4 Things That Make The 2016 Viper ACR The Fastest Street-Legal Viper Ever

Yes, you can even take the kids to school in it.

The Dodge Viper, many believe, is in a class all of its own. It's not a supercar for those looking for refinement. No, the Viper has always been something of a hard case, and that's precisely why it's cherished. But if you want the ultimate street-legal race car on the market, there's only one name: the 2016 Viper ACR. Production is set to begin shortly. So here are four things SRT engineers developed for this badass super snake that make it a hand-built piece of American awesomeness.


1. Aerodynamic Performance. It's called the Extreme Aero Package for a reason; it produces the highest aerodynamic downforce of any production car. On-track testing resulted in insane downforce numbers: 1,200+ pounds at 150 mph and 1,700+ pounds at 177 mph top speed, along with 12 percent more downforce over the base ACR on straightaways. This package adds a huge adjustable dual-element rear wing that's 62 percent larger (in top surface area) than what's offered on the Viper TA 2.0 package. Oh yeah, it also delivers more than three times the downforce.

2. Braking. Any track car is hard on its brakes, but the Viper ACR features new Brembo Carbon Ceramic Matrix brakes. Obviously they provide excellent braking performance, but also with unprecedented braking resistance, and greater handling capability through reduced un-sprung weight. They also have the largest brake pad area ever on a Viper.

3. Tires and chassis. Obviously high-performance tires are needed here, so Dodge fitted the car with Kumho Ecsta tires designed specifically with a unique tread pattern and compounds for front and rear. These tires have already been tested to shave 1.5 seconds off lap times over off-road, race-only tires. The five-mode Electronic Stability system has specifically been tuned to take into account the extra tire grip, and the aluminum bodied, double-adjustable coil-over Bilstein race shocks were specifically designed for the car.

4. The engine. This goes without saying. The all-aluminum 8.4-liter V10 is rated at 645 hp and 600 lb-ft of torque – the most torque of any naturally aspirated sports car engine in the world. SRT added unique exhaust tips to the side-mounted exhaust pipes in order to help provide reduced exhaust pressure.
