This car was the top of the X-body line along with Buick's Apollo and Skylark, having more luxury trimming, more noise insulation, rear anti-roll bars, and other features not found on the Chevrolet Nova.

There were four basic Oldsmobile X bodied cars, the F-85( the base car), the Omega, Omega SX, and the Omega Brougham. During the 1975-76 model years, the top engine choice was a 350 cu. in. (5.7 Liter) V8 from GM's Oldsmobile division. During that time, the base engine was the 115 hp (86 kW) 250 cu. in. (4.1 Liter) inline-6 from Chevrolet, until 1977 when it was dropped in favor of the lighter 110 hp (82 kW) Buick 231 V6. It saw few changes through its life being limited mostly to the front end (3 different grilles) and to the rear lights, changing the number of lenses through the years. The Oldsmobile 260 (4.3-liter) V8 was available as an option from 1975-79.
