Sometimes overshadowed by the muscle car war between the Chevy Camaro and Ford Mustang, the Dodge Challenger is another legacy car with history stretching back toward the heyday of American muscle. The all-new 2015 Challenger SRT Hellcat adds an exciting new chapter to that history, hitting the highways as Dodge's most powerful muscle car ever.
Dodge first revealed the 2015 Challenger SRT and SRT Hellcat in May. At the time, it said that the Hellcat would carry its most powerful V8 ever, but it limited its horsepower estimate to "600 plus." The 707 makes for a big dose of "plus," pushing the Hellcat right over the 640-hp Viper V10 and even the Viper GT3-R race car (680 hp). While it's not quite as powerful as special packages like the aforementioned Mustang 1000 and the GT500 Super Snake by Shelby, it easily bests the 662-hp Mustang Shelby GT500 and 580-hp Camaro ZL1 flagships offered directly from Ford and Chevy.
