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 recalling select Taurus, Explorer and Lincoln MKS models over fuel tanks

Ford is recalling certain 2012 Taurus, 2013 Explorer and 2012 Lincoln MKS models over fuel tank concerns. According to the National Highway Traffic Safety Administration, vehicles built between July 19, 2011 and March 15, 2012 may have been built with fuel tanks that have a "marginally sealed seam" on the side. Those seams may not provide the strength necessary to protect the tank from rupture during a collision. They may also leak. The recall covers a total of 3,037 vehicles. NHTSA says that leaked fuel, in the presence of an ignition source, could easily cause a fire.
Dealers will inspect the tanks and replace them as need be free of charge. Owners can expect to be notified once the campaign begins on or around April 22, 2013. You can read the full NHTSA recall notice below for more information.

Ford adds 850 jobs to build 2015 F-150

Pickup trucks tend not to advance at quite the same pace as the rest of the industry. That's what makes the new Ford F-150 so remarkable, jettisoning its old steel construction in favor of aluminum. It's a game changer that Ford is betting big on, and in anticipation of surging demand, the Blue Oval automaker is adding 850 new jobs to put the thing together.
Those 850 new employees will be centered at Ford's Rouge complex in Michigan - with 300 at Dearborn Stamping, 50 more at Dearborn Diversified and 500 at the Dearborn Truck facility, the latter of which has already kicked off what Ford describes as "the largest manufacturing transformation in decades." Old manufacturing equipment is being replaced with the latest technologies, and even the Ford Rouge Factory Tour is undergoing a complete overhaul.
The new jobs come as part of the commitments Ford made to the UAW in 2011 to create 12,000 hourly jobs in the United States by 2015 - a number which Ford has already exceeded at 14,000. Over 4,000 of those are centered in southeastern Michigan.
