The two-door model Challenger takes many cues from the 1970 model (the most sought after by collectors), including floating headlights, ribbed black seating, a hood with black trim, a 6.1-liter Hemi engine with six-speed manual transmission and a pistol grip shifter, and the general look and feel; designers had a 1970 model in the studio as they created a concept. "We wanted to do a muscle coupe that connects with the American heritage," said Tom Tremont, Vice President—Advance Product Design, "but instead of merely re-creating that car, the designers endeavored to build a Challenger most people see in their mind's eye—a vehicle without the imperfections like the old car’s tucked-under wheels, long front overhang and imperfect fits. As with all pleasurable memories, you remember the good and screen out the bad."
