In the world of high-performance sports cars you can never have enough. There is no such thing as enough power, enough handling and enough speed. The German backwards engineered sports car maker Porsche knows this all too well. That is exactly why they are always refining their vehicles, like this GT3 RS seen lapping the ‘Ring.

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.
