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).

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.

Ford recalls 382k vehicles across six campaigns

Ford needs to repair a total of 381,633 vehicles in North America across six newly announced campaigns, including five safety recalls and one compliance recall. By far the largest of these campaigns covers the 342,271 examples of the 1998-2003 Windstar to double check an earlier recall repair. Among these, 283,413 are in the US and 58,858 are in Canada. The combination of corrosion and stress can cause cracks in the rear axle and eventually lead to the part to snap completely. The company reports a small number of accidents might be connected to this, but there are no injuries. The minivans were recalled for this issue back in 2010, and it was investigated by NHTSA. According to Ford's latest announcement, the reinforcement brackets on some of these models might not have been installed correctly. This time, dealers will perform an inspection. Minivans with incorrectly installed brackets will get a new rear axle. The rest of the owners will be offered a deal to replace the part at a reduced cost. The next largest campaign covers 36,857 examples of the 2015 F-150 to fix a problem with the adaptive cruise control. Specifically, there are 33,481 affected trucks in the US, and 3,376 in Canada. According to Ford, "when passing a large, highly reflective truck" the radar in the system can misidentify a semi as being in the same lane as the pickup. The collision warning system would then activate, slowing the F-150. There's one report of an accident with this happening but no injuries. The fix is simply an update to the adaptive cruise control module software. Ford also has a recall for 1,477 examples of its 2016 F-53 and F-59 stripped chassis models, and they're all located in the US. A manufacturing issue might allow the trucks to shift into reverse without the driver first applying the brakes. There are no reports of any accidents from this, though. To repair the problem, the models get a new transmission shift control bracket and an adjustment to the shift cable. The Blue Oval's safety compliance recall covers 708 examples of the 2016 Fusion and Lincoln MKZ, including 658 of them in the US, 28 in Canada, and 22 in Mexico. On these models, a manufacturing problem with the fuel tank could allow it to crack in a crash, which isn't allowed under federal rules. There are no reports of accidents, injuries or fires. The fix will be a new fuel tank for all of them. The company is also repairing 251 units of the 2015 Taurus and Lincoln MKS, plus the 2016 Explorer.
