We all know that 1970 was the first year of the Challenger. But did you know that the program was actually conceived back in 1966? Chrysler management decided to build a car to compete with the then newly-introduced Mercury Cougar. The Dodge division was tasked with coming up with such a vehicle. The program was headed up by Harry Cheeseborough, senior vice president of styling and product planning, but the body design belonged to Bill Brownlie, then chief of design in the Dodge studio. By 1967 no design had been decided upon, and the presentation meeting was fast approaching. As a last ditch effort, Brownlie had a clay model built from his drawings, and as it turns out, it was this body design that was approved, and it remained virtually unchanged for production. Do you guys notice anything missing on this car?
