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 groves 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.
The Dodge Viper ACR uses a slightly tuned variant of its iconic 8.4L V10 engine; producing 645 hp (481 kW) and 600 ft·lb (813 N·m) of torque. It comes equipped with the same Tremec TR6060 six-speed manual transmission as the regular Viper, and power is sent to the rear wheels.
Equipped with the optional Extreme Aero package, the Viper ACR can generate a massive one ton (2000 lb) of downforce at 177 mph (285 km/h), to improve high-speed handling.
The Dodge Viper ACR is one of the best-performing road-legal Vipers due to its massive rear wing that generates extreme amounts of downforce, resulting in excellent handling and tremendous grip; on average, it can corner at 1.32 g and at best, it corners at 1.47 g while traveling at 120 mph (193 km/h).
The Viper ACR also has excellent braking to supplement its extreme handling. It takes only 251 ft (77 m) to brake from 100 mph (161 km/h) to a stop, shorter than most cars in the game. However, due to the extreme amount of downforce it generates, the Viper ACR's top speed is held back to at most 179 mph (289 km/h). Overall, the Viper ACR is suited to tracks with short straights and various turns.
Removing the rear wing and installing engine upgrades can help the Viper ACR reach extreme speeds, but at the expense of grip.
