Based on theOpel Omega A, the Chevrolet Omega A debuted inBrazil 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 (250 cu in)Chevrolet straight-six engine (CD) as used in the previous GM Opala albeit tuned byLotus and with electronic multiport fuel injection added.[1][2][3] Bothsedan andstation 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 their preferred car for hearse-based modifications.
In addition to the bigger engines, suited to local gasoline quality,General Motors do Brasil had also deemed it necessary to beef up the suspension of the Omega to deal with Brazilian road conditions.[4] The CD version was offered the availability of the4L30-E automatic transmission as an option.

In October 1998, with the Chevrolet Omega B,General Motors do Brasil ceased local production in favor of arebadged version of theHolden Calais (VT) sedan imported from Australia[6][7][8] (as would be the case for Middle East bound models, instead badgedChevrolet Lumina).
The Brazilian model sold in a single "CD" specification, based on the Holden Calais powered by theEcotec 3.8-liter V6 engine developing 148kw.[9] The VT II model came to Brazil in December 1999.[10]
On 18 May 2001, GM announced that the Omega CD would now be based on theVX Calais, designed and manufactured in Australia.[11][12][13] Although based on the Holden Calais, the Brazilian model instead featured the trunk lid from VX series base models (whose tail lamps did not extend into the trunk lid).
The next update was announced by GM on 28 April 2003, with the Omega CD now based on theVY Calais,[7] again in a single "CD" specification.[14]
GM announced a final update of Omega B on 9 March 2005, now based on theHolden VZ series,[15] powered by the new 3.6-literAlloytec V6 engine. It was again sold in a single "CD" specification, this time based on theVZ Berlina with some extra equipment from the VZ Calais.[16][17] Sales ended in 2007 with the arrival of the new Omega C.
