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 pulls official support from top-level NHRA teams

As the smallest team in the sport, it wasn't really a surprise when Dodge decided to pull out of NASCAR, but Autoweek is reporting that Ford is looking to pull the plug on its professional-level NHRA sponsorships following the 2014 season. With attendance and television ratings down, the article reports that Ford is just backing out of the top series but will remain active in the Sportsman classes of racing, which are geared more toward the grassroots and semi-professional racers.
This means that one of drag racing's biggest names, John Force, will be left looking for new sponsorship after next season. Force, 64, has been with Ford for 17 years, winning 15 championships in that time and winning almost half of all Funny Car events in his Mustang since he started working with Ford in 1997, but after 2014, there could be some big shakeups at John Force Racing.
According to the report, Force would consider is moving over to the Top Fuel dragster series, although he could also move to another manufacturer to remain in the Funny Car series. With Ford on the way out, this leaves just Toyota and Dodge as the remaining active automakers in the highest levels of drag racing.

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.
