When Dodge showcased the Viper ACR Concept at the 2014 SEMA Show, I began to wonder whether Chrysler finally realized that the ACR needs to return at the top of Viper lineup. Come 2015, and its seems the ACR Concept was just a teaser of things to come, as Dodge has just unveiled a new Viper ACR. The nameplate returns for the second time, after a five-year hiatus, with an aerodynamic package that’s arguably the most extreme in the Viper’s 22-year history.

The ACR, short for American Club Racing, was initially introduced in 1999, three years into the second generation of the V-10-powered sports car. Available as a coupe only, the ACR received an array of aerodynamic and mechanical updates for improved performance at the track. Discontinued for the third-gen Viper, the track-ready machine returned in 2008 with even more updates. In 2011, it lapped the Nurburgring track in 7 minutes and 12.13 seconds, now the sixth-fastest lap for a production car on the "Green Hell."

Whether Dodge is out to set a new benchmark at the ’Ring is yet unknown, but Dodge’s press release does speak about "unprecedented lap times." And judging by the new aero bits added to the ACR, it would be more than capable to improve the previous benchmark on the Nordschleife. Join me in the review below for more details on the 2016 Viper ACR.

Updated 11/04/2015: Dodge announced that its new 2016 Viper ACR established more track records than any production car in the world. The sports car certified lap records at 13 road courses, including world-famous Laguna Seca, Road Atlanta and Virginia International Raceway. At Laguna the ACR became faster than cars like Porsche 918 Spyder - which lapped the track in 1:29.89. A series of nine new video will offer you the chance to watch how some of this records were established.

Exterior

Not surprisingly, the styling of the new Viper ACR is very familiar. Not only is it nearly identical to the SEMA Show concept car, it’s also similar to the previous model sold from 2008 to 2010.

As seen in the past, the aerodynamic package on the ACR adds a carbon-fiber splitter, carbon-fiber canards on each side of the bumper, a race-spec vented hood, and fender gills. What sets the 2016 model apart from the concept car and the previous Viper is the extra pair of canards attached to the bumper. While the previous cars had one on each side, the new ACR received two.

Dodge claims the new aero package produces the highest aerodynamic downforce of any production car, quoting nearly one ton of downforce at 177 mph during testing.

Around back, a huge, carbon-fiber wing with aluminum stanchions provides additional downforce for enhanced cornering at high speeds, while the aggressive diffuser, also made from carbon-fiber, reminds us this car was developed by the same people who built the race-spec Viper GTS-R, an IMSA, GTLM-class winner in 2014. Dodge claims the new aero package produces the highest aerodynamic downforce of any production car, quoting nearly one ton of downforce at 177 mph during testing.

The ACR’s signature livery, also seen on the SEMA concept, rounds off the new sports car. The paint scheme consists of a thick gloss-black center stripe that flows from nose to tail, complemented by an offset Adrenaline Red stripe.

A bit of unexpected news comes from the customization department, as Dodge included the ACR in the "1 of 1" Viper Program. This option allows Viper ACR customers to have "more than 25 million build combinations" thanks to 8,000 exterior color options, 24,000 custom stripe colors, and 11 wheel options.

Do you still think you need to buy a Ferrari to have access to that kind of stuff?

Interior

Dodge hasn’t released photos of the ACR’s interior, but it’s safe to assume the Viper’s standard cockpit was revised with emphasis on weight reduction. With that in mind, I expect some of the vehicle’s convenience features, including the radio amplifier, speakers, and the carpet, to have been removed. Carbon fiber has likely replaced every bezel on the dashboard.

The race seats, steering wheel and the shifter have all been wrapped in Alcantara for better grip, as showcased in the SEMA concept. Likewise, the 2016 ACR features 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.

The "1 of 1" Viper Program enables buyers to select from an additional 16 interior trims.

Drivetrain

2016 Dodge Viper ACR High Resolution Drivetrain

Like its predecessor, the Viper ACR uses the same drivetrain as any other Viper in the current lineup. This means motivation is provided by the beastly 8.4-liter V-10 engine rated at 645 horsepower and 600 pound-feet of torque. Doing all the shifting is a Tremec TR6060 six-speed manual gearbox. Racers who don’t like rowing their own gears might as well take it to Chevy for an eight-speed Corvette Z06, as Dodge isn’t planning on offering an automatic transmission for the Viper anytime soon. And I like that!

