2013 Viper

Viper will likely wipe the floor with the Mustang...after all the Viper set a record at that crazy German race/test track. Nurburghg ring? Time was crazy fast 7:24 or maybe even faster than that. Basically it's faster than about 95% of all the super cars tested on that track. About the closest next car I think is a Porche..

Oh and that was the old 2012 Viper. I'll bet money the new one is faster...
