Dodge proudly introduces the Viper ACR-X, a combination of the record-setting, street-legal Viper ACR and the championship-winning Viper Competition Coupe. The Viper ACR-X utilizes the 600 horsepower ACR as a starting point and with the aid of headers and a low-restriction exhaust system pushes it to a pavement-pounding 640 horsepower. The suspension is upgraded and tuned solely for the track, optimizing its performance on the toughest road courses. Additional aerodynamic upgrades improve downforce, help stability and improve grip in high-speed corners.
This car was not designed for Sunday cruisers. This is a purpose-built race car, created for serious racers only who demand serious speed and performance. The Viper ACR-X, similar to the Viper Competition Coupe, boasts safety features including a factory-designed roll cage, fuel cell, and race seat. Additional racing components have been included to meet the added durability and reliability requirements for competition. With its impressive performance and safety features, no other race car can match the value of the ACR-X – all at a price point very close to that of the street ACR while just a fraction of the cost of the track-only Viper Competition Coupe. Call Viper Race Headquarters at (888) 960-3333 for pricing and custom paint information, which is now available.
