Aluminum lightweighting does, in fact, save fuel

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. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

Ford previews updated Police Interceptor Utility for Chicago debut

With more law enforcement agencies across the United States alone than we'd care to count (or ever encounter), selling police cars means big business for American automakers, with Ford, Chevy and Dodge competing to fill the motorpools of every police department, sheriff's office and government agency in the land. For its part, Ford offers the Taurus-based Police Interceptor sedan and the Explorer-based Police Interceptor Utility, and it's preparing to unveil a revised version of the latter at the upcoming Chicago Auto Show in the same city where it's built. Dearborn hasn't given us much to go on with this teaser, showing just a darkened front shot of the vehicle in question with its emergency lighting all aglow. But it's fairly clear that the Interceptor Utility has been given many of the same updates applied recently to the Explorer on which it's based. That starts with the revised sheet metal, but considering that the Interceptor Utility exclusively packs V6 power, the 2.3-liter EcoBoost four that was one of the biggest updates to the civilian Explorer isn't likely to carry over. Ford does, however, promise that the revised Police Interceptor Utility will be "even better" than the model it replaces" and pack "more high-tech features." Related Video:
