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).

Ford Escort returns... as a concept

Ford is kickin' it old school at the Shanghai Motor Show for 2013 with a new Escort Concept - "a name that stirs up thoughts of basic, affordable transportation rather than great driving dynamics or bold design" as we said in our initial preview of the small C-segment sedan. Or, as Ford puts it, "Customers in China described seeking a vehicle that is stylish - but not one that is arrogant or pretentious." Potato, potahto...
It's an interesting amalgam of design notes with Ford's recent and stylish hexagonal grille up front, flanked by some pretty busy LED light clusters and chrome-trimmed air intakes at the lower extremities of the fascia, but the Escort Concept is not altogether unattractive. Besides its external appearance, we really don't have much information to report - Ford has not yet hinted at what may be powering this little machine, but we'd expect something with four cylinders and less that 2.0 liters of displacement sending a modest number of horses to the front tires.
It probably goes without saying, but we don't expect to see this Escort make its way to the United States, since we already have the Focus and the Fiesta battling it out in the econobox segment. That said, it's very likely to spawn a production model that will roll out here in China and in other developing market where multiple C-segment entries are becoming increasingly common.

Ford expands air bag recall nationwide

Ford Motor Co. has agreed to government demands to expand a driver's side air bag inflator recall to the entire U.S. The move announced Thursday adds 447,000 Ford vehicles to the list of those recalled due to driver's inflators made by Japan's Takata Corp. The inflators can explode with too much force, spewing shrapnel into drivers and passengers. Ford's action puts pressure on BMW and Chrysler, the only two automakers that haven't agreed to national recalls. The National Highway Traffic Safety Administration made the demand of five automakers, saying the inflators are dangerous. Honda and Mazda already took their recalls national. Previously the recalls were limited to high-humidity states mainly along the Gulf Coast. The Ford national recall covers certain 2005 to 2008 Mustangs and 2005 and 2006 GT sports cars. The company also announced it would recall the same cars in Canada, Mexico and a few other countries. Thursday's announcement brings to just over 502,000 the number of Ford vehicles under recall for Takata driver's side air bags. The company said it knows of one accident and injury from the problems, in a 2007 Mustang in North Carolina. Dealers will replace the inflators at no cost to customers. Last month, NHTSA demanded that Takata and the five automakers recall driver's inflators across the nation.Takata and Chrysler have refused and could face legal action. BMW says it's still evaluating the demand. Takata hired the New York public relations firm Sard Verbinnen & Co. and took out full-page advertisements Thursday in newspapers including The New York Times, The Wall Street Journal and three German publications. The ads, featuring a letter from Chairman and CEO Shigehisa Takata, said the company will work with NHTSA and automakers to expand the recalls by increasing production capacity for replacement air bags. The company said it's exploring whether other companies' air bags can be used in replacement kits, and it's increasing testing to find the exact cause of the problems. "Takata will work in unison with automakers to advance our common goal of putting the safety of customers first," the letter said. But in documents filed with NHTSA, Takata refused to do a national recall, saying it's not supported by testing data. The company also said NHTSA didn't have the authority to order a parts supplier to do a recall, and that only automakers can conduct them.
