Raced in NMCA competition by Josie Roush McClenaghan, the Challenger was reworked and lightened for competition around a supercharged 6.2L Hemi V-8 with a Whipple supercharger and 3-speed automatic racing transmission. Its competition equipment includes an adjustable RaceQuip single seat, roll bar structure, RJS racing harnesses, Holley EFI control panel, drag tires, and a parachute. The exterior carries race lettering, contingency decals, Hellcat badging, an SRT spoiler, and Josie Roush McClenaghan’s name on the side windows.
