The Oldsmobile 88 Delta was concept car first shown at the 1955 GM Motorama.
The two-tone blue dream car featured a blue-tinted, brushed aluminum roof and blue-tinted glass. This car's fate is not known.
The car was a four-passenger close-coupled coupe just fifty-three inches high, mounted on a 120 inch wheelbase similar to that of the production 88. The Delta was designed to consider new materials and design features, many of which are taken for granted today: dual fuel tanks in the rear fenders, cast-aluminum wheels, anodized aluminum trim, a center console for radio controls and extra storage.
Styling was strictly Harley Earl, very rounded with the dipped beltline that would permeate the GM line by 1957-58 and the car was two tones of metallic blue.
