At the heart of the 2016 Viper ACR is the handcrafted, all-aluminum 8.4-liter 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 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.
