Ford will broaden the use of Alcoa's aluminum after seeing positive results this year.
When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging.
Americans, on average, have gained enough weight during the past 40 years to cancel out automakers' vehicle-lightweighting efforts such as using lighter components or removing spare tire, reflecting an additional challenge automakers face to meet progressively more strict fuel-economy and greenhouse-gas emissions standards. The information comes from the U.S. Centers for Disease Control and Prevention (CDC) in a recent Automotive News report.
