New Dodge Viper Hits the Racetracks This Summer

by Suzanne Ashe

Chrysler combines the Dodge Viper American Club Racer (ACR) and the safety equipment of championship-winning Dodge Viper Competition Coupe, to come up with the Viper ACR-X. The Viper ACR-X is powered by the SRT-developed 8.4-liter V-10 engine, equipped with factory headers and a low-restriction exhaust system, that produces 640 horsepower (40 more than the production model) and 605 lb.-ft. of torque (45 more than the production model).

The new model's suspension also is tuned and upgraded specifically for on-track usage with unique springs, two-way adjustable shocks and adjustable sway bar links. And it has a curb weight that is a 160 pounds lighter (compared with the standard-production Viper) to take on even the most challenging road course.
