The only way you can say the 2013 Viper is a disappointment is if you were expecting it to come with an actual living, breathing, hissing viper as its hood ornament. The power numbers of this thing put it among the best in the world: 640 horsepower; 600 pound-feet of torque; and the best power-to-weight ratio of any Viper ever. You get stability and traction control along with Pirelli P Zero Z-rated tires designed specifically for the Viper. Inside, you’ll sit on silky seats from Sabelt and let a seven-inch LCD screen be your guide to what you wanna hear on the Harmon Kardon sound system. If your budget is a little tight these days, maybe you can swing a virtual Viper when Forza 4 drops the DLC pack soon.
