When today’s Dodge Viper launched for the 2003 model year, it boasted 500 horsepower and 500 lb.-ft. of torque from a 500 cubic-inch engine. But with the recent introductions of vehicles that make similar amounts of motive force for less money, Dodge needs to inject more venom into the Viper to keep its sports car at the top of the heap. Note how small the hood vents are on this 2006 Viper Coupe.
