2015 Dodge Challenger SRT Hellcat: 707 Horsepower? Hell Yeah!

Carlos Lago drives the most powerful production muscle car on the market: The Dodge Challenger SRT Hellcat. While it isn't the most powerful production V-8 in the world (which loses to the $1 million McLaren P1 by 20 hp before electric motors), the Hellcat's 707 hp rating seems too incredible to believe -- especially when you consider the cost.
