• 2016 Dodge Viper ACR

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.

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?


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.


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

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?


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

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
