We got used to car makers lying about their cars power figures but they normally announce numbers  greater than the real power output. Not Chrysler! The company claimed horsepower for 2009 Dodge Viper ACR is 600 hp but guys at dragtimes put the car on dyno and arrived at a different number, 642 hp!! For no logical reason imaginable they advertise Viper ACR is less powerful than it really is! So no wonder they are going bankrupted!via : Jalopnik
