The Porsche 911 GT2 is a car that needs no introduction. Often nicknamed the widow maker due to its sheer rawness and tendency to go sideways at will, the 911 GT2--as hard as it is to believe--is available in an even more extreme form, as the 2011 Porsche 911 GT2 RS.

This hotter variant is the fastest and most powerful road-going sports car ever built in the history of Porsche, coming with 620 horsepower and a curb weight of just 3,021 pounds with all fluids on board. What will it do? How about 0-62 mph in 3.5 seconds, 0-124 mph in just 9.8 seconds, and 0-187 mph in 28.9 seconds. Top speed is 205 mph. Check out its performance in the clip below.
