i like corvette stingrays and dodge vipers both. but probly the first would be more fuel efficient just because the latter is more bulky idk I'm just guessing
The chassis on the viper is stiffer and the ride quality is brutal. Viper owners actually like that as it is close as you can get to a street legal race car you can buy with a warranty. The corvette is more efficient and does get better MPG but it is not because the viper is bulky.
