NHTSA releases updated Takata airbag recalled cars list, but it still has errors

Unfortunately, the government's list still contains errors.
The National Highway Traffic Safety Administration has issued an updated list of vehicle models that it's urging owners to repair under the mushrooming Takata airbag inflator recall. The latest version adds vehicles from new automakers like Subaru and Ford that are missing from the original announcement, and it also removes erroneous entries from General Motors, leaving only the 2005 Saab 9-2X (a reskinned Subaru WRX), and the 2003-2005 Pontiac Vibe, a joint project with Toyota.

2015 Ford Mustang prototype spotted on the street

Our trusty spy photographers have snapped the first photos of the 2015 Ford Mustang prototype out on public streets. With nearly every square inch of the machine covered in heavy camouflage, it's difficult to discern details, but we can see smallish horizontal headlamps at work in the coupe's nose. Ford has made it clear that modern lighting technology will allow the company to get away from large, expensive headlamp arrays in the near future, and the 2015 Mustang may very well be the first of the automaker's products to bow with the new tech. The philosophy was first displayed on the very attractive Evos Concept.
The extensive cladding doesn't extend all the way to the prototype's rockers in the instance, giving us a look at the heavily-sculpted sills. Overall, this test car looks considerably smaller than the current generation Mustang, and elements like a short front overhang and beefy dual-piston calipers give us plenty of hope for the future model. Of course, reports that the 2015 Mustang will bow with an independent rear suspension and EcoBoost power certainly don't hurt our feelings, either.

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).
