Why it matters
A turn-key, non-street-legal race version of the Viper ACR, combining the ACR's performance with the safety equipment of the Competition Coupe. It was built for the one-make Dodge Viper Cup series launched in 2010.
How rare is it?
Six separate kinds of rarity – never combined into one number.

History
Dodge announced the ACR-X on 3 June 2010 and said it built 25 units, all sold through Viper Race Headquarters. The cars were due to make their on-track debut in July 2010 in the ten-race Dodge Viper Cup, sanctioned by the Viper Racing League; the car was also designed for SCCA and NASA events.
