This Shelby GT500 you see above is not taking a moment to rest and smoke up! No, it’s warming up its tires to run a quarter mile for the billionth time, as SVT engineers try to fine-tune its Launch Control system. With 662 horsepower, the GT500 is not going to embarrass itself at the drag strip. But on a race track, it might. You see, this car has massive power and fancy electronics, but its rubbish brakes and live rear axles will make it a less formidable car than, say, the Camaro ZL1 as a track toy.
