C&D claims that the Corsa R-compound car was lapping the 1.88 mile track just as quickly as the current BMW M3 they brought along. But how could a 315 hp car keep up on a track with a 414 hp car? Weight? Maybe, because the Mustang weighs about 200 pounds less than the M3. Don't say torque, because the Mustang only beats the M3 by 25 lb-ft there. Tires? Well maybe, but the Michelin Pilot Sport 2s on the Bimmer are pretty sticky in their own right. Despite all that, 414 horses should have cleaned up.

Well, what if the 2011 Mustang Mule with the fancy tires had a 5.0-liter, 32-valve DOHC Coyote engine kicking out 400+ hp and 400+ torques. The world's worst kept secret engine could also explain the similar lap times.
