring in Germany (along with every other sports coupe worth its salt) and it's been timed at an unofficial 7:40. Porsche driving ace Walter Rohrl was behind the wheel for the sprightly lap.

While 7:40 isn't enough time to best the 7:26 from the 638 hp Corvette ZR1, it's a very impressive time nonetheless (BTW - During testing Rohrl posted a 7:45 in a borrowed Ferrari F430 Scuderia). Nissan probably isn't impressed, though, since it recently clocked the GT-R at 7:27. Well, Porsche is still calling balderdash on that claim, telling Motor Trend that the twin-turbo Nissan is only good for a time of 7:56 in stock US form. Just under eight minutes is an amazing time, but almost 30 seconds slower than reports from Nissan.
