(CBS/AP) DETROIT - Ford says it will make 40,000 additional cars and trucks this year by cutting a week out of the normal summer shutdown at 13 factories.
Auto plants normally close for two weeks around the July 4 holiday to switch production to the next model year.
But Ford says the plants will close for only one week in order to keep up with rising demand for the company's vehicles.
Plants that will close for just a week include factories in Canada and in Illinois, Michigan, Missouri, Ohio, and Kentucky.
Through April, U.S. auto sales ran at an annual rate above 14 million. Last year sales were only 12.8 million. Ford sales are up 16 percent so far this year.
