Porsche claims the 620hp twin-turbo 3.6L 2011 GT2 RS will go full circle of the Nurburgring in 7:18. It achieves this mark by scrapping 154 lbs over the previous GT2 thanks to extensive use of carbon fiber and lighter wheels. The tires (245/35/19 front, 325/30/19 rear) were specifically developed for this 911 GT2 RS and fit under flared wheel arches. Expect to see the cars arrive in the US around October 2010 carrying an MSRP of $245k.
