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).

Production of Shelby GT350 is coming to an end

One Autoblog staffer who drove the limited-edition Shelby GT350 wrote it probably was the best Mustang he'd driven, but, at some point, the fun had to come to an end: December 31 is the last day the GT350 will be available to order.
The GT350's option list has evolved much like it did for the original 1965-67 GT350. For 2011, the 45th Anniversary edition only came in coupe form and was painted white with blue stripes, just as with the 1965 car. The 2012 GT350 was offered as a coupe or convertible, and three colors were added to the option list, just like the 1966 model. For 2013, more colors and options were added in addition to equipment and styling updates, which resulted in Wilwood instead of Baer brakes. No major changes were made for the 2014 model. From the first car in 2011, customers have been able to choose between three different configurations for their 5.0-liter V8: naturally aspirated with 440 horsepower, supercharged with 525 hp (with warranty) or supercharged with 624 hp (without warranty).
"When we unveiled this latest version of the Shelby GT350, we promised it would be built for a limited time to preserve its collectability and value," states John Luft, president of Shelby American. He may have a point, because the original GT350, which also had a limited production run, is among the most valuable muscle cars in the world.

J Mays retiring from Ford design, succeeded by Moray Callum

Ford's highly influential head of design, J Mays, has announced that he'll be retiring from his position after 33 years in the industry, 16 of which were at the Dearborn, MI-based company. Upon departure, he'll be succeeded as group vice president of design by Moray Callum. If that last name sounds familiar, yes, he's the brother of Jaguar's Ian Callum.
It's difficult to explain just how big of a role Mays had on not just Ford's design over the years, but on the entire industry. Before heading to Dearborn, Mays worked for Audi, BMW and then Volkswagen, where he was involved in concept cars that paved the way for design icons like the first-generation Audi TT and the Volkswagen New Beetle. As for his Ford resume, it's extensive.
Mays joined the company in 1997 as design director for Ford, Lincoln, Mercury and Mazda, as well as the Premier Automotive Group (Volvo, Land Rover, Jaguar and Aston Martin). He was heavily involved in the Ford Fusion, Focus, Fiesta, Taurus, F-150 and Mustang, while also contributing to concept cars like the Atlas, Evos, 427, Forty-Nine, Shelby GR-1, Lincoln MKZ and the MKC.
