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).

What an Atlas-based Ford F-150 might look like

Just ahead of January's Detroit Auto Show, surprising rumors pegged Ford as revealing some sort of F-150 concept, perhaps as a hurried effort to deflate some of the buzz building around General Motors' new Chevrolet Silverado and GMC Sierra twins, which were also making their auto show debut. Those rumblings turned out to be true, as Ford rolled into the Motor City with its Atlas concept (inset, right), touting the truck's bold styling as a precursor to the next-generation F-Series.
The show truck featured all kinds of clever details, including active wheel shutters and a front air dam that raised and lowered to improve aerodynamics while preserving off-road ability. It also had a genuinely snarly face. And it's that pugnacious snout that may well be on its way to production. The good folks at TopSpeed have worked up the plausible-looking artist's rendering above by cross-referencing the Atlas concept with what little has been revealed from recent spy shots. The look is toned-down pretty dramatically from the concept truck, but its Atlas roots are clear, with a massive three-bar grille and bracket-shaped headlamps hiding a next-generation EcoBoost engine. In the rendering, the show truck's deeply contoured hood and roofline have been ditched and larger, more traditional side mirrors have been fitted - all likely concessions in the move to production sheetmetal.
While Ford has yet to officially announce when it will unveil the 2015 F-150, all signs point to next year's Detroit Auto Show - one year after the Atlas shrugged off GM's new pickups.

Takata air bag recall list

The National Highway Traffic Safety Administration confirmed yesterday that 33.8 million vehicles with Takata airbags are going to be recalled. It's the largest recall in automotive history. The already record-breaking rate of automotive recalls this year shows no signs of slowing down, especially since millions of cars with defective airbags made by global supplier Takata are under ongoing scrutiny. The federal government is warning owners that inflator mechanisms in the air bags can rupture, causing metal fragments to fly out when the bags are deployed. The faulty air bags have already been blamed for multiple deaths. How do you know if your vehicle is safe? The National Highway Traffic Safety Administration released an updated list of vehicles under recall. Sometimes however, the government's website will crash and the list may not be complete. Check your VIN at the NHTSA website to make sure. The list of cars affected by the recall has not been released, but seem to span multiple models over the years for many of the automakers.
