The next chapter in the history of the ultimate street-legal, track-focused, hand-built American supercar begins with the return of the new 2016 Dodge Viper American Club Racer (ACR).

Certified for public roads and engineered to wring every last hundredth of a second out of road course lap times, the 2016 Dodge Viper ACR combines the latest in aerodynamic, braking and tire technology – a recipe designed 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 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 of 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 well stocked with members who race their own cars, and who have 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, capturing the GTLM class driver and team championships in 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.

Ultimate aerodynamic performance
The 2016 Dodge Viper ACR with the available Extreme Aero package produces the highest aerodynamic downforce of any production car. During on-track testing, development engineers experienced nearly a ton of downforce at top speed of 177 miles per hour (283 kilometers per hour).

The Extreme Aero Package includes a huge (1,876-millimeter 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 airflow 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. The Extreme Aero package delivers more than three times the downforce of the Viper TA (Time Attack) 2.0 package.

The rear carbon fiber diffuser extends forward of the rear axle. It 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 to provide additional downforce. The detachable front splitter extension and dive planes work with the rear aero treatment to provide outstanding grip and balanced performance on the track.

Ultimate brake performance
Track duty can punish the brakes. The 2016 Dodge Viper ACR features new Brembo Carbon Ceramic Matrix brakes for optimum braking performance with unprecedented brake fade resistance, and greater handling capability through reduced unsprung weight. The system uses 390-mm (15.4-inch) two-piece front rotors and 360-mm (14.2-inch) two-piece rear rotors. 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 ever on a Viper. The brakes work in conjunction with anti-lock brakes (ABS) and electronic stability control (ESC) specifically tuned for the ACR to take into account the extra grip provided by the additional aero and specifically designed Kumho tires. Detachable front brake ducts provide additional cooling to the brake calipers for optimum track performance.

Tire, Chassis Combo Keeps Viper ACR Glued to the Road
The 2016 Dodge Viper ACR is fitted with Kumho Ecsta V720 high-performance tires designed specifically for the car with unique tread pattern and compounds for the front and rear tires. In testing, the new tires produce lap times that are 1.5 seconds faster than off-road only race tires.

Low-profile front tires measure 295/25/19 and are mounted on wider 11-inch wide wheels and when combined with the 355/30/19 rear tires, provide the largest combined tire patch available on any production car. On the sidewall of the new tires is a uniquely raised ACR logo.

The Viper ACR’s ABS and five-mode ESC system (Full-on, Sport, Track, Rain, and Full-off modes) 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 pounds per square inch 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 because of 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,” Kuniskis said.

Awe-inspiring V-10 Powertrain
At the heart of the 2016 Viper ACR is the handcrafted, all-aluminum 8.4-liter V-10 overhead-valve engine, rated at 645 hp and 600 lb.-ft. of torque – the most torque of any naturally aspirated sportscar engine in the world. Unique exhaust tips have been added to the side-mounted exhaust pipes to provide reduced exhaust pressure. All Vipers are engineered to withstand severe track duty in ambient temperatures of 100 degrees Fahrenheit with a professional driver. Power reaches the pavement through the standard Tremec TR6060 six-speed manual transmission.

ACR-exclusive Interior Appointments
The instrument panel cluster hood, lower instrument panel and door armrest panels of the race-inspired interior are wrapped in unique alcantara suede. 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. Customers can choose between silver or Header Red accent stitching throughout the interior.

“1 of 1” Viper Program Offers One-of-a-Kind Street-Legal Race Car
Applying Viper’s exclusive “1 of 1” customization program to Viper ACR allows customers to have more than 25 million build combinations to create their one-of-a-kind Snake from the ground up. With 8,000 exterior color options, 24,000 custom stripe colors, 11 wheel options, 16 interior trims and seven aero packages, three brake packages and four suspension options, there are more than 25 million ways for buyers to customize their one-of-a-kind Dodge Viper.
