2016 Dodge Viper ACR Reveal Highlights


Tim Kuniskis – President and CEO, Dodge Brand – reveals the 2016 Dodge Viper ACR at Conner Avenue Assembly Plant in Detroit, Michigan on May 8, 2015.

The SRT engineering team that developed the 2016 Dodge Viper ACR is well-stocked with members who race their own cars, as well as learning 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.

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 fibre. Customers can choose between Silver or Header Red accent stitching throughout the interior.

Reconnaissable avec sa large bande noire centrale et une fine bande rouge latérale, courant sur la longueur de la caisse du capot avant à l’arrière jusqu’à l’aileron, le team a travaillé sur un Extreme Aero package :

Extreme Aero package: racing-first

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 have experienced nearly 1-ton of downforce at top speed of 284 km/h (177 mph).

The Extreme Aero Package includes a huge (1.8 metre wide) adjustable dual-element rear wing, rear carbon fibre 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. The Extreme Aero package delivers more than three times the downforce of the Viper TA (Time Attack) 2.0 package.

The rear carbon fibre 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 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.

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 un-sprung weight. The system uses 390-millimetre (15.4-inch) two-piece front rotors and 360-millimetre (14.2-inch) two-piece rear rotors. Front brakes use six-piston Brembo calipers while the rear brakes use four-piston calipers.

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 front and rear. In testing, the new tires produce laps 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 wheels. When combined with the 355/30/19 rear tires, these tires provide the largest combined tire patch available on any production car. On the sidewall of the new tires is a unique, raised ACR logo.

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 7.6 centimetres (3 inches) of ride height adjustment.

At the heart of the 2016 Viper ACR is the handcrafted, all-aluminum 8.4-litre V-10 overhead-valve engine, rated at 645 horsepower and 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. All Vipers are engineered to withstand severe track duty in ambient temperatures of 37 Celsius (100 degrees Fahrenheit) with a professional driver. Power reaches the pavement through the standard Tremec TR6060 six-speed manual transmission.
