I think an equal contest would have been a 640 horsepower ACR-X (top of the line Viper) against the 638 horsepower ZR-1 (top of the line Vette). But equal wouldn't really be "fair" would it? The base Viper was 120 pounds heavier, had 38 less horsepower, no magnetic suspension or traction control and still beat the 'Vette to 60 mph and around the road course. 0-100 was a tie, and considering the 'Vette has carbon ceramic brakes and only stopped 2 tenths of a second faster speaks volumes about the quality and performance of the Viper compared to a car the magazines said would absolutely **** it; a different gear in 5th, and that would have been a very different finish. Congrats to the 'Vette, but if I had to pick I'd still take the Viper
