The Olds Cutlass S was introduced for 1968. Powering this beast were a 250 CID Chevrolet I6, 350 CID 2bbl Olds V8 or 350 CID 4bbl Olds V8. The nose was updated for 1969 and the generation lasted through 1972.
All Cutlass models were morphed into the colonnade look for 1973. The appearance was basically the same through 1975. Arguably the best looking Cutlass S was introduced for 1976 with rectangular headlamps and a slanted nose. It was clear that Oldsmobile made it for the Nascar Winston Cup circuit. The final year for the S model was 1977. The next year, the Cutlass Calais replaced it.
