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).

NHTSA investigating Ford Fiesta for faulty door latches

The National Highway Traffic Safety Administration has opened a preliminary investigation on the 2011-2013 Ford Fiesta because the regulator has received 61 complaints from drivers, including one claim of an injury, about the doors on the subcompacts failing to latch and sometimes even flying open while driving. NHTSA has estimated that the problem could affect as many as 205,000 vehicles.
NHTSA is still gathering further data about the problem, but looking at the complaints so far, both front and rear doors appear to be potentially involved with the alleged failures. Among the reports, there are 12 claiming that the door opened while driving. Several also indicate the "Door Ajar" warning illuminating during this problem. The one purported injury happened when someone attempted to shut the door, and it bounced back.
Ford spokesperson Kelli Felker told Autoblog via email, "We are cooperating with NHTSA on this investigation, as we always do." Scroll down to read the report from NHTSA.