No word on performance figures yet, but the reduced weight and tweaked chassis should shave a few tenths off the Viper’s standard 3.3-second, 0-to-60 mph sprint. I’d say the ACR wouldn’t find it hard to reach the same benchmark in 3.1 seconds, a bit quicker than the Corvette Z06’s 3.2 ticks with the manual transmission. The ACR’s top speed is likely identical to the Viper TA’s at 193 mph.

Chassis, Suspension and Brakes

2016 Dodge Viper ACR High Resolution Exterior
- image 629653

This is where the ACR stands out compared to other Vipers. Much like the aerodynamic package, the chassis was tuned to deliver maximum performance and withstand a full day at the track.

Dodge claims testing revealed the new rubber produces laps times that are 1.5 seconds faster than regular race tires.

Keeping the ACR on its best behavior is a set of aluminum-bodied, double-adjustable coil-over Bilstein race shocks specifically developed for this car, a suspension package that provides more than three inches of ride height adjustment, and unique suspension tuning. The ABS and five-mode ESC system was also specifically retuned for the ACR’s extra grip and extreme aerodynamic package.

Bringing this bruiser to a halt are Brembo’s carbon-ceramic Matrix brakes with 15.4-inch, two-piece rotors at the front and 14.2-inch, two-piece discs at the rear. The front brakes use six-piston Brembo calipers, while the rear brakes employ four-piston calipers.

The ACR’s outstanding grip comes from the Kumho Ecsta V720 high-performance tires, also designed specifically for this Snake. The tires feature a unique tread pattern and compounds for front and rear and Dodge claims testing revealed the new rubber produces laps times that are 1.5 seconds faster than regular race tires.

New Nurburgring record, anyone?

Prices

The 2016 Dodge Viper ACR is priced from 117,895 - excluding destination and gas guzzler tax.

Competition

Chevrolet Corvette Z06

Chevrolet Corvette Z06

Based on the seventh-generation Corvette Stingray, the Z06 features an extensive aerodynamic body kit, a number of race-bred internals, and a supercharged, 6.2-liter V-8 engine. In short, it’s the best U.S.-built competitor for the new Viper ACR.

The Z06’s engine sends a whopping 650 horsepower and 650 pound-feet of torque to the wheels, five horses and 50 pound-feet more than the Viper, and enables the Z06 to return some impressive, supercar-like performance figures. The coupe needs only 2.95 seconds to reach 60 mph from a standing start with the automatic transmission and 3.2 second with the manual. Top speed is 200 mph, also superior to the Viper ACR’s.

Besides being more powerful and slightly quicker, the Z06 is also significantly cheaper than the Viper ACR, retailing from $78,995. For the amount you’d spend on an ACR, you would get a fully optioned Z06 and save enough dough for a couple of fun-filled weekends at the track.

If you’re like me, you’ve probably been waiting for this moment ever since Dodge discontinued the previous Viper ACR in 2010. Arguably the most radical Viper for the road, the ACR just had to make a comeback, especially with the current Viper looking sexier than ever. On the other hand, it’s big, five-year gaps like these that make sports cars such as the ACR special and sought-after. Sure, it might not be as quick as the Corvette Z06, but its reputation as a lap-time busting machine will likely weight heavily in the eyes of American-built supercar enthusiasts. If you’ve been day-dreaming about parking a Viper race car in your driveway, than this is it!

  • Leave it
    • The Z06 is still more powerful and faster
    • Significantly more expensive than its main competitor

Press Release

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 ACR.

2016 Dodge Viper ACR High Resolution Exterior

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 – 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, 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.

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 have experienced nearly 1 ton of downforce at top speed of 177 mph.

The Extreme Aero Package includes a huge (1,876-mm 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 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 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 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 un-sprung weight. The system uses 390-millimeter (15.4-inch) two-piece front rotors and 360-millimeter (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 Viper. The brakes work in conjunction with ABS and ESC specifically tuned for 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 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 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 unique raised ACR logo.

The Viper ACR’s ABS and five-mode Electronic Stability Control system (Full-on, Sport, Track, Rain, 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 lbs./in. 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 due to 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,” added Kuniskis.

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 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.

‘1 of 1’ Viper Program Offers One-of-a-Kind Street-Legal Race Car
