One of the most iconic high-performance vehicles of the last decade is returning to uphold its legacy as the ultimate street-legal race car. Hand-built in Detroit and certified for public roads, it’s the all-new 2016 Dodge Viper ACR.
The 2016 Dodge Viper ACR is engineered to wring every last hundredth of a second out of road course lap times and combines the latest in aerodynamic, braking and tire technology to carry on the ACR’s lap-time busting reputation that has made it a legend on race tracks around the world.
“The Viper has always been more of a street-legal race car than a track-capable street car, 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.”
The SRT engineering team that developed the 2016 Dodge Viper ACR is stocked with members who race their own cars and used lessons learned from the factory-based racing Viper GTS-R that competed in the American Le Mans Series and IMSA United SportsCar Championship from 2012-2014. For the new Viper ACR, the team focused its efforts on three areas: aerodynamics, chassis and tires to maximize grip, producing never-seen-before handling capabilities and unprecedented lap times.
The 2016 Dodge Viper ACR is designed to provide the ultimate in aerodynamic performance, and when equipped with the new Extreme Aero Package, the ACR produces the highest aerodynamic downforce of any production car. During on-track testing, SRT engineers have experienced nearly 1 ton (approximately 1,800 lbs.) of downforce at top speed of 177 mph.
The Extreme Aero Package includes a huge (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 rear wing, specifically designed for air flow around the Viper’s body, stands taller, sits further rearward and features unique end-plates and gurney lip to produce maximum downforce while minimizing straight line drag. For comparison, the Extreme Aero package delivers more than three times the downforce produced by the Viper TA (Time Attack) 2.0 package.
The 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. Removable hood louvers over the front tires reduce air pressure in the front wheel wells, and the detachable front splitter extension and dive planes work with the rear aero treatment to provide outstanding grip and balanced performance on the track.
Track duty can punish the brakes, so the 2016 Dodge Viper ACR features new Brembo® Carbon Ceramic Matrix brakes that provide optimum braking performance with unprecedented brake fade resistance. Designed to provide greater handling capability with less un-sprung weight, the system uses 390-millimeter (15.4-inch) two-piece front rotors and 360-millimeter (14.2-inch) two-piece rear rotors. Six-piston Brembo calipers provide the stopping power up front, while the rear binders feature four-piston calipers.
The new Carbon Ceramic Matrix brakes provide the largest brake pad area ever offered on Viper and work in conjunction with the specially-tuned ABS and ESC to account for the extra grip provided by the increased downforce and specifically designed Kumho® tires. Detachable front brake ducts provide additional cooling to the brake calipers for optimum track performance.
Keeping the 2016 Dodge Viper glued to the road are four Kumho® Ecsta V720 high-performance tires designed specifically for the vehicle. Featuring a unique tread pattern and a unique raised ACR logo, the new tires have produce laps times that are 1.5 seconds faster than competition race tires. The low-profile front tires measure 295/25/19 and are mounted on wider 11-inch wheels, and when combined with the 355/30/19 rear tires, provide the largest combined tire patch available on any production car.
Aluminum bodied, double-adjustable coil-over Bilstein race shocks designed specifically for the Viper ACR 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, and the suspension package also provides more than three 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 1.5g 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.
The heart of the 2016 Viper ACR is the awesome, all-aluminum 8.4-liter V-10 overhead-valve engine, rated at 645 horsepower 600 lb.-ft. of torque – the most torque of any naturally aspirated sports-car engine in the world. Unique exhaust tips have been added to the side-mounted exhaust pipes to provide reduced exhaust pressure, and all Vipers are engineered to withstand severe track duty in ambient temperatures of 100 degrees Fahrenheit. Power reaches the pavement through the standard Tremec TR6060 six-speed manual transmission.
The Viper ACR features a host of exclusive appointments to its race-inspired interior, starting with the Alcantara-wrapped instrument panel cluster hood, lower instrument panel and door armrest panels. A new, ACR-exclusive Alcantara wrapped high-grip steering wheel with color racing stripe and unique badging sets the ACR apart from other production models. New high-grip seats also carry the Alcantara inserts, while the unique dash plaque is finished in carbon fiber.
