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).

2015 F-150 launch to curb Ford profits?

Ford is making a big bet on aluminum with its new 2015 F-150, and it's possible that the decision will hurt the company financially, at least in the short term. After earning a record $8.6 billion in 2013, the Blue Oval does not expect to set another record in 2014. According to Automotive News, that's "largely attributable to F Series," says Bob Shanks, Ford's Chief Financial Officer.
To retool for the new F-150, Ford will idle its Dearborn Truck Plant in Michigan for 11 weeks and the Ford Kansas City Assembly Plant in Missouri for 2 weeks. "3 of the 13 overall weeks occur during what normally is our summer shutdown timeframe," said Mike Levine, Ford Trucks Communication Manager, in an email to Autoblog. The extra 10 weeks will be preparing for the more aluminum-intensive construction for the trucks and will mean over 2 months of no F-150s being made. For comparison's sake, Chrysler boss Sergio Marchionne just confirmed that the 200 plant in Sterling Heights, MI will be down for 30 days to retool for the new model, but obviously there are many more F-150 production variables than for the midsize sedan.
Levine notes that Ford is already running three shifts at both plants, and says the automaker has plans to ensure that there is adequate supply of the full-size pickups during the retooling process. The company does not want to suffer a shortage of the vehicle that accounted for 31-percent of its 2013 US sales and an even bigger percentage of its profits.
