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).

Detroit automakers keep their masks on to keep the factories running

United Auto Workers members leave the Fiat Chrysler Automobiles Warren Truck Plant in May. Fiat Chrysler along with rivals Ford and General Motors Co., restarted the assembly lines after several weeks of coronavirus lockdown. (AP)   DETROIT — When the coronavirus pandemic slammed the United States in March, the Detroit Three automakers shut their plants and brought their North American vehicle production to an unprecedented cold stop. Now, four months after a slow and sometimes bumpy restart in May, many General Motors, Ford and Fiat Chrysler Automobiles  factories are working at close to full speed, chasing a stronger-than-expected recovery in sales. So far, none of the Detroit Three has had a major COVID-19 outbreak since restarting production, even as the coronavirus is surging in Midwestern and Southern communities outside factory walls. "We have people testing positive, but it's not affecting operations," said Ford global manufacturing chief Gary Johnson. Keeping the pandemic at bay has pushed the automakers and 156,000 U.S. factory employees represented by the United Auto Workers into unfamiliar work routines and extraordinary levels of cooperation among the rival automakers that will have to be sustained for months to come. For automakers, the automakers' COVID response has been as much about instilling new habits as relying on new technology. Workers log their symptoms, or lack of them, into smartphone apps and walk past temperature scanners to get to their work stations. But company and union executives said masks, along with physical distancing, are the key to keeping assembly lines rolling. "The mask is the foundation" of protecting workers on the job, said Johnson. Complaints about masks Autoworkers are accustomed to wearing protective gear such as shatterproof glasses and gloves. Masks that cover the mouth and nose, however, were not standard equipment on auto assembly lines, and were a tough sell at first. "The biggest complaint is wearing a mask," United Auto Workers President Rory Gamble told Reuters. "A lot of our members perform physical tasks. Wearing the mask inhibits breathing." Beyond that, Gamble said, masks and distancing make it harder for workers to have conversations on the job or socialize during breaks. "ThatÂ’s pretty much out the window, and it makes for a longer day," he said. Masks make it harder for co-workers to read each other's expressions — often crucial in the noisy environment of a car plant.

Ranger in the USA, Alfa in Italy, and Volvo goes RWD | Autoblog Podcast # 780

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. They start off with this week's big news, including the official unveiling of the U.S.-market Ford Ranger and Ranger Raptor, some new RWD options from Volvo, and the potential production status of the Hyundai N Vision 74 concept. They also cover the discontinuation of the Mercedes-Benz CLS and the introduction of the latest RS model in Porsche's lineup, based on the 718 Spyder. From there, Byron talks about driving the new Alfa Romeo Tonale, and Greg digs into the new Lexus IS 500 F Sport Performance. After that, Byron talks about his Wankel-based discovery during his tour of Alfa Romeo's factory museum outside Milan.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.
