The Oldsmobile 88 is a full-size car produced from 1949 until 1999.
All GM B-body full-size cars were completely restyled and enlarged for 1971, but continued to ride on a 124-inch (3,150 mm) wheelbase. It was available as a pillared four-door Town Sedan, two-door and four-door Holiday hardtops and a convertible. Series models for 1971 included the base Delta 88, Delta 88 Custom and Delta 88 Royale, the latter inheriting the convertible body style previously offered on the base Delta 88. All models received fuselage styling somewhat similar to what Chrysler Corporation introduced on its 1969 models, and new rooflines with a more squared off greenhouse for Town sedans and more rounded lines for Holiday sedans and coupes – the latter receiving reverting back to a semi-fastback format.
For 1973, wider and lower split waterfall grilles flanked a new federally mandated 5 mph (8.0 km/h) front bumper on all Delta 88 models and larger one-piece rounded rectangular taillights replaced the four-segmented lights of 1972. Engine offerings included a standard 350 Rocket V8 with two-barrel carburetor (150 net horsepower) or optional 455 Rocket V8 with four-barrel carburetion and 215 hp (160 kW) with single exhaust or 250 hp (186 kW) with dual exhausts. Model offerings were the same as 1972 with the Delta 88 Royale series now including the sole Olds convertible offering following the demise of the intermediate Cutlass Supreme convertible after 1972.
