Today, SRT revealed its Viper GT3-R, the latest generation of the Viper GTS-R concept.

The new SRT Viper GT3-R is a collaboration led by Riley Technologies, which has built racing-winning cars from Daytona prototype endurance cars to GT competition cars; their cars have won U.S. GT and endurance championships, including the 24 Hours of Daytona for nine consecutive years.

The SRT Viper GT3-R is the direct descendent of the high performance GTS-R campaigned by SRT Motorsports in the LM GTE Pro Class at the 24 Hours of Le Mans and the American Le Mans Series (ALMS).  The car has a highly-efficient aerodynamic package, Xtrac six-speed sequential transmission with paddle shifters, six-piston front brake calipers with four-piston rears, lightweight wheels, and a multi-disc race clutch for the V-10 engine. SRT CEO Ralph Gilles said, "Like every Viper race car, the GT3-R is a direct descendant of the SRT Viper street car."

The original Viper GTS-R race car made its debut in 1996, and would post three consecutive 1-2 class finishes at the 24 Hours of Le Mans, win overall at the 24 Hours of Daytona, and capture five FIA titles and 16 national GT championships. The Viper Competition Coupe was introduced in 2003 and developed further for its GT3 class debut in 2005.

Orders are now being taken for late 2013 delivery. The price of the new SRT Viper GT3-R is estimated at US$459,000.  For more photos including an under-hood close-up, see our Viper GT3-R page .  (Thanks, Bob Gardetto.)
