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. 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.

Chevrolet Omega (sedan) and Suprema (station wagon) was powered by 2.0 L I4 or 3.0 L I6 Opel engines until 1994. Since discontinuation of Omega A in Germany, General Motors do Brasil needed a new engines. The 2.0 L I4 was replaced by 2.2 L I4 engine, and the 3.0 L I6 was replaced by 4.1 L (250ci) Chevrolet Straight-6 engine, which was tuned by Lotus and equipped with multiport fuel injection.^[1][2][3] The CD version was offered the availability of the 4L30-E automatic transmission as an option.

2000–2002 Chevrolet Omega

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.

Powertrain:

Engine	Power	Torque	Transmission
3791 cc Ecotec V6	152 kW (207 PS) (in version imported to Brazil this engine had a power of 200 PS)	305 N·m (225 ft·lbf)	4-speed GM 4L60-E automatic

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. It was available with the 3.6 L Alloytec engine.^[5] Due to the global financial crisis, imports ceased in 2008.^[6]

Omega (facelift)

After the Omega was discontinued in 2008, the Omega was rereleased in September 2010. The first 600 exports of the new model will be Omega Fittipaldi Edition named after Brazilian motorsport legend Emerson Fittipaldi. The new model has much the same specification level as the Holden Calais. The Omega has a specially tuned suspension to handle the poor quality roads often found in Brazil. This updated model carries over much of the same updates as the Holden VE Series II Commodore had, including the new Holden IQ audio system.^[7]

Lumina^[8]

In Arabia the Holden VE Commodore is sold as the Lumina. Offered in three different trims LTZ (Calais), S (SV6) and SS. The LTZ and S comes standard with a 3.6L Alloytec V6 and a 6-speed automatic transmission for the S and 4-speed for the LTZ , while the SS comes standard with 6.0L Alloytec V8 with the option of Active Fuel management. A 6-speed manual is standard with the option of a 6-speed Automatic on SS.

The LTZ is the luxury model including leather seats, six disc CD player, eight-way drivers adjustable lumbar support and duel zone climate control. While the S and SS focus on sportiness both having sport body kits, projector headlights and sport tail lights. The SS though has leather seats and is the only one out of all three trim levels to have bluetooth phone connectivity.

Lumina models sold in South Africa received updates for the 2011 Model Year. These changes were introduced to coincide with the release of the Series II Holden Commodore. Changes include revised bumpers, these is a chrome moulding above the number plate on the boot lid, refreshed alloy wheel designs and the Holden IQ system. Also the SSV model was introduced.^[9]
