Introduced for the 2013 model year, the Dodge Viper GTS was a variant of the Fifth Generation Viper (VX I). The GTS was the premium offering for the Viper, featuring leather seats, gunmetal trim, and various carbon fiber components like the hood and decklid. Power for the GTS came from an 8.4L V10 engine that had an output of 640hp (645hp from 2015). Drive from this engine was sent to the rear wheels through a 6 speed manual transmission. Production of the Dodge Viper GTS lasted until 2017, when Dodge discontinued the model.
