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 to revisit CVTs?

Today, Ford wishes its first experience with non-hybrid continuously variable transmissions was far behind it. The Blue Oval was awash in complaints and a couple of class-action lawsuits over the CVTs used in its 2005-2007 Ford Freestyle, Five Hundred and Mercury Montego models, which were a manufactured in Batavia, Ohio as part of a joint venture with ZF. The company gave up on the CVT after just two years, but with fuel economy standards pressing automakers to conjure new tricks, Ford's global product development head, Raj Nair, is now saying the transmissions might make a return, "particularly in the low torque applications," says Automotive News. An obvious candidate for CVT consideration is the 1.0-liter Fiesta that can presently only be had with a five-speed manual. Beyond that, the company's 1.6-liter and 2.0-liter four-cylinder engines might fit the bill. Ford hasn't given any indication as to what vehicles it might use to reintroduce the CVT to the US market, or hints about timeline or who would develop it, however. Some CVT trivia: The 1990 Subaru Justy II was the first US passenger car offered with a continuously variable transmission - Subaru called it the ECVT. It handled gearing duties for a 1.2-liter, inline three-cylinder engine that got all of 70 horsepower. A contemporary blurb about the car begins with "Goodness, gracious, great gobs of gimmickry," and goes on to say that "We can't imagine where you would take this car for repairs, but we are certain that the one mechanic in the world who can fix it lives in a very expensive house." The transmission didn't win any fans, but the ECVT and the car have been largely forgotten, while Subaru played the long game and now you'll find its vastly improved Lineartronic CVT on six of the eight models it sells.
