Reintroduced in 2008, the Viper ACR (American Club Racing) featured the same 600 hp and 560 lb-ft engine as the SRT-10, but it was 40 pounds lighter and produced ten times the downforce of the standard Viper at 150 mph thanks to its aerodynamic upgrades.
Other upgrades included two-piece brake rotors, adjustable suspension and Michelin Pilot Sport Cup tires. The ACR completed the fourth fastest production car lap in 7:12.13 minutes, being quicker than the Lexus LFA with Nurburgring Package and the Chevrolet Corvette C6 ZR1.
