Chrysler reveals 707 horsepower Dodge Challenger
The Challenger SRT Hellcat will have an eight speed automatic transmission or a six-speed manual. It will be competing against cars like General Motors (GM)' Chevrolet Camaro ZL1 with its 580 horsepower V8 and the 662 horsepower Ford (F) Shelby GT500 which recently went out of production. A Ford spokesman wouldn't comment on its competitors car, but a new Shelby GT500 with, potentially, more power is expected to be revealed some time soon.
