Next Dodge Viper ACR Could Land In 2014
The last Dodge Viper ACR (for American Club Racing) rolled off the assembly line in 2010, boasting the same 600 horsepower and 560 pound-feet of torque from its V-10 engine as standard Viper models. Weight on ACR models was reduced by up to 90 pounds by gutting the interior, while the suspension and brakes were upgraded for track use.

Supercar is a term used most often to describe an expensive high end car. It has been defined specifically as “a very expensive, fast or powerful car”. Stated in more general terms: “it must be very fast, with sporting handling to match”, “it should be sleek and eye-catching” and its price should be “one in a rarefied atmosphere of its own”
