After announcing production of the Viper would cease in the summer of 2010, Chrysler did an about face and unveiled the 2013 SRT Viper at the 2012 New York Auto Show. Powered by an all-aluminum 8.4 L V10 producing 640 hp and 600 lb-ft of torque, the 5th generation Viper was designed to be more accessible and forgiving to drivers. The Tremec TR6060 manual 6-speed was once again the only gearbox offered. The hood, roof and decklid are carbon-fiber, the door panels are aluminum and the Sabelt racing seats feature Kevlar/fiberglass shells. The new Viper has the most torque of any naturally aspirated, street legal production car. Once the car becomes available to the public and is officially tested, we will update the performance data.
