The Viper ACR (American Club Racing) model was introduced in 1999, three years into the second generation of the sports car. Available only as a coupe, the ACR received a host of aerodynamic and mechanical enhancements developed for the track. A revised front bumper, a vented hood and a fixed rear wing were the main body highlights, while a stiffer, adjustable suspension improved its handling. Likewise, the 8.0-liter V-10 of the second-gen Viper had its output increased by 10 ponies to 460 horsepower for the ACR. Curb weight was reduced by more than 50 pounds. The third-gen Viper didn’t offer an ACR version, but the track-ready sports car returned in 2008 with even more updates. But unlike its predecessor, the new ACR didn’t have any engine modifications as the 8.4-liter V-10 kept its stock 600 horsepower and 560 pound-feet of torque. In 2011, a 2010 Viper ACR lapped the Nurburgring track in 7 minutes, 12.13 seconds. The sports car remains the sixth fastest production car on the "Green Hell" as of 2014. The 2010 model year was the last year for the ACR, but as we approach 2015, Dodge is showcasing an ACR Concept based on the fifth-generation model at the SEMA Show.

Could this mean the track-spec Viper is returning after a four-year absence? Dodge has yet to confirm it, but the concept car looks very familiar and ready to hit the assembly line. Check out the details after the jump as we wait for Chrysler to release more photos of the new ACR.

Dodge has released only one photo of the Viper ACR as of October 2014, but the image is enough for us to realize this concept car got the same treatment as the production vehicles based on previous Vipers. The front fascia updates are awfully familiar, as they include a carbon-fiber splitter, carbon-fiber canards on each side of the bumper, a race-spec vented hood, and fender gills. Around back, a large, carbon-fiber wing with aluminum stanchions provides additional downforce for enhanced cornering at high speeds.

As with all ACR Vipers, the concept sits on lightweight, 19-inch wheels shod in high-performance tires. Additionally, a new braking system with massive, 15.4-inch, carbon-ceramic, two-piece rotors and Brembo six-piston calipers provide much-needed stopping power. The brakes are cooled by carbon-fiber ducts in the front bumper, which speaks volumes about Dodge’s efforts in reducing the ACR’s curb weight as much as possible.

Rounding off the ACR Concept is the nameplate’s signature livery. Finished in white, the body is adorned by a thick gloss-black center stripe that flows from nose to tail, with an offset Adrenaline Red stripe adding a dash of color and completing the familiar paint scheme.


There are no photos of the Viper ACR Concept’s interior, but Dodge claims it puts an emphasis on weight reduction. Most of the vehicle’s convenience features, including the radio amplifier, speakers, and the carpet, have been removed, while carbon fiber replaces every bezel in the cockpit. The race seats, steering wheel and the shifter have all been wrapped in Alcantara for better grip.

Other unique features include a Header Red stripe for the 12-o’clock position of the steering wheel, a Stryker badge and a heritage ACR instrument panel badge with a carbon-fiber inlay. Accent stitching is there to remind us the ACR is based on the road-legal Viper.

There’s no word on what lurks under the ACR’s hood, but it’s safe to assume it’s the same 8.4-liter, V-10 engine currently offered in the standard Viper. For 2015, the mill has been updated to deliver 645 horsepower and 600 pound-feet of torque, a five-pony improvement over last year’s model.

Although it’s likely that the Viper ACR Concept comes with no additional horsepower, the reduced weight and tweaked internals should improve the sports car’s 0-to-60-mph time, with the standard 3.3-second sprint reduced to 3.2 or even 3.1 seconds.

Being only a concept car, the Viper ACR comes with no pricing information. However, it’s very likely that the SEMA Show vehicle previews a production version scheduled to arrive sometime in 2015. That’s when we’ll find out more about the ACR’s sticker.

As things stand, the Viper ACR Concept is nothing but a previous-generation model updated to fifth-generation visuals. Although only a concept car as of this writing, this Viper ACR could mark the return of Dodge’s track-ready sports car after a four-year absence. Now that the Viper is sold with a hefty, $15,000 rebate, we have reason to hope that a production ACR could help Dodge build on the Viper’s exclusivity and move more units in the future.

It’s difficult, but yes, you can improve the ultimate hand-built American exotic supercar. For a blueprint, look no further than the Dodge Viper ACR Concept.

Ready to strike at the track, the Dodge Viper ACR Concept sports an aggressive carbon fiber front splitter and a competition rear wing anchored to the Snake’s steel skin by sculpted aluminum stanchions. Many development hours in the wind tunnel achieved balance between the wing and stanchions, as well as how these elements work in conjunction with the front splitter to maximize downforce. Carbon fiber dive planes on the front fascia and hood heat extractors flanking the front fenders pour on even more aero downforce and aggressive styling cues. All of these lightweight carbon fiber elements work in unison to strike the perfect balance of maximum downforce for tight cornering and high speed maneuvers on the track.

The Dodge Viper ACR Concept races on satin black lightweight 19-inch front and rear wheels, with massive 15.4-inch Carbon Ceramic two-piece rotors with Brembo six-piston brakes. Brakes are kept to optimal temperature levels through carbon fiber brake duct openings in the front fascia. Differential cooler ducts rearward of the side windows supply fresh cool air to the differential for optimal performance. The signature ACR-style white paint is highlighted by a gloss black center stripe, accompanied by an offset Adrenaline Red stripe that flows from tip to tail, encompassing the competition spoiler with accented stanchion and end cap. The iconic heritage ACR side sill badge and Stryker front nose badge signify that this Viper is certainly a force to be recognized.

The race-inspired interior of the Dodge Viper ACR concept puts an emphasis on weight reduction for superior performance with unique styling cues that express its racing thoroughbred pedigree. Only the bare necessities remain as radio amplifier, speakers, carpet and NVH treatments have been removed to take advantage of every ounce. Carbon fiber virtually fills the cabin as every possible bezel has been replaced with this space-age lightweight material. Alcantara suede-wrapped steering wheel, shifter and seats provide ample grip to fully exercise its modified race suspension with razor sharp agility through the most demanding turns. A Header Red stripe that adorns the 12 o’clock position of the steering wheel provides an emotional connection to the exterior through the Adrenaline Red body stripe. Header Red accents carry over from the unique “Stryker” steering wheel badge to the iconic heritage “ACR” instrument panel badge with carbon fiber inlay, and are harmoniously joined by full interior accent stitching.
