GM closing 4 truck and SUV plants

General Motors is closing four truck and SUV plants in the U.S., Canada and Mexico as surging fuel prices hasten a dramatic shift to smaller vehicles.

CEO Rick Wagoner said Tuesday before the automaker's annual meeting in Delaware the plants to be idled are in Oshawa, Ontario; Moraine, Ohio; Janesville, Wis.; and Toluca, Mexico. He also said the iconic Hummer brand will be reviewed and potentially sold or revamped. Wagoner said the GM board has approved production of a new small Chevrolet car at a plant in Lordstown, Ohio, in mid-2010 and production of the Chevrolet Volt electric vehicle in Detroit.

Wagoner announced the moves in response to slumping sales of pickups and SUVs brought on by high oil prices. He said a market shift to smaller vehicles is permanent.

The moves will save the company $1 billion per year starting in 2010. Combined with previous efforts, GM by 2011 will have cut costs by $15 billion a year compared with 2005, Wagoner said.
