New Dodge Viper ACR: Literal Ton of Downforce

by David Zatz on

There have been rumors of a Dodge Viper ACR coming for some time, as reported by Allpar in the past. Today, the company officially launched the car in a ceremony at the Conner Avenue, Detroit, plant where all Vipers are built, largely by hand.

The Viper factory is one of the very, very few automotive plants still within the Detroit city limits, along with the Jefferson Avenue Jeep Grand Cherokee/Dodge Durango plant.

The car has better aerodynamics, tires, and race-oriented suspension tuning; a rear diffuser and carbon-fiber front air treatments; 2,000 pounds of  downforce (vs 1,000 pounds in the prior car); and a six foot dual plan adjustable rear wing. The rear diffuser runs all the way to the front axle, with adjustable straights. It can maintain 1.5 g in turns.

Since our original story was posted, Dodge has issued a press release which highlights the car’s new carbon ceramic brakes with six-piston calipers and tires specifically created for the Viper ACR — Kumho Ecsta V720 sized at 295/25R19 front, 355/30R19 rear. (The sidewalls are extremely small in both front and rear).

The adjustable dual-element carbon fiber rear wing, carbon fiber rear diffuser, hood with removable louvers, and detachable extension for the front splitter and more dive planes, are all part of the ACR Extreme Aero Package and do not seem to be standard. This combination delivers a sustainable 1.5 g of cornering during high speed turns, according to Dodge.

The race-tuned suspension has ten-setting, double-adjustable, coil-over Bilstein racing shocks with a unique race alignment with three inches of height adjustment.  Weight reduction for racing includes lightweight carpet, a minimal three-speaker audio system, manual seats, and the aforementioned lightweight brakes. Weight distribution, incredibly, is 50/50 despite the V10 engine.

Inside, buyers get Alcantara® leather with accent stitching. Like the Dodge Viper GTC, the Dodge Viper ACR has a “one of one” customization option.

Dodge CEO Tim Kuniskis said that the car was not designed for just running three laps, but “You can run the car at the track all day, and the performance doesn’t fall off.” This may be a jab at a high-performance Chevrolet whose performance has been shown to fall as the engine heats up.

Allpar News will have more photos later, and full coverage of the event on Monday. Production begins in the third quarter of 2015. The original Dodge Viper ACR was produced for the 1999 model year, around seven years after the Viper was first created; it too had an adjustable suspension and weighed 64 lb less than the normal car.

For additional photography, see Allpar’s current 2016 Dodge Viper ACR page. Note: the announcement indicated that the car had power and torque increases, but these were based on comparisons to the prior ACR, not to the standard Viper.
