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 126,000 Fusions and Milans over wheel separation concern

Ford has announced a recall of certain Ford Fusion and Mercury Milan vehicles after an investigation by the National Highway Traffic Safety Administration. A total of 128,616 2010 and 2011 models equipped with steel wheels may have been manufactured with wheel studs that could crack and split over time. If that happens, the vehicle may experience a wheel separation.
According to The Detroit News, the company is aware of a total of 30 wheel separation incidents, one of which occurred on the front of the vehicle. Even so, no injuries have been reported as a result of the defect.
The problem apparently stems from the fact that the mounting pads on the vehicles' steel wheels may have been faulty from the factory. In addition, the wheel mounting face on rear disc brakes may not have been installed properly. Ford will inspect the rear disc face and replace them as necessary. In addition, the company will replace all of the vehicle's wheel studs free of charge. Head to the NHTSA website for more information, and click past the jump to view the full recall notice.

Next Lincoln Navigator to drop V8 in favor of V6, but Ford Expedition might get both

A great many buyers fled from full-size body-on-frame SUVs to car-based crossovers in large measure to save fuel. But that doesn't mean there's still not a buying audience for more traditional truck-based utility vehicles, and those consumers doubtlessly wouldn't mind saving some dollars at the pump, too. According to Motor Trend, those shoppers might be in luck.
That's because the magazine has confirmed that Ford isn't walking away from the full-size SUV segment, and it's poised to do something about its offerings' economy ratings, too. According to MT, global Lincoln director Matt VanDyke has hinted that the next Navigator may drop two cylinders and go with a V6 model - the current model gets just 14 miles per gallon in the city and 20 on the highway from its 5.4-liter V8. The obvious fitment would be Ford's 3.5-liter twin-turbo EcoBoost V6, an engine that has spread like kudzu throughout the rest of the Blue Oval's large vehicle lineup.
Downsized turbocharged engines like Ford's EcoBoost franchise have come under fire as of late for not delivering their EPA fuel economy ratings, but their benefits extend beyond consumption - the 3.5L offers superior power and a better torque curve than the naturally aspirated V8. MT also suggests that Ford's 3.7-liter V6 could form the base engine for the next Navi - it has similar horsepower but a lot less torque than the current 5.4L. That may be less of a problem with the next generation tipped to go on a diet, which could level the playing field somewhat.
