The Challenger concept is a genuine four-passenger car. “You can sit up in the back seat,” said Castiglione. Compared to the original, the greenhouse is longer, the windshield and backlite faster, and the side glass narrower. All glass is set flush with the body without moldings, another touch the original designers could only wish for. The car is a genuine two-door hardtop — no B-pillar — with the belt line ramping up assertively at the quarter window just forward of the wide C-pillar.
Exterior details one might expect, like a racing-type gas cap, hood tie-down pins, louvered backlite and bold bodyside striping, didn’t make the “cut,” the designers feeling such assorted bits would detract from the purity of the monochromatic body form. But tucked reassuringly under the rear bumper are the “gotta have” twin-rectangle pipes of the dual exhausts.
