The '''Chevrolet Omega''' is an [[executive car]] sold by [[Chevrolet]] for the [[Brazil]]ian 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 engineering|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-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 {{convert|4.1|L|cid|-1|abbr=on}} [[Chevrolet Turbo-Thrift engine#250|Chevrolet straight-six engine]] (CD) as used in the previous GM Opala albeit tuned by [[Lotus cars|Lotus]] and with electronic multiport fuel injection added.<ref>{{usurped|1=[https://web.archive.org/web/20100301235155/http://blog.hemmings.com/index.php/2010/02/25/chevrolet-omega-the-last-250/ Chevrolet Omega, the last 250 at Hemmings Blog: Classic and collectible cars and parts]}}</ref><ref>[http://carinfo.autold.com/car-chevrolet_omega-22-gls.html Chevrolet Omega 2.2 GLS specifications]</ref><ref>[http://carinfo.autold.com/car-chevrolet_omega-41-cd.html Chevrolet Omega 4.1 CD specifications]</ref> Both [[sedan (car)|sedan]] and [[station wagon]] (called Omega Suprema) [[Car body style|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.<ref>{{citation | url = http://gerpisa.org/ancien-gerpisa/actes/25/25-3.pdf | title = Globalisation and assembler-supplier relations: Brazil and India | journal = Actes du GERPISA | location = São Paulo, Sussex | last1 = Humphrey | first1 = John | first2 = Mario | last2 = Salerno | page = 52}}</ref> The CD version was offered the availability of the ''[[GM 4L30-E transmission|4L30-E]]'' automatic transmission as an option.
