Dodge is throwing a bone to the Viper faithful next year with a new take on the wicked ACR – the ACR-X. Designed to fit perfectly into both the NASA and SCCA Viper Racing League, the car boasts all the safety equipment you’ll need to pass tech, no interior and a serious boost in power. How much is a serious boost? Dodge says the X will hit the dyno for 640 horsepower. That’s a full 40 more than the standard ACR and enough to get you into trouble on track in a hurry. Of course, you still get the same Nuburgring-whooping suspension, but Dodge says it’s cut around 140 lbs from the car’s curb weight. Rock. [Source: Dodge]
