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.

Feds Probe Power Steering In 938,000 Ford Midsize Cars

U.S. safety regulators are investigating complaints that the power-assisted steering can suddenly fail on three Ford midsize car models. The probe covers 938,000 Ford Fusion and Lincoln MKZ cars from the 2010 through 2012 model years, as well as the 2010 and 2011 Mercury Milan. The National Highway Traffic Safety Administration says it has received 508 complaints alleging that the cars lost power-assisted steering, causing increased steering effort. Four complaints say the problem caused crashes, but no injuries were reported. The agency says in documents posted Monday on its website that in many cases, a warning message appeared as the failure happened. Restarting the car corrected the problem in some cases, but the problem returned in others. The agency says it will check the scope and frequency of a problem. It could seek a recall. Ford says it's cooperating with the probe. Shares of Ford Motor Co. rose 6 cents to $14.65 in morning trading Monday. Its shares are down 14 percent over the past year.
