The October 2008 production and sales break-downs for GM are in their investor section. This contains information on what brands are selling what volume and what cars/trucks are selling the best from GM's inventory. Of the GM brands active in the US, and there are a few, Chevrolet was the best seller by a long shot:

  • 107,313 - Chevrolet
  • 21,109 - GMC
  • 13,054 - Pontiac
  • 9,541 - Cadillac
  • 8,583 - Saturn
  • 7,642 - Buick
  • 1,975 - Saab
  • 1,368 - Hummer

So what does GM sell the most of?

  • 31,689 - Chevrolet Silverado
  • 22,107 - Chevrolet Impala
  • 11,256 - GMC Sierra
  • 10,874 - Chevrolet Malibu
  • 6,788 - Pontiac G6

The Silverado and Sierra are the same truck just with a different badge. Of the Australian connection the Pontiac G8 (Holden Commodore) sold 1,082 units in October 2008 which isn't that much, but then, Saab sold a grand total of 1,659 in the same month. Of the Corvette marque there were 1,170 sold in October.

It looks like, that even with higher oil prices, the SUV and full size pickup is still the most popular of GM's offerings. I suspect those that are attacking the manufacturers in the US for not making fuel efficient cars that people want to buy are projecting what they think GM should be producing rather than the reality of what US consumers actually buy.

It is easy to forget that Toyota and Nissan both offer full size pickup trucks in the American market. They are locally built as well. The Ford F150 outsells the Toyota Camry. The Ford pickup is the best selling vehicle in America. (reply)
