"The 2010 model year is going to be unique for the Dodge Viper in many ways both on and off the track, so to kick it off with production of our ultimate special-edition Viper ACR-X is our way of paying tribute to the performance engineering expertise of our SRT team, combined with the passion and dedication of Viper Nation, to keep the tradition going strong," Ralph Gilles, President and CEO, Dodge Brand, said in a release.

"With its amazing on-track performance, the Viper ACR-X is going to seriously turn the heads of all road-racing enthusiasts, whether it is the grassroots driver all the way up to the professional," added Gilles.
