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).

Muscle wins big at 2013 Amelia Island Concours as 1936 Duesenberg, 1968 Ford GT40 take top honors

The 18th-annual Amelia Island Concours d'Elegance took place this past weekend, and in one of the show's biggest years yet (bringing in more than 25,000 spectators and attracting more than 300 vehicles), two powerhouses ended up winning the judges' hearts. The top Concours d'Elegance award went to a 1936 Duesenberg SJN, while the Concours de Sport went to one of the celebrated marques, a 1968 Ford GT40.
Owned by Helen and Jack Nethercutt of Sylmar, CA, this flawless Duesy is described as "one of the most powerful open cars of the 1930s," and it displays design cues of the era like rolled fenders and a tapered rear end. The SJN's supercharged straight-eight allowed it to accelerate to 100 miles per hour in just 17 seconds - surely not a disappointing feat for its day.
On a much different level of performance and timelessness, this Gulf-livery GT40 from the Rocky Mountain Auto Collection is not outdone by the elegance of the big Duesenberg thanks to some well-documented racing history. This not only includes winning at LeMans in both 1968 and 1969 - Chassis No. 1075 also managed to win a total of six times in just 11 races.

NHTSA investigating Ford's solution to May 2014 power steering recall

The National Highway Traffic Safety Administration is investigating a complaint that Ford's response to a May 2014 recall of the 2008 to 2011 Ford Escape and Mercury Mariner doesn't quite go far enough to solve a troubling power-steering problem. Roughly a year ago, Ford recalled nearly a million vehicles after it was found that a problem with the torque sensor's communication with the power steering control module could cut steering assistance for drivers. While manual steering would still be available, the problem was enough to ask drivers to report in to have the PSCM inspected, and if necessary, replaced (along with the torque sensor, or in dramatic cases, the entire steering column). That would only happen, though, if trouble codes were being thrown. If there weren't any problems, dealers were told to simply update the PSCM's software so that any issues between it and the torque sensor would simply throw a visual and audio warning – power steering would still be maintained. The petitioner claimed that following the recall work, he still experienced a problem with the torque sensor. According to NHTSA, a claim was made that Ford didn't go far enough in its solution to the problem, and that "the software update itself may in fact cause further issues with the affected vehicle's power steering, causing it to fail, and ultimately requiring replacement of the torque sensor or entire steering column." The petition was filed in early February and is now officially being looked into by NHTSA.
