On Monday Dodge released this sketch of the new Challenger that, in addition to the amazing spy shots caught by AutoWeek, give us a really good idea of how the newest muscle car on the block will present itself once it’s unveiled at the Detroit Auto Show. The automotive press has been fielding mixed reactions about the car’s design, though we’re pretty sure it’s sweet. The look is very retro, almost to the point where it’s not so much a reinterpretation of a past design but an old design itself. Some have also speculated about whether it will have two or four doors. The spy shots and the sketch indicate the concept will have a proper pair of doors, and we can’t imagine the company would field another four-door muscle car alongside the Charger. One thing’s for “almost” certain, this car is coming. It’s everything but official and we’re predicting the reaction to the Challenger concept in Detroit will be universally positive, if for no other reason than folks want to see the Big 3 go at it again in this arena.
