2010 Dodge Viper SRT10 ACR-X
Astronauts, fighter pilots and professional racers know it as the X-dimension. It’s the point at which a vehicle reaches a velocity so intense, reality itself seems like a slow-moving mirage. It’s for these speed junkies that Dodge created the 2010 Dodge Viper ACR-X.
The ultimate combination of the street-legal Viper ACR and the track-only Viper Competition Coupe, the Dodge Viper ACR-X churns out a heart-stopping 640 hp, pushed to the limit with a variety of modifications including headers and a low-restriction exhaust system. Track-tuned suspension and aerodynamics, plus a factory-designed roll cage, fuel cell and race seat mark the ACR-X as a serious racing contender, for serious racers who demand extreme performance.
During the development of the ACR-X, spectacular lap times were posted at Mosport (1:20.6), Sebring (2:08.72) and Moroso (1:17.14).
With all that power at the ready, Viper ACR-X owners put their racing skills to the test in the Dodge Viper Cup, sanctioned by the Viper Racing League. After all, the only thing better than entering the X-dimension is beating another driver to it.
