The Chevrolet Omega is an executive car sold by Chevrolet 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. From 1998 to 2011, after local production ceased, General Motors do Brasil imported badge engineered versions of the Holden Commodore from Australia.
Omega A
Based on the Opel Omega A, the Chevrolet Omega A debuted in Brazil in 1992 with a choice of two engines—a 2.0-liter four-cylinder (GLS and GL trim) and 3.0-liter six-cylinder (CD trim). From 1995, following the discontinuation of Omega A in Germany, the engines were upgraded to a 2.2-liter four (GLS) and a 4.1 L Chevrolet straight-six engine (CD) as used in the previous GM Opala albeit tuned by Lotus and with electronic multiport fuel injection added.[1][2]
