1955 Pontiac Strato-Star and Oldsmobile 88 Delta: Similar Concepts

The 1955 General Motors Motorama featured two concept cars that strike me as being variations on the same basic body concept -- a body that might well have been considered for future production.  Otherwise, what was the point of this exercise when distinctly different styling exercises exploring a wider variety of ideas could have been presented.

As it happened, the basic design shared by the two concept cars never entered production, though a few features did.

One concept car was the Pontiac Strato-Star (some background information here).  The other was the Oldsmobile 88 Delta that I wrote about here.

I cannot prove my hypothesis, given available information on the Internet and in my reference library, so the best I can do is offer evidence via the GM-sourced images below.

Showing the car with the passenger door closed.

Features to compare are: (1) front wheel opening; (2) fender lines and beltlines; (3) door cutlines; (4) rear end basic shaping.

The 88 Delta's passenger compartment greenhouse seems lower than the Strato-Star's, the the C-pillar / backlight window areas differ considerably.  The wide front wheel openings are impractical for daily use in non-desert climates.

The 88 Delta has a 120 inch (3048 mm) wheelbase, but I cannot find that of the Strato-Star, but it seems to be shorter.

Doors seem to be the same width, but the 88 Delta's greater length is found between the rear door cutline and rear wheel.  Note the similarity of the fender lines and especially the rear fender shapes.
