Based on the Opel Omega A, the Chevrolet Omega A debuted in Brazil in 1992 with a choice of two engines — a 2.0 L four-cylinder (GLS and GL trim) and 3.0 L six-cylinder (CD trim). From 1995, following the discontinuation of Omega A in Germany, the engines were upgraded to a 2.2 L four (GLS) and a 4.1 L (250 cu in) Chevrolet straight-six engine (CD) as used in the previous GM Opala albeit tuned by Lotus and with electronic multiport fuel injection added. Both sedan and station wagon (called Omega Suprema) body styles were available. The station wagon shared the exact powertrain configuration and trim options with the sedan versions. Some funeral parlor owners chose the Omega Suprema as the preferred car for hearse-based modifications.
In addition to the bigger engines, suited to local petrol quality, General Motors do Brasil had also deemed it necessary to beef up the suspension of the Omega to deal with Brazilian road conditions. The CD version was offered the availability of the 4L30-E automatic transmission as an option.
