On this episode of Head 2 Head presented by Tire Rack (http://www.tirerack.com), Jonny Lieberman travels just over the Golden Gate Bridge to beautiful Marin County (www.visitmarin.org/motortrend) in two of the most powerful cars ever to roll out of American factories. Five years ago, the idea of a Chevy Camaro ZL1 with 580 horsepower would have seemed like nothing more than the bedroom poster fantasy of a 12-year-old. However, in 2015, 580 ponies seems like something’s wrong. That’s because the Dodge Challenger SRT Hellcat comes strapped with 707! Crazy, we know. However, the Hellcat is heavier than the already pretty large Camaro. Bigger, too. The question then is: which of these two steroidal pony cars should you get? Watch this episode of Head2Head and find out.
