GM announced the company will delay the redesign of SUVs and full-size trucks and they will focus on building lighter, fuel-efficient vehicles. GM's spokesman Tom Wilkinson said late Wednesday that GM is "looking at the whole product portfolio."

The entire U.S. auto industry is suffering as consumers, paying $4 per gallon for gasoline, shy away from heavier vehicles that burn more fuel than lighter, more-compact models.

Mr. Wilkinson said the company is considering how it can most effectively supply the U.S. market with fuel-efficient cars from its vast cupboard of global vehicle designs.

The auto maker will extend the life cycle of its current lineup of pickups and SUVs. Those vehicles -- known as the GMT900 lineup -- include the Cadillac Escalade SUV and the Chevrolet Silverado pickup. The new generation of trucks and SUVs weren't slated to hit the market until at least 2012, but development of these products drains precious resources at a time when GM is battling to satisfy customer tastes.
