SRT Viper GTS-R

The SRT Viper GTS-R (also known as the Dodge Viper SRT GTS-R) is a grand touring race car designed and built by Riley Technologies for use by SRT Motorsports in the GTE category of the American Le Mans Series and its successor series the United SportsCar Championship from 2012 to 2014. Powered by an 8.0L Viper V10, the initial Viper GTS-Rs were built on early 2013 SRT Viper chassis and modified for that aspect; aerodynamics for the car were collaboratively designed by Riley and SRT. The car competed in the American Le Mans Series with success, culminating in a teams championship in 2014; following the 2014 United SportsCar Championship, Chrysler announced they would be discontinuing the factory program for the Vipers. The GTS-R would be replaced in competition by the Dodge Viper GT3-R in 2015. The Viper GTS-R also competed in the 24 Hours of Le Mans in 2013 and 2015 and were originally slated to compete in 2014 before announcing their withdrawal from that years running of the event; bo
