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 opens investigation into Ford Explorer PI brakes

This year more than most, it's pleasant when we can string together a few days without word of an automaker or the National Highway Traffic Safety Administration announcing a bunch of new recalls. It's seemingly been a little quiet on this front lately (barring a spider-related Suzuki issue revealed early today), but now we have word of the government safety agency opening a Preliminary Evaluation into the 2013 Ford Explorer Police Interceptor, a probe that could potentially affect an estimated 20,000 vehicles.
The issue being investigated concerns failures of the front brake hose on the vehicle that show "small splits in the hoses near the body side ferrule of the hose assembly," according to the agency, and the issue could result in longer stopping distances. The feds have reports of 13 malfunctions affecting 11 Explorer units. However, it's important to note that all of the incidents come from a single, unnamed metropolitan police fleet that operates 46 of them. According to The Detroit News, the failures generally took place between December and July.
NHTSA is investigating further to find if this is a more widespread issue than just this one fleet. Ford spokesperson Kelli Felker confirmed to us, "We are cooperating with NHTSA on this investigation, as we always do." Scroll down to read the agency's report.
