After 1999, local production ceased, and General Motors do Brasil imported badge engineered versions of the Holden Commodore from Australia.

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.

The Brazilian model sold in a single "CD" specification, based on the Holden Calais powered by the Ecotec 3.8-liter V6 engine developing 200 PS (150 kW).

[14] GM announced a final update of Omega B on 9 March 2005, now based on the Holden VZ series,[15] powered by the new 3.6-liter Alloytec V6 engine.

The new Omega's specifications now reflected those of the Australian Holden Calais (VE Series II), except for specially tuned suspension settings for Brazil's road conditions.
