Benz SLS AMG vs. Audi R8 V10 vs. Porsche 911 Turbo in Vegas

There isn’t much I can say other then watch the video, it is everything a man can dream of. Motortrend take the three new supercars to the twisting roads of Las Vegas for some head to head testing. I just love the sound of these machines, the R8 does seem to have the best engine, I do love the Gullwings of the SLS AMG, and the new 911 Turbo is just out of this world.
