The wait is finally over. Dodge... excuse us, SRT has officially pulled the wraps off the 2013 Viper, and it's everything we were hoping it would be. Let's discuss numbers: 640 horsepower and 600 pound-feet of torque from a front/mid-mounted 8.4-liter V10 and the best power-to-weight ratio of any Viper ever built.
Two models will be available, the standard high-performance SRT and GTS.
In fact, the 2013 SRT Viper's 4.9 pounds per horsepower puts it just behind the Bugatti Veyron and Ferrari F12 and ahead of such performance stalwarts as the Lamborghini Aventador and Chevrolet Corvette ZR1. What's more, this engine has no turbocharger or supercharger, and those 600 lb-ft make this V10 the most torque-rich naturally aspirated production engine in the world.
