Meanwhile, attempting to cut costs, General Motors ( GM) was halting construction of a plant tied to one of its most important projects, the Volt. Ford ( F) also said it will shut down 10 plants for an extra week in January because of sluggish sales. At a recent meeting, Chrysler dealers told company officials that "they have many willing buyers " but are unable to close the deals, due to lack of financing," Chrysler says. "The dealers have stated that they have lost an estimated 20 to 25 percent of their volume because of this credit situation."

At Ford, a company spokeswoman said Wednesday it will shut down 10 of its North American assembly plants for an extra week in January. Spokeswoman Angie Kozleski says the normal two-week holiday shutdown will be extended to Jan. 12 at all operating assembly plants except those in Claycomo, Mo., near Kansas City, and the Dearborn, Mich., truck plant. Ford will also extend the shutdown at some engine, transmission and parts stamping plants, or temporarily shut portions of them to match cuts at the assembly plants, she said. GM said Wednesday it was delaying construction of a new engine factory in Flint, Mich., in an effort to conserve cash. The plant is to make 1.4-liter engines for the Chevrolet Cruze and the Chevy Volt plug-in electric car, two key products in the century-old automaker's plan to turn itself around after relying on highly profitable truck and SUV sales.
