As Corvette is the title sponsor of Sunday's ABC Sport's broadcast of the Mobil 1 Twelve Hours of Sebring, it only makes sense to educate viewers how closely related the production cars are to the ALMS GT racers. To do so, GM showcases the Corvette ZR1 and tells viewers that when they decided to take 638-horsepower Corvette racing, they had to dial back the power just to be fair to Porsche, Ferrari and BMW. For Corvette's competition on the track and in the showrooms, sometimes the truth hurts.
