The widebody Challenger should look mean and have less trouble putting down its power.

The 6.2-liter supercharged Hellcat V8 could get even more hellacious soon based on these spy shots of the widebody Dodge Challenger testing. Wider fenders would accompany the meatier tires that would help the engine get more of its copious power onto the road. Currently, the powerplant can rapidly convert the rubber around the wheels into billowing smoke.

These upgrades would be part of the American Drag Racer, or ADR for short, package. The spy shots show two Challengers, one white and the other purple, testing the new components. Dodge doesn’t yet have the wider fenders in place on these examples, but the broader tires give a good idea of what to expect from the bigger fenders. The coupes would need to grow at least a couple of inches outward to cover the aggressive rubber. We could see this beast at dealers sometime next year.

Other than the wider fenders and tires, we don’t yet know much else about the ADR at this time. Suspension and brake upgrades wouldn’t be too surprising, though. There are even reports that Dodge can push the Hellcat’s output above 750 horsepower (559 kilowatts), but there’s no indication yet that the company actually plans to sell the engine with such an outrageous amount of power.

Dodge Challenger GT AWD Concept

Dodge gave us an idea of what to expect from a widebody Challenger with the GT AWD concept (above) at last year’s SEMA Show. The muscular fenders looked great on the retro-inspired body. Rumors indicate the production version of the all-wheel drive Challenger could enter showrooms in 2017.

The ADR and all-wheel drive Challengers could represent Dodge’s farewell to the current model.  A new one reportedly launches in 2018 or 2019, and it would use the same platform as the Alfa Romeo Giulia. The switch would potentially allow for a more nimble vehicle because the Giulia Quadrifoglio has no problem hustling around the Nürburgring at a rapid pace.
