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 F-150, Chevy Silverado, Toyota Tundra flunk IIHS headlight test

The Insurance Institute for Highway Safety put pickup truck headlights to the test and found that the majority of them were equipped with subpar units. The 2017 Honda Ridgeline was the only truck to earn a rating of "good." The large pickup truck test was comprised of the: 2016 to 2017 GMC Sierra, 2017 Nissan Titan, 2016 Ram 1500, 2016 to 2017 Chevrolet Silverado, 2016 to 2017 Ford F-150, and 2016 to 2017 Toyota Tundra. The Sierra's headlights earned a rating of "acceptable," the headlights found on the Titan and Ram 1500 were found to be "marginal," and the ones on the Silverado, F-150, and Tundra were rated as "poor." IIHS claims the F-150 was the most disappointing out of the large pickup trucks as both its halogen and optional LED headlights failed to provide adequate visibility during testing. The Ridgeline (which earned a "good rating"), is usually considered a midsize or small truck, though IIHS included it in the field of large pickups. The headlights on the 2016 Chevrolet Colorado, 2016 GMC Canyon, 2016 Nissan Frontier, and 2016 to 2017 Toyota Tacoma, which made up the small pickup truck group, all earned a rating of "poor." The IIHS claimed the Colorado had the worst headlights of any truck that was tested, as the base vehicle's units were only able to illuminate up to 123 feet in front of the car. The Ridgeline's headlights, for reference, were able to illuminate up to 358 feet in front of the vehicle. To conduct its test, the IIHS utilizes a special tool to measure how far light is projected out of the headlights in different driving situations. The trucks' headlights were tested in a straight line and in corners, while vehicles with high-beam assist were given extra praise. The headlights on the pickup trucks also mimic the testing that was done on small SUVs and cars earlier this year. Next year, automakers will need to fit their vehicles with headlights that earn a rating of either good or acceptable to earn the IIHS Top Safety Pick+. Related Video:
