Check out this all-American showdown.
You can’t talk about American supercars without mentioning these homebred beasts. The SRT Viper TA is a track-focused snake with a beefed up chassis and 8.4-liter V10 delivering 640 hp and 600 lb-ft of torque. This particular puppy has been modified with an engine tune, and new intakes and exhaust system, presumably giving it a nice boost in performance. The C6 Z06 has also been upgraded with Heads/Cam installation, and the result of these collective mods is a pretty fair matchup.
American supercars don't come much nastier than these. Check them out fighting on the street.
