This is exactly what happens when you play with American muscle. Not only that the Chevrolet Corvette ZR1 beat two Mercedes AMG cars on the same day, but one of the two was actually tuned and modified so its engine produces more than 700 HP. True, Stage 2 kit has been installed on the ‘Vette too so the engine inside developed massive 720 HP. American muscle is far more superior here in relation to German engineering. True, if the cars were stock, the ‘Vette wouldn’t have a chance against the SLS AMG or the C63 AMG Coupe.
