2016 Dodge Viper ACR White

Jump to Images

ACR is short for American Club Racer, and the Dodge Viper ACR is the track ready version of the formidable Viper road car. With 654 hp from its 8.4 liter V10, the Viper ACR doesn't perform just as well as you'd expect: it performs better. In a series of tests by driver Randy Pobst, the Dodge Viper ACR beat both the Porsche 918 Spyder and the McLaren P1 in lap times at Laguna Seca. And yes, there are lots of variables that come into play in any lap run, but for the Viper ACR to be so competitive against state of the art hypercars several times as much is testament to what an exceptional car this is.

At this point in time, all Dodge Viper production is expected to end in 2017, 25 years after its introduction. Released to much fanfare in the early days, the model has struggled to maintain sales in recent years. In 2014, only 760 Dodge Vipers were sold.

(from GeigerCars Press Release) Dodge Viper ACR 2016

The old American drag racing maxim “The bullshit stops when you line ‘em up” has travelled round the world countless times over the years in many different languages.

It is no wonder then that benchmark lap times on renowned racetracks have become a universally accepted measure of a race or street cars performance in relation to its peers.

Hailing from the country that coined the famous saying, the Dodge Viper ACR (American Club Racer), with the ‘Extreme Aero Package’ currently wears the lap record crown for a street legal sports car with the following achievements:

• A lap time 1.2 seconds faster than the Porsche 918 Spyder at Laguna Seca.

• Record production car lap times at 13 US race circuits.

• „Extreme Aero Package“ for outstanding downforce

The 887 hp Porsche 918 Spyder is acknowledged as one of the fastest hypercars in the world. To underline this, the all-wheel-drive Porsche set a 1:29.89 min lap time at the Laguna Seca Raceway in California, beating the
1: 30.71 min time of the 916 hp McLaren P1 by a good 0.8 sec, with Laguna Seca specialist Randy Pobst behind the wheel of both.

Even more impressive however, is the blazing 1: 28.65 min lap subsequently recorded by Randy in the Dodge Viper ACR, a time that put 1.2 seconds of clean air between it and the high-tech hybrid Porsche. The Viper ACR could not have asked for a more glorious baptism of fire.

To turn it into the razor-sharp street legal track tool that was to eventually set street legal sportscar lap records at 12 more US race circuits, the standard Viper underwent a very focused development programme jointly devised by the Dodge/SRT engineers and the team running the Viper GTS-R race cars in the United Sportscar Championship.

Rather than aspiring to be king of the autobahn, the Dodge Viper ACR instead highlights its motorsport genes, central to which is the outstanding handling and grip generated both aerodynamically and mechanically. Thus, a maximum speed over 285 km/h was not a priority.

For reasons of durability and reliability, the 8.4-liter V10 engine only gained an extra 5 hp for a total of 654 hp, with torque remaining at 814 Nm.

Under the big front air intake is a racecar-sized splitter, which creates positive downforce over the front axle. Supplementing this is a pair of ‘dive planes’ on each side of the front apron that also direct boundary layer air aft.

A 1.88 metre wide race grade carbon-fibre rear wing with Gurney flap and lateral air guides sits high in the airflow for maximum effect. Adjustable for angle of attack, this big wing adds significant downforce and directional stability. Further aiding downforce as well as ground effect the new rear apron features a carbon-fibre underbody diffuser with six vertical fins. These aerodynamic aids create nearly a tonne of downforce at top speed!

Made specifically for the Viper ACR, the Kumho Ecsta V720-high-performance tyres in 295/25R19 and 355/30R19 sizes help the Viper ACR generate up to 1.5 g of lateral acceleration. Optimising their grip on the tarmac is the job of the fully adjustable Bilstein coil-over suspension, whose bounce and rebound control can be independently adjusted. Spring rates are significantly higher than stock, and the car runs more negative camber to aid turn-in and stability.

Creating extreme deceleration is the task of the lightweight carbon-ceramic Brembo brakes, which also help to reduce unsprung weight. These use 390 mm cross-drilled vented discs clamped by six-pot callipers in front, and 360 mm discs with four-pot callipers at the rear. The ABS and ESP software has been remapped to take all the new hardware as well as track driving parameters into account.

While the Viper ACR is aimed at serious trackday junkies its cabin is not as Spartan as a full-blown racecars, and is actually well appointed with the sports seats and most other surfaces covered in leather and Alcantara. Carbon-fibre accents adorn the dashboard, door panels, and the flat-bottomed sports steering wheel features an orange ‘this way up’ band at the 12 ‘o clock position.

According to the media, production of the Dodge Viper will cease in 2017. If that prediction comes to pass then the 2016 Viper ARC will likely remain the pinnacle model of the cars glorious 25-year history.
