Say Hello to the 2016 Dodge Viper ACR – The Fastest Street-Legal Viper Track Car Ever

Posted by

Today, Dodge announced the arrival of its latest Viper variant, the 2016 Dodge Viper ACR, the fourth ACR variant in SRT’s history.

The 2016 Dodge Viper ACR is built by people who race their own cars, basing their learning on the factory backed Viper GTS-R that competed in the American Le Mans Series and IMSA’s United SportsCar Championship from 2012 to 2014.2016 Dodge Viper ACR

The Viper already delivers 645 horsepower and 600-lb.ft. of torque, but to succeed on the track requires more than just punching a hole in the air. The team focused on aerodynamics, chassis and tires to maximize grip, producing never-seen-before handling capabilities and unprecedented lap times.

“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.”

With the optional Extreme Aero package, the 2016 Dodge Viper ACR is capable of the highest aerodynamic downforce of any production car built. At the car’s top speed of 177 mph, development engineers experienced almost a full ton of downforce.

The Extreme Aero Package features an 1,876-mm wide adjustable dual-element rear wing, rear carbon fiber diffuser, unique SRT hood with removable louvers, detachable extension for the front splitter and four dive planes.

The Extreme Aero package delivers more than three times the downforce of the Viper TA (Time Attack) 2.0 package.

A rear carbon fiber diffuser extends forward of the rear axle, and includes six removable strake extensions, designed to rub against the track surface for increased straight-line stability and optimized downforce.

Hood louvers are removable and reduce air pressure in the front wheel wells, producing even more downforce.

With a car this fast, stopping is as important as going. The 2016 Dodge Viper ACR includes new Brembo® Carbon Ceramic Matrix brakes (15.4-inch front rotors and 14.2-inch rear rotors) for greater braking performance and lower unsprung weight. Front brakes use six-piston Brembo® calipers while the rear brakes use four-piston calipers.

The new Carbon Ceramic Matrix brakes have the largest brake pad area on any Viper ever built.

Sticking the 2016 Dodge Viper ACR to the pavement are Kumho® Ecsta V720 high-performance tires designed specifically for this car, producing lap times 1.5 seconds faster than off-road only race tires.

Sizes are 295/25/19 up front, mounted on wider 11-inch wide wheels, and 355/30/19 at the rear. They offer the largest contact patch of any production car built.

The Viper ACR features an ABS and five-mode Electronic Stability Control system (Full-on, Sport, Track, Rain, Full-off modes) that are specifically tuned for the car to take into account the extra grip offered by the extreme aerodynamic and tire package.

Aluminum bodied, double-adjustable coil-over Bilstein race shocks are designed specifically for the Viper ACR and work in conjunction with ride height adjustment for optimal control of weight transfer and handling performance. Each shock provides independent 10-way rebound and compression adjustability. The suspension package also provides more than 3 inches of ride height adjustment.

Front springs are rated at 600 lbs./in. and rear springs at 1,300 lbs./in., more than double the suspension stiffness of the Viper TA model. With unique race alignment and 1.4 degrees more negative camber than the entry SRT model, the 2016 Dodge Viper ACR is capable of sustaining more than 1.5 g on high-speed turns due to the combined chassis and aerodynamic improvements.

“This car is not a 1-3 lap track special. You can run the car at the track all day, and the performance doesn’t fall off,” added Kuniskis.

Inside, there are also ACR-specific touches including an instrument panel cluster hood, lower instrument panel and door armrest panels wrapped in unique Alcantara suede. The steering wheel is Alcantara wrapped and specific to the ACR. High-grip seats include Alcantara inserts, and a carbon fiber dash plaque denotes its exclusivity.
