For this reason, it seems likely that there will be two variants. One will be fitted with the 392 Hemi engine, since some racing classes and series do not allow supercharged engines, while the other model will reportedly be fitted with the Hellcat Redeye’s 6.2-liter supercharged Hemi with 797 horsepower. As with the Viper ACR of old, we expect beefy Brembo brakes, carbon fiber where feasible for reduced weight, and reworked suspension. Speaking of weight, the target is apparently to make the special-edition Challenger lighter than 4,000 pounds. In terms of the suspension, you can expect to be able to make your own adjustments for damping, rebound, height, caster, and camber. This won’t just be a limited-edition with some styling changes and stickers – it will be most at home on the track.
