The SRT Viper is one of the rawest performance cars on the market, and in addition to its available adjustable suspension system the coupe offers supernatural handling and unquestionable road presence. The 640 horsepower and 600 lb-ft of torque generated by its 8.4-liter, 10-cylinder engine also guarantees rocket-like acceleration. A six-speed manual is the only transmission available with the SRT Viper, but unlike the previous generation of the car this one comes with traction and stability control.
