|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.|
— Official description 
The 2016 Dodge Viper ACR, abbreviated as Dodge Viper '16 and Viper ACR '16, is a front-engined supercar by Dodge featured in Forza Horizon 3 as part of the Alpinestars Car Pack and in all subsequent Forza titles.
The Viper ACR is an extreme, track-oriented variant of the Phase VX Dodge Viper and the successor to the 2008 Dodge Viper SRT10 ACR. The Viper ACR has also set multiple track lap records, including on Mazda Raceway Laguna Seca and Silverstone Racing Circuit.
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, which improves its aerodynamic performance, the Viper ACR can generate 2000 lb (907 kg) of downforce at its top speed of 177 mph (285 km/h), to improve high-speed handling. It accelerates from 0 - 60 mph (97 km/h) in 3.5 seconds and 0 - 100 mph (161 km/h) in 7.4 seconds.
In a similar fashion to the Aston Martin Vulcan, the Dodge Viper ACR is a track-oriented car with a huge focus on handling and braking. At high speeds, it generates 2000 lb (907 kg) of downforce to turn very sharply, with a tremendous grip far greater than most cars except for the aforementioned Vulcan. The Viper ACR's large rear wing also makes it brake very efficiently; with these traits combined, the Viper ACR comes in handy for tracks that are demanding in terms of curves and their complexity. The Viper ACR does have a low top speed of 179 mph (289 km/h) due to generating a lot of downforce, making it less practical for high-speed situations.
