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).

Formula Drift kicks off 11th season on Streets of Long Beach

The 2014 Formula Drift series kicked off last weekend in Long Beach, and saw Chris Forsberg, who you'll recall went mad and drifted around a warehouse in an Infiniti M, take the title behind the wheel of his Hankook Tire Nissan 370Z (shown above).
Forsberg really ran away with the first round of competition, outscoring his closest opponent, second-place finisher Kenneth Moen and his Bridges Racing Nissan 240SX, by 20 points. Third place was 2013 championship winner Michael Essa and his Yokohama BMW M3, 30.5 points behind Forsberg.
In the manufacturers' title, Nissan took an early lead with 122 points, which isn't a huge surprise considering five of the top ten drifters were piloting either a Z or a product of the brand's S platform. Ford, which had two drivers (Justin Pawlak and Vaughn Gittin, Jr.) in the top ten, took home second place, while BMW is currently third in the manufacturers' standings.

How new car shortages may impact your buying experience

If you want further proof that the auto industry is bouncing back, look no further than the empty lots and forecourts of your local dealership. According to a story by The Wall Street Journal, continued high demand for mainstream cars is overtaxing automakers' ability to produce enough models. Several dealers interviewed for the story are reporting two-week supplies as opposed to the typical two-month allocations.
With sales expected to hit 1.4 million units when August numbers arrive shortly and incentive spending down to its lowest amount since January, these limited supplies are pushing prices even higher. For example, according to the WSJ, the average price of a Ford Fusion is up past $26,000. Unfortunately, it's difficult for manufacturers to increase production quickly. If it invests in its facilities, as many manufacturers have done, it risks wasting cash if growth suddenly slows. At the same time, the momentum gained over the past several years could be short lived if vehicle supplies continue to dwindle. "Manufacturers are in a precarious situation," notes Karl Brauer, a senior director at Kelley Blue Book.
Low interest rates and a wealth of desirable features are also allowing customers to purchase more expensive vehicles while justifying their higher overall price tags, a situation that is compounding supply shortages. Even now, during the annual end-of-summer clearance season, deals on new vehicles are remarkably difficult to come by. According to the report, the Toyota Corolla is in a self-inflicted state of shortage, as Toyota clears out inventory in anticipation of the new 2014 generation arriving in dealers. Ford's supplies should rebound as Fusion production comes on line at its Flat Rock, Michigan factory. The Chevrolet Impala, Honda Odyssey, Civic, and Accord and Subaru Forester are also facing shortages.
