As if the standard Viper was not aggressive enough, Dodge introduced the track-ready ACR at SEMA in 2014. The car’s 8.4-liter V-10 engine, capable of producing 645 horsepower and 600 pound-feet of torque, remained unchanged, although a number of other significant revisions were made to further enhance the model’s performance. For the first time with the Viper, the car was fitted with a Brembo-built braking system that used carbon ceramic brake discs. Handling was further improved with an adjustable suspension manufactured by Bilstein and a set of bespoke tires produced by Kumho specifically for the ACR trim level. A six-speed manual was Dodge’s sole transmission offering for the ACR, and a capable limited-slip differential helped manage power to the rear wheels.

The performance potential is cranked up to the max with the addition of the Extreme Aero Package, which the example on offer features. This option drastically increased the downforce thanks to a kit of removable aerodynamic devices fitted throughout the car. Up front, hood extractors and over-wheel-arch vents possess removable louver panels to relieve pressure. Two canards are fitted on each corner, and the carbon fiber splitter receives a detachable extension with support struts. Out back, a larger dual-element rear wing sits higher and farther back than on the standard ACR. In addition, it features vented endplates and a unique Gurney flap. The six carbon fiber diffuser strakes on the underside of the vehicle receive polyethylene extensions that maintain contact with the ground, helping to seal the crucial air flowing beneath the car. All together, these elements are capable of producing a thoroughly impressive 1,200 pounds of downforce at 150 mph.

As shown on the window sticker on file, the Viper ACR on offer is finished in Viper White exterior paint over a Black interior with Header Red contrast stitching. Additional options include the Extreme Aero Package and Header Red seat belts. A Carfax confirms the car was delivered new to an individual residing in Oklahoma. While under the care of this owner, the car acquired several thousand miles on the odometer and was maintained at a dealership in Tulsa. The original owner eventually parted ways with the Viper in 2023, and now just 6,212 miles show on the odometer at the time of cataloging.

With a road presence entirely unsurpassed by ostensible competitors such as the Corvette ZR1 and Porsche 911 GT3 RS, the Viper ACR was undoubtedly the ultimate American performance car during its production run. With many manufacturers looking towards electrification for their next generation of performance cars, it is unlikely a car like the Viper ACR will ever be produced again. As such, this tastefully specified example would make a striking addition to any collection.
