This Crazy Challenger Build Is Headed To The 2020 SEMA Show:

Take A Viper Chassis, 1970 Challenger Body, Hellcat Engine, And You Get...

With everything going on in the world right now, it hasn’t stopped the automotive aftermarket from developing vehicles for the 2020 Specialty Equipment Market Association (SEMA) show, which is still scheduled for Tuesday, November 3rd to Friday, November 6th in Las Vegas, Nevada. The show is always packed with new products and crazy, one-off vehicle builds.

For this year’s show, Hemi Autoworks and Ellsworth Racing are building this one-off 1970 Challenger-bodied car dubbed the “Highway Star”. While this looks like a heavily modified classic Challenger, there is a lot more going on than meets the eye. Underpinning this car is a GEN II Dodge Viper chassis that has been stretched by 13-inches, the build will also use the upgraded Viper-spec suspension, brakes, and cooling systems.

Under the (modified) hood is a modern powerplant coming in the form of the 707 horsepower supercharged 6.2-liter HEMI Hellcat V8, with a Kong Performance ported supercharger and FI Interchillers blower spacers. Backing that engine up is a built Viper-spec T-56 six-speed manual transmission with a triple-disc Mantic clutch setup and billet flywheel. Out back is a modified Viper differential running a 3.73 gearset.

While it started as a rusty shell, the 1970 Dodge Challenger body is being restored and will feature custom front and rear fenders, which increase overall width by one and a half inches, to accommodate the 295/30R18 front and 335/30R18 rear rubber. A Challenger R/T hood has also been modified to provide clearance for the tall Hellcat motor.

A functional front splitter, custom rear wing, a diffuser, and side-exit exhaust will also find their way onto the 1970 Dodge Challenger body as this car will be more than just a show vehicle. The completed car will also be raced in various events around the United States and we can’t wait to see it in action.
