According to the Associated Press, Ford's 2015 version of its best-selling F-150 pickup, which starts arriving at dealerships next month, will have a lot of aluminum rather than steel in its body.


Aluminum is lighter and more expensive than steel but just as tough. The new truck is the company's response to customers' requests for a more fuel-efficient pickup. Ford hopes the advantages outweigh customer doubts about the durability of aluminum or potential repair costs for the pricier metal.

It's a big risk. Morgan Stanley estimates F-Series trucks account for 90 percent of Ford's global automotive profit. The trucks have been the best-selling vehicles in the U.S. for 32 straight years. Last year, Ford sold nearly 100,000 more full-size pickups than General Motors.
