The 2016 Dodge Viper ACR: A Sports Car Meant for Racing

Updated November 4, 2015

On May 8, 2015, at an event in the Conner Avenue Viper factory, Dodge pulled the cover off the 2016 Dodge Viper ACR - a turn-key racing car meant for sustained racing, complete with an adjustable aerodynamics package (optional). It comes at around $30,000 more than the standard Viper: $117,895 plus destination (likely $2,495) and gas guzzler tax.

The car has better aerodynamics and race-oriented suspension tuning including custom tires; 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.

With the aero package set for the full ton of downforce, the top speed is still a hefty 177 mph, providing a good speed with the traction to keep it safe, in the hands of a skilled, trained driver. (The top speed is higher when the downforce is not set as high.)

The car has 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 company said it was the fastest street-legal Viper ever released; ordering opened on May 11, 2015.

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 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.

2016 Dodge Viper ACR with and without the aero package

The Extreme Aero Package includes dual dive planes on each side of the front fascia, an adjustable chin splitter that extends way out away from the nose, louvers on the hood to vent air from the front wheel wells, a rear diffuser that reaches up towards the front of the car with removable portions that reach all of the way to the ground and the massive, adjustable dual plane rear wing.

The red Viper above is a 2016 ACR without the Extreme Aero kit. It still has a lower front splitter, but without the large adjustable extension. There are carbon fiber dive planes, but only one on each side; and there are no louvers in the hood to vent air around the front wheels. Finally, the red 2016 Dodge Viper ACR does not have the rear diffuser, and while it has a large rear wing, the standard ACR wing is sized between the Viper TA and the Extreme Aero Package wing. (There is a black ACR right next to it with the larger Extreme Aero wing for comparison.)

This red Viper ACR is the car that you can get for the starting price of $117,895 that we discussed yesterday.
