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 recalls 434k vehicles for several unrelated issues

It seems that the hard winter in much of the country has been as rough on some Fords as it has on many people. The Blue Oval is recalling roughly 434,000 vehicles in two separate recalls, and one of them partially caused by the salt used to melt the snow on roads.
The first recall covers 385,750 2001-2004 Escape models in the Midwest, Northeast and Canada because a subframe could rust and eventually fail. This is partially due to the road salt used in those areas, and about 349,000 of the affected vehicles are in the US. To remedy the problem, dealers are installing a reinforcement cross brace on the frame to strengthen them. There has been one crash caused by the failure but no injuries. According to The Detroit News, this is not the first rust-related recall for Ford. It estimates the company has repaired over two million vehicles since 2010 for problems on vehicles related to the iron oxide, including the rear wheel wells of the Freestar minivan.
The second recall covers 48,950 2013-2014 Ford Fusion, Escape, C-MAX and Lincoln MKZ models because welds in their seatbacks don't meet National Highway Traffic Safety Administration standards. The fault affects the front seats, and the sub-standard welds joining the setback to the recliner could increase the chance on injury. There have been no reported injuries or accidents caused by the problem, but there are 42,972 affected vehicles in the US and 4,744 in Canada.

Ford bringing adaptive steering to the masses [w/video]

Within the next year, Ford will offer a brand-new adaptive steering system (unimaginatively dubbed "Ford Adaptive Steering"), and this week, the automaker invited us out to its proving grounds in Dearborn, MI to get a taste for how its new setup works. In function, Ford's system doesn't greatly differ from the majority of other adaptive steering units already on the market from companies like Audi or BMW, but consider this: Ford will be the first non-luxury automaker to offer this technology, and uniquely, the whole system fits inside the car's steering wheel.
Ford's engineers have worked hard to create a system that can be tacked on to the company's full lineup of cars, trucks and utility vehicles, and says that the adaptive steering will be uniquely tuned for each specific vehicle. The automaker will not confirm exactly which vehicle will launch with this technology, but for the purpose of our preview, we tested the technology in a 2014 Fusion - a vehicle with already-good behind-the-wheel feel, one that the company says best demonstrates its current steering efforts.
