Here is the 2013 SRT Viper GTS – Striking American sports car reviewed and tested at the Willow Springs race track by the VP of design Ralph Gilles who is also SRT CEO and a real car guy. He drove almost four days from Florida to visit Jay Leno in his garage. It must have been a fun drive considering the all aluminium V10 engine that puts out 640 horse power and 600 ft/lbs torque and all the modifications that have been done to the 2013 Viper GTS. Check out the video to hear about it and see this hot sports car on the race track. Watch, Enjoy & Share!
