The Oldsmobile Omega is a compact car that was sold from 1973 through 1984 by Oldsmobile. The name omega was used to imply the last, the end, or the ultimate limit of a set, in contrast to Alpha, the first letter of the Greek alphabet. There were two generations of Omegas, both badge engineered on Chevrolet models, and both using the GM X platform architecture: 1973–1979 - rear-wheel drive, related to the Chevrolet Nova. 1980–1984 - front-wheel drive, related to the Chevrolet Citation.
