The 2013 SRT Viper and the 2014 Corvette Stingray, the two greatest American sports cars ever created. The Corvette is all new for 2014 and sports a 460 hp V8, is capable of running to 60 mph in a scant 3.8-seconds and gets an astonishing 29 mpg on the HWY. The 2013 SRT Viper on the other hand gets an 8.4-liter V10 that makes 640 hp, will also get to 60 mph in 3.8-seconds, but gets only 18 mpg HWY. Oh, and it also cost about 30k more. So, which American super car takes the honors of being the best? Inside Line recently got these two together to find out.
