Dodge unveiled the third limited, special-edition version of the soon-to-be-discontinued Viper SRT10 sports car, dubbed ACR-X. Based largely upon the Viper SRT10 ACR, the new model is a turn-key, non-street legal, racer that's powered by a tweaked version of the standard Viper's 8.4-liter V10 that gains new headers and a low-restriction exhaust system, increasing output by 40HP to 640 horsepower.
The Viper SRT10 ACR-X's suspension has been upgraded and tuned specifically for track usage, while the sport car's weight is lightened by 160 pounds (73 kg) over the standard production model.
Dodge said that the car also features additional aerodynamic upgrades to improve downforce as well as to enhance stability and grip in high-speed cornering.
As a track racer, the Viper ACR-X comes with all the usual factory-installed safety equipment such as a factory-designed roll cage, fuel cell and race seat.
Dodge said that during a testing session of the ACR-X at Laguna Seca raceway last month, professional driver Kuno Wittmer from the SCCA Pro Racing SPEED World Challenge Touring Car Championship series, was able to run consistent 1:31.00 lap times around the 2.238-mile, 11-turn course.
This means that Wittmer's lap times were more than 3 seconds faster than the street-legal Viper SRT10 ACR which holds the production car track record at Laguna Seca raceway.
"The Dodge Viper ACR-X is incredible," said Wittmer. "After a short warm up, I was running lap times as quick as exotic GT race cars. I was blown away by the power and acceleration, and even more surprised at how the ACR-X navigated the challenging Laguna Seca corners and how friendly it was to drive at the limit."
The limited production 2010 Dodge Viper SRT10 ACR-X will go on sale in the States in Spring 2010 with prices starting from around $110,000.
