Deep Purple 1970 Challenger SEMA Build

Deep Purple 1970 Challenger SEMA Build

Project “Highway Star” is a 1970 Dodge Challenger with a mix of Viper and Hellcat parts. The goal is to create a vehicle that turns, stops and accelerates on a world class level. This will be achieved by combining the timeless lines of the ’70 Challenger with track proven Viper suspension and a powerful Hellcat 6.2 HEMI engine. This is one car that will get a lot of attention.
