2008 Dodge Viper SRT10 ACR

So what makes the new ACR so special? Even the slightest glance will tell you this is no ordinary Viper. This particular car came in Viper Black with the unique two-tone paint scheme. The ACR can also be ordered in Viper Red, Viper Violet, Viper Bright Blue Metallic and Viper Very Orange, with only the Black and Red having the option of the two-tone paint. I haven't seen the ACR in anything but Red or Black, and can't imagine ordering it any color combo besides the one seen here.

But enough about paint schemes; the ACR is about one thing and one thing only: functionality. More specifically, putting down all that power from the 8.4-liter V10 to the pavement. To do this, the SRT team focused on aerodynamics, the result of which can be seen at both ends of the car. Up front is a carbon fiber splitter and dive planes that have been specially designed to increase downforce and reduce drag. An extension for the front splitter can also be added for increased aerodynamics at the racetrack. At the rear is an adjustable wing also made of carbon fiber that was specially formed using Computational Fluid Dynamics. So just how much downforce does the ACR produce? Try 1,000 pounds at 150 mph. That's ten times what the standard Viper coupe produces.

Additional traction is provided by massive Michelin Pilot Sport Cup tires (295/35ZR/18 front, 345/30ZR/19 rear) that are just barely approved for street use. The ACR also benefits from a track-tuned suspension consisting of KW adjustable coilovers and a stiffer front stabilizer bar. The coilovers can be adjusted without removing the wheels, which means that making the switch between street and track settings is an easy task.
