GM may drop its Pontiac and GMC brands to cut costs.
According to reports, GM's Buick, Chevrolet and Cadillac brands are now the only ones considered safe from the axe, while all other brands will either be sold or closed.
It is already widely known that GM is looking to offload Hummer, Saab and Saturn, while Opel/Vauxhall is said to be seeking independence, and now Pontiac and GMC are under threat.
Cutting the brands would also help GM reduce its dealer network. More details on this are available GM to axe more US dealers
In its submission for a federal loan last month GM said it wanted to retain GMC and Pontiac as niche brands, but this plan appears to have changed as the company races to restructure in an effort to avoid bankruptcy.
"We are continuing to assess our global operations, brand portfolio and nameplates, and will take further actions to more aggressively restructure our business," said a GM spokeman.
GM has been given until June to restructure by President Barack Obama.
