It’s Ford Motor Co.’s biggest bet in decades: an aluminum-sided F-150 that could set a new industry standard – or cost the company its pickup truck crown. Ford is scheduled to start production of the 2015 F-150 Tuesday at its Dearborn Truck Plant, four miles from the company’s headquarters. It will arrive at U.S. dealerships next month. Ford thinks a more capable truck that is lighter and more fuel efficient will win buyers while its competitors struggle to catch up.
