2016 Dodge Viper ACR is the fastest street-legal Viper track car yet

May 8, 2015

Dodge has just unveiled the ultimate street-legal, track-focused Dodge Viper yet – the 2016 Viper ACR. It’s powered by the same 8.4L V10 engine with 645 horsepower and 600 lb.-ft. of torque, but a host of other upgrades make the Viper ACR one of the hottest street-legal race cars available.

A new ACR Extreme Aero Package delivers nearly 1 ton of peak downforce at top speed through adjustable dual-element carbon fiber rear wing, rear carbon fiber diffuser, unique SRT hood with removable louvers, detachable extension for the front splitter and additional dive planes. The package gives the Viper ACR the highest aerodynamic downforce of any production car. During on-track testing, development engineers experienced nearly 1 ton of downforce at a top speed of 177 mph.

To keep everything under control, the Viper ACR also gets upgraded Brembo Carbon Ceramic Matrix brakes. The system uses 390-millimeter (15.4-inch) two-piece front rotors and 360-millimeter (14.2-inch) two-piece rear rotors. Front brakes use six-piston Brembo calipers while the rear brakes use four-piston calipers. Of course the Viper ACR also needs upgraded rubber and that comes in the form of Kumho Ecsta V720 high-performance tires designed specifically for the car with unique tread pattern and compounds for front and rear. In testing, the new tires produce laps times that are 1.5 seconds faster than off-road only race tires.

“The Viper has always been more of a street-legal race car than a track-capable streetcar, and the new 2016 Dodge Viper ACR is the fastest street-legal Viper track car ever,” said Tim Kuniskis, President and Chief Executive Officer – Dodge Brand and SRT Brand, FCA – North America. “Our goal is to arm our enthusiasts with the ultimate Viper track car to dominate road courses around the world.”
