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).

Toyota again claims Corolla outsold Focus worldwide

Toyota isn't convinced the Ford Focus was the best-selling nameplate globally last year. Bloomberg reports that for the second time in seven months, both Toyota and Ford are laying claim to the title. Ford cites R.L. Polk & Co. data that says the automaker moved some 1.02 million Focus models in 2012 compared to just 872,774 Toyota Corolla units. But Toyota says the actual figure is closer to 1.16 million Corolla models.
Last year, Ford said it took the sales crown through the fist half of 2012 based on information from IHS Automotive, but Toyota pointed out those numbers left out models like the Corolla-based Matrix and Auris, as well as the Corolla Fielder and Scion xB-based Corolla Rumion. Whether or not Toyota's belief that all these cars should be counted in the Corolla bucket is accurate or not is seemingly up for debate... as is the question of why it matters so much to both parties.
This time around, Ford is holding the line that the Focus is the "best-selling nameplate," with Erich Merkle, a US sales analyst with Ford saying the company's figure is, "a pure number that is verified by a third party." Toyota, meanwhile, has requested clarification from Polk.
