The all aluminum V10 engine has a slight increase in capacity to 505 cu. in. This pushes the power output to 500 horsepower and 525 lb.ft. of torque. DaimlerChrysler states that the engine architecture remains much the same as the previous Viper. Minor improvements include a refined cyinder head, valvetrain and a larger cooling system.
DamlierChysler have taken 100 pounds off the car by updating several components: the now-standard run-flat tires eliminated the need for the spare tire, a new magnesium dash replaces the old one and the fenders are now resin injection molded (RIM).
