The Chevrolet Omega is an executive car sold by General Motors do Brasil for the Brazilian market. Replacing the Chevrolet Opala, which was a development of the Opel Rekord C, the original Chevrolet Omega was based on the Opel Omega A, and built locally between 1992 and 1998. After 1999, local production ceased, and GM imported badge engineered versions of the Holden Commodore from Australia.

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, the engines were upgraded to a 2.2 L four (GLS) and a 4.1 L six (CD) (from the previous GM Opala, but with electronic fuel injection added) respectively. The Omega quickly gained success in Brazil, where it was regarded as one of the most luxurious cars of its time. 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. Some funeral parlor owners chose the Omega Suprema as the preferred car for hearse-based modifications.

In 1999, with the Chevrolet Omega B, General Motors ceased local production in favour of importing a badge engineered version of the Holden Calais, with subsequent model changes mirroring those of the Australian counterpart. The original Omega B was equipped with the 3.8 L Buick V6 engine, developing 207 PS (152 kW), but the 2005 update received a new 3.6 L Alloytec V6. The second generation Omegas were only offered as a four-door sedan (the Commodore also had wagon and pickup variants), and identical Australian-made left-hand drive models were also exported as the Chevrolet Lumina.

For the fourth generation Chevrolet Omega C, General Motors again looked to Holden for the new model. The Omega C launched in mid-2007 is little more than a rebadged Holden VE Berlina, a member of the Commodore family[1]. It is available with the 3.6 L Alloytec engine.
