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).

The 24 Hour War: Adam Carolla's new documentary brings the Ford-Ferrari battle back to life

Long before the GoPro or even videotape, races were filmed by guys standing next to the track with 16-millimeter cameras. The images kind of shook, they didn't always hold focus, and over the years all the color has faded out of the film. It all conspires to make the endurance racing battle between Ferrari and Ford in the 1960s seem like ancient history. What Adam Carolla and Nate Adams' new documentary The 24 Hour War does best is make that inter-corporate battle feel as if it happened yesterday. Yeah, if you're an obsessive you've likely seen most of the shaky-cam race footage used here before. But what you haven't seen are the interviews that frame the war and explain the egos and engineering behind the legends. It's not a perfect movie, but it's the sort of movie only fanatics could make. And it's easier to appreciate if you're a fanatic too. The first 25-or-so minutes of the documentary are taken up with histories of both Ford and Ferrari and an overview of how ridiculously deadly motorsports were in the Sixties and earlier. It's all interesting (if familiar) stuff, that could have been handled in about a third the time with some brutal editing. Still, the two protagonists in the story are well drawn: the racing-crazed Enzo Ferrari, who only builds road cars to stay solvent; and Henry Ford II, who after being thrown into the deep end of the Ford Motor Company management in 1943 at the age of 25, wasn't going to be humiliated after Ferrari pulled out of a deal to sell him the sports car maker. With one notable exception, the filmmakers were successful in rounding up practically everyone involved who is still alive for an interview. That includes Dan Gurney, Mario Andretti, Pete Brock, Bob Bondurant, Piero Ferrari, Mauro Forghieri, Carlo Tazzioli, and even Ralph Nader. There are good archival insights from the late Carroll Shelby. But where's A.J. Foyt? After all, he co-drove the stupendous Ford GT40 Mark IV with Dan Gurney to victory at Le Mans in 1967. The interviews make the movie worthwhile, but it cries out for more technical depth about the cars themselves. Yes, the GT40 was complex and engineered practically like a production car, but there's no mention of how the Lola Mk VI and Eric Broadley kicked off the development. There's only a superficial explanation of what made the American-built Mark IV such a leap forward.
