Fans of the Dodge Viper GTS-R — a special race variant of the Viper that competed in many iconic races including the ultimate test of endurance, the 24 Hours of Le Mans – are now that much closer to driving the real deal with the release of the new Viper GT3-R. Developed by Chrysler’s SRT (Street and Racing Technology) division alongside Riley Technologies, the GT3-R’s 8383 cc engine puts down 680 hp and 640 lb-ft of torque @ 5100 rpm, and is matched with an Xtrac 6-speed paddle shift transmission. The single-seat grand tourer boasts some serious aero add-ons such as carbon fiber, Kevlar and fiberglass parts. As this non-street legal Viper was made with the track in mind, large 380 mm rotors with 6 piston calipers provide stopping power to the front while a 4 pot, 330 mm setup aids in the rear. No racing elements are left out in the GT3-R, as the vehicle comes fully equipped with a FIA homologated roll cage and an on-board fire suppression system. Available for order now, with an expected delivery date of late 2013, the SRT Viper GT3-R comes with a price tag of $459,000 USD.
