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).

Scandal-rocked UAW extends Ford, FCA contracts, prepares to strike GM

DETROIT — Leaders of the United Auto Workers union have extended contracts with Ford and Fiat Chrysler indefinitely, but the pact with General Motors is still set to expire Saturday night. The move puts added pressure on bargainers for both sides as they approach the contract deadline and the union starts to make preparations for a strike. The contract extension was confirmed Friday by UAW spokesman Brian Rothenberg, who declined further comment on the talks. The union has picked GM as the target company, meaning it is the focus of bargaining and would be the first company to face a walkout. GMÂ’s contract with the union is scheduled to expire at 11:59 p.m. Saturday. ItÂ’s possible that the four-year GM contract also could be extended or a deal could be reached, but itÂ’s more likely that 49,200 UAW members could walk out of GM plants as early as Sunday because union and company demands are so far apart. Picket line schedules already have been posted near the entrance to one local UAW office in Detroit. Art Wheaton, an auto industry expert at the Worker Institute at Cornell University, expects the GM contract to be extended for a time, but he says the gulf between both sides is wide. “GM is looking through the windshield ahead, and it looks like nothing but land mines,” he said of a possible recession, trade disputes and the expense of developing electric and autonomous vehicles. “I think thereÂ’s really going to be a big problem down the road in matching the expectations of the union and the willingness of General Motors to be able to give the membership what it wants.” Plant-level union leaders from all over the country will be in Detroit on Sunday to talk about the next steps, and after that, the union likely will make an announcement. But leaders are likely to face questions about an expanding federal corruption probe that snared a top official on Thursday. Vance Pearson, head of a regional office based near St. Louis, was charged with corruption in an alleged scheme to embezzle union money and spend cash on premium booze, golf clubs, cigars and swanky stays in California. ItÂ’s the same region that UAW President Gary Jones led before taking the unionÂ’s top office last year. Jones and other union executives met privately at a hotel at Detroit Metropolitan Airport on Friday. After the meeting broke up, JonesÂ’ driver and others physically blocked an AP reporter from trying to approach him to ask questions.

What car should James Robertson buy to drive his famous 21-mile commute?

The Internet has been abuzz this week with the story of Detroit resident James Robertson, the 56-year-old factory worker who has walked some 21 miles to work for the last 10 years. The Detroit Free Press brought Robertson's story to the fore, helping an online fundraising campaign to generate more than $275,000 (as of this writing). The original goal was just $5,000, or about enough to replace the used Honda that died on Robertson back in 2005, and left him walking. So, newly flush with funds, what's the perfect car for Robertson to buy? Let's look at the specifics of his situation, and try to pick out the best options. Here's what we know: Robertson's commute is (famously) 21 miles; he lives in downtown Detroit (for now) and seems pretty humble, so something very flashy is probably out; former Honda aside, his ties to the city (and statements about being a Ford fan) seem to indicate a Detroit Three company product is best; he's a single guy with a girlfriend; he's got to deal with Michigan weather, and the sometimes fickle snow removal processes in The D. Here are some choices: Ford F-150 Robertson is on record as being a Taurus fan, and after a decade of walking I've no doubt that the big sedan would offer a cozy respite. Still, as a car guy and a student of the industry, I'd have a hard time recommending a sedan so clearly in need of replacement. Especially when The Blue Oval has such great stuff within the rest of its roster. The 2015 F-150 seems almost perfect for Robertson. Opting for either of the new EcoBoost V6 engines should help keep fuel bills in reasonable check, while healthy ride height and four-wheel drive will get him to work on time even during the snowiest of snow days. Better still, with a fat options sheet and car-like ride quality, Robertson can have just about every amenity he might want, in a package that won't disrespect his blue-collar roots. Chevrolet Colorado You guys saw this one coming, right? The smaller footprint of the midsize Chevy pickup, relative to some of the other options here, should be an advantage for urban parking and driving. And again, 4x4 is an option for the nasty weather, the running costs should stay pretty low and there aren't many tech/luxury features that can't be had in-cabin. I'd go ahead and splash out on the Crew Cab bodystyle, too, just in case Robertson feels like starting a carpool.
