The appropriately named ACR, or American Club Racer, version of the Viper is little more than a race car with a license plate. The tires are basically slicks with some superficial grooves to make them street legal. Built for the track with a massive wing that contributes around 2,000 pounds of downforce at top speed, the ACR is actually slower than other Viper models, until you take it into a corner, where is sticks like glue and corners like nothing else. With 8.4 liters of V10 under its long nose, you won’t be longing for power either. Unleash this venomous snake for one of the rides of your life.
