Oldsmobile Omega
The Oldsmobile Omega is a compact car manufactured and marketed from 1973 to 1984 by Oldsmobile, as the brand's most affordable, entry level vehicle — across three distinct generations.
The first two generations of the Omega used rear-wheel-drive configuration, as a badge engineered variant of the Chevrolet Nova. The third generation was marketed from 1980 to 1984 in a front-wheel-drive, as a variation of the Chevrolet Citation.
The omega nameplate derived from the last letter of the Greek alphabet.
As a badge engineered variant of GM's X-body Chevrolet Nova clones, with 2-door coupe, 3-door hatchback, or a 4-door sedan body-stles, the Omega and the Buick Apollo were introduced in 1973, following the Pontiac Ventura's 1971 introduction and also sharing the Nova's body and mechanicals. The Omega was distinguished by the brand's split "waterfall" grille, unique rear trim and more upscale interior trim including woodgrain trim on the dash. Parking lights were directly below in the bumper.
Engine choices were the standard Chevy-built 4.1-litre (250 cid) I6 with a 3-speed manual transmission standard, with a 4-speed manual or a 2- or 3-speed automatic optional. The lone V8 was Oldsmobile's 5.7 L (350 cid) "Rocket" V8, which had a 4-speed manual as standard with the 3-speed automatic optional. V8 models with the fifth VIN digit being the letter "K" received a 4-barrel Rochester carburetor. All other V8 engines received the standard 2-barrel version. There were also 53 "Doctor Oldsmobile Omega" manufactured in 1973 in Van Nuys, California with V8 engines and marketed exclusively at Century Oldsmobile in Van Nuys. This decal option was canceled in 1974.
Changes for model year 1974 included revised trim levels, including a base model and a new upper-level Brougham S trim. The parking lights were relocated inboard below the grille instead of the headlights and there was a new rear bumper design meeting the federal 5-mph impact standards. The 2-speed Powerglide transmission was dropped.
This Omega was the top of the X-body line along with Buick's Apollo and Skylark, featuring more luxury trimming, more sound insulation, as well as rear anti-roll bars. The Omega was offered in F-85, Omega, Omega SX, and Omega Brougham trim levels. For model years 1975-76, the top engine choice was a 350 cu. in. (5.7 Liter) V8 from GM's Buick division. The base engine was the 115 hp (86 kW) 250 cu. in. (4.1 Liter) inline-6 from Chevrolet, until 1977 when it was replaced by the lighter 110 hp (82 kW) Buick 231 V6. It saw otherwise few changes during production, notably revisions to the front end (with three different grille designs) and rear lights. The Oldsmobile 260 (4.3-liter) V8 was available as an option from 1975 to 1979.
The third generation Omega used GM's heavily revised X-body platform, moving from rear- to front-drive for model year 1980. Engine choices included Pontiac's Iron Duke inline-four engine and the new corporate 2.8 L LE2 V6 designed specifically for this platform. Transmissions were the 4 speed manual or the TH125 3-speed automatic.
