2013 Viper

Chrysler is still behind in the horsepower wars. :banghead:

The 2013 Shelby Mustang has 650 HP and 200 MPH. :prayer:
At the end of the day though, it's still another Mustang. Plus, the Viper engine is a normally aspirated not super-charged like the GT500 Mustang. Imagine what Hennessy will do with this engine! Plus, at 600 lb ft of torque, the stock engine has highest torque of ANY normally aspirated engine! That is one bad@ss car!
