The M3 GTS weighs in at about 3200 pounds* in the same condition, giving a power to weight ratio of 7.2 pounds per horsepower.
As for torque, it pretty much doesn't matter out there on a race track, where you're always staying as close to the power peak as you can.
*BMW says the GTS comes in at 3285 pounds under Euro rules, which assume a 165 pound driver but I think only a few gallons of gas. Subtract the driver and add gas for comparable U.S. SAE curb weight. Thus around 3200 pounds net under SAE rules.
Impressive, and thanks for the detail. Around May 2012 there were rumors on the GT500 getting Nordschleife lap times, but haven't seen anything since. Very curious to see how it stacks up against the Camaro ZL1 now, given they are head to head competitors.
After further thought...I know many don't like the "retro" direction a lot of american cars are taking, but the idea of have a OEM 662hp Matte Black Cobra stang that can achieve 200+ mph is the definition of an american muscle car. It's just raw in your face straight line power at a relatively attainable price point. That is something I can't think of any other car delivering at that level.
