FactThe 1981 Sport Omega pioneered urethane plastic fenders, and the Omega was the only X-car to sell better in 1981 than in 1980.
The third-generation Omega moved to GM's heavily revised front-wheel-drive X-body for 1980, shared with the Buick Skylark, Chevrolet Citation and Pontiac Phoenix, built at Willow Run, Michigan, as a coupé and sedan until 1984. Engines were Pontiac's 2.5 litre Iron Duke four and the new corporate 2.8 litre V6, with a four-speed manual or three-speed automatic.

Plagued by the X-body's recall-prone brakes and suspension, the Oldsmobile Omega's sales cratered in its final year, down to just 52,986 cars built in 1984.

The 1981 Sport Omega pioneered urethane plastic fenders, and the Omega was the only X-car to sell better in 1981 than in 1980.

Its engines came from three GM divisions: a Chevrolet six, a Buick V6 or 350 V8, and Oldsmobile's own 260 V8.
Rivals
Same body, same money, other badges — tap any card to flip.

It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.

Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.

A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.

The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.

The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.

The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.

The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.

This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
