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).

Second-tier UAW workers promoted for first time after Ford hits quota

The United Auto Workers put out a statement on Friday that 55 Ford workers chosen by seniority would be moved from the Tier 2, entry-level pay rate of around $19 per hour to the Tier 1, non-entry-level rate of about $28 per hour. One of the stipulations in the 2011 UAW-Ford agreement was that only 20-percent of the total hourly workforce could be paid the Tier 2 wages agreed upon in 2007; after that, those workers had to be moved to Tier 1. Even so, the new Tier 1 status makes them less expensive to Ford than veteran Tier 1 workers because they receive fewer benefits. However, Automotive News had reported that same day that Ford was 69 workers shy of the limit, and when AN asked Ford about the situation Ford said it had "some room" on the entry-level roster. If workers do move to the higher pay grade, it will be the first time that's happened since the two-tier system was agreed. But it sounds like there's going to be some haggling between the UAW and Ford before that happens. Ford is the only one of the Detroit 3 automakers to have to work with a cap, since it didn't go through bankruptcy proceedings during The Great Recession; General Motors and Chrysler jettisoned the cap in 2009. GM is said to have 16 percent of its hourly workers at Tier 2 while Chrysler has 42 percent, but Fiat-Chrysler CEO Sergio Marchionne has long been opposed to the two-wage system. The UAW is preparing for its 2015 negotiations with the US automakers. It wants to eliminate the difference in pay by going to the higher scale, if there is a consensus among automakers it seems to be that they also want a single wage, but less than the higher scale, with the addition of profit-based bonuses. The recent statement from the labor union is below. UAW President Dennis Williams and UAW-Ford Vice President Jimmy Settles announced today that the union is delivering on its promise to convert workers DETROIT, Jan. 30, 2015 /PRNewswire/ -- UAW President Dennis Williams and UAW-Ford Vice President Jimmy Settles announced today that the union is delivering on its promise to convert workers making entry-level wages to traditional employees. "The 2011 UAW-Ford agreement allows for a contractual limit of entry-level employees. Once that threshold is surpassed, entry-level employees convert by seniority to 'regular, non-entry level employment.' At this time, fifty-five UAW-Ford workers will receive the wage increases, which put them in the category of non entry-level employment.

Ken Block is at it again in Gymkhana 6

If there's one thing we'll say about Ken Block and his latest installment in the Gymkhana family, it's that it's far more structured than previous videos, but that doesn't mean it skimps on the entertainment. Block is on a purpose-built course which was touted as "The... Ultimate... Gymkhana... Grid... Course" in last week's preview. Unlike Gymkhana 5, which took placed on closed streets in San Francisco, this course seems much more compact.
Block has an entire array of challenges to tackle in his 650-horsepower Ford Fiesta ST, and none of them look particularly easy. In fact, we'd argue that Gymkhana 6's grid course requires much more precise driving that previous titles. There are Segways, Lamborghinis and massive pieces of construction equipment that all must be dealt with.
We've got the entire 6:28 of Gymkhana madness for you down below. Scroll down for the video and then hit Comments and let us know how this installment compares to previous Block works.
