Video: Porsche 911 GT3 RS testing at the Nurburgring

Based on the current 2010 GT3 the rennsport version features a modified 3.8 Liter flat six producing 429 HP. The RS comes with ceramic brakes, adjustable dampers, a huge down force inducing rear wing and numerous other composite pieces to keep the weight down and make this rear engined vehicle handle like it is on rails. Some prefer the ridiculously powerful turbocharged GT2, but to them I say there is just something beautiful about a naturally aspirated vehicle that makes over 100 horsepower per liter.
