MotorTrend has taken three of today’s most desirable supercars (Mercedes SLS AMG, Audi R8 V10, Porsche 911 Turbo) for a drive outside Las Vegas.
We are pretty surprised to see that the California Highway Patrol has accepted to close a portion of the road just to allow MotorTrend to film the Mercedes SLS AMG vs Audi R8 V10 vs Porsche 911 Turbo footage, so if you want to hear three German engines play some ‘music’ across the desert here is your chance.  
Watch the video with the Mercedes SLS AMG vs the Audi R8 V10 vs the Porsche 911 Turbo after the jump.
