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).

James May picks 13 most significant cars ever for London Classic Car Show

James May tends to be the most pragmatic of the Top Gear UK hosting crew. Jeremy Clarkson obviously likes his vehicles loud, brash and preferably British, and Richard Hammond seems to have a thing for American muscle. May appears to find joy just in the mechanical nature of things, whether high performance or simply made for getting around. He's getting a chance to put that appreciation on display by curating a 13-car collection at the London Classic Car Show called The Cars That Changed The World. May actually wants to provoke debate from visitors about the exhibit and is separating his choices into two categories: The Halls of Obviousness and The Chambers of Bloody-mindedness. The first bunch includes the usual important vehicles you expect to see, but the other group has the really interesting picks. As May explains these selections in the event announcement, "I believe they are just as significant historically but they've simply been forgotten or misunderstood." The obvious choices are: 1886 Benz Motorwagen 1908 Ford Model T 1938 Volkswagen Beetle 1959 Austin Mini 1964 Ford Mustang 1997 Toyota Prius And the more eccentric ones are: 1901 Waverley Electric 1906 Cadillac Model K 1933 Standard Superior 1972 Honda Civic 1980 Lada Riva 2009 Bruno ExoMars Rover If you notice, there are only 12 vehicles listed above. That's because the final one is being kept secret for show attendees, but May considers it the most significant car ever made. The London Classic Car Show runs at the ExCeL in London's Docklands from January 8-11, 2015. In addition to May's exhibit and the other vehicles there, Formula 1 designer Adrian Newey is also curating a display from his own collection. May is hoping to spur conversations with his choices. Let us know in Comments if you notice any glaring omissions that should be among the 13. Read the full announcement below, along with a brief explanation for each choice from May. GET READY FOR A CLASSIC ARGUMENT 30/12/14 James May has chosen the 13 most significant cars of all time for The London Classic Car Show... but is he right? It's bold, controversial and bound to cause arguments... and that's just the way BBC Top Gear's James May wants it. May has stuck his neck on the line and has chosen what he regards are the 13 most influential cars of all time. The result is The Cars That Changed The World and it's one of the star exhibits at the London Classic Car Show taking place at ExCeL in London's Docklands from 8-11 January 2015.
