Unlike other pillared two-door sedans that use two side windows separated from the rear window by roof supports, Loewy created a roof rounded at the rear with a wraparound window system that provided a panoramic effect, similar to a railroad observation car. The curved window was achieved with four fixed panels of glass. The roof was supported by two wide pillars (sometimes called "B" pillars) immediately behind the doors and in front of the wraparound back window. The body style was originally named, simply, "5-passenger coupe"; however, for the 1949 model year it was renamed Starlight Coupe.
