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).

BMW to follow Honda back into F1?

The economic downturn wrought devastating effects on motor racing. Formula One alone lost half its engine suppliers when Honda left at the end of the 2008 season, and both BMW and Toyota followed at the end of 2009. But things are looking up again. Cosworth may have dropped out this season, reducing the engine suppliers to three: Ferrari, Renault and Mercedes, the latter of which admits that it may have left had the engine formula not changed. But Mercedes has stayed and is dominating the championship. Honda is coming back next season. And word around the paddock is it may not be the only one.
According to Giancarlo Minardi - founder of the team now known as Scuderia Toro Rosso - BMW engineers have been conspicuously spotted lately at F1 test sessions and grands prix, lending to speculation that the new engine regulations may entice the Bavarian automaker back into the series. According to Minardi, BMW's marketing division is pushing for the automaker's return to F1, with the board slated to make a decision in May. BMW would be more likely to consider an engine-supply deal rather than taking a team over like it had with Sauber, but with which team or teams it might collaborate remains a big question mark at this point.
As if that's not enough, Ford is said to be considering taking over Cosworth's aborted V6 turbo engine program to take both outfits back into the sport as well. Cosworth supplied F1 engines under the Ford banner for years, but returned under its own name for four seasons from 2010 through 2013 before shuttering its program to develop an engine to meet the new regulations adopted this season.

Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:
