GM to Build Ethanol-Fueled Trucks

General Motors Corp. will build full-size pickup trucks that can run on an ethanol-gasoline blend, and the largest auto maker said Monsanto Co. ordered 50 of the alternative-fuel vehicles.

The auto maker plans to begin building the Chevrolet Silverado and GMC Sierra pickups early next year. The trucks can run on E85, a blend of 85% ethanol with gasoline, or on just gasoline. Ethanol, a form of alcohol that can be made from corn and other crops, pollutes less than gasoline.

General Motors shares fell 37 cents to close at $48.24 on the New York Stock Exchange.
