Spied: 2013 SRT Viper GTS High Altitude Testing in Colorado > The Fast Lane Car

( http://www.TFLcar.com ) The monster V-10 2013 SRT Viper GTS is not for sale or even on the road yet but we caught one in the wild at the top of Loveland Pass, Colorado. We assumed that it was high altitude testing but when the engineers saw us with the camera they didn't stick around to explain what they were doing.
