Pick a Ride
The 5th-generation Dodge Viper ACR (2016) is the most extreme street-legal Viper ever produced. Power comes from an 8.4-litre naturally aspirated V10 producing 645 hp and 600 lb·ft of torque, driving the rear wheels exclusively through a 6-speed manual gearbox — no automatic, no electronic stability control. Curb weight is 1,560 kg.
The ACR’s Extreme Aero Package generates 770 kg of downforce at top speed — more than any other production car at launch. Its huge rear wing, dive planes, and adjustable dampers helped it set production-car lap records at 13 different North American tracks during 2016, including Laguna Seca and Road America. Production ended that same year, making the ACR a fitting send-off for the long-running Viper nameplate.
