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 going bonkers at SEMA with 57 showcars

Ford always shows up in force at the SEMA Show, but this year's tally of 57 custom-tuned cars, trucks and vans is more than we can ever recall the Blue Oval bringing. Ford will introduce 28 of its project vehicles in its "Dreamcase" ahead of next month's show. The first batch of eight you'll find here with the remaining vehicles trickling into public view over the next couple of weeks.
This first group of cars includes a Fiesta, four Fiesta ST hatchbacks and a trio of Mustang show cars styled and tuned to varying degrees all by different aftermarket companies. Tanner Foust, Nitto Tire, 3dCarbon and Ice Nine Group are some of the more familiar names affixed to these cars. Our favorite so far is the Hollywood Hot Rods Mustang convertible (shown above) with its removable aluminum top and methanol-injected, 750-horsepower 5.0-liter V8.
Scroll down for all the details on these Fiestas and Mustangs, and stay tuned for more info on Ford's SEMA line, which will include custom versions of the Focus ST, Fusion, Transit Connect, F-150 and Super Duty.

Cheap gas has Ford investors nervous over 2015 F-150

Gasoline in the US continues its weeks-long descent with prices down about 13 cents a gallon over last week to $2.544, which is lower by around 69 cents/gallon from this time last year, according to the US Energy Information Administration. Many drivers are welcoming the lower bills at the gas station as a fantastic holiday gift, but Ford investors are somewhat spooked over the potential sales implications for the 2015 F-150. Market analyst Rod Lache of Deutsche Bank recently downgraded Ford's stock from a buy to hold, according to TheDetroitBureau.com, and his report to investors may have played a part in a drop in the company's share price. Lache praised the truck's powertrain and lightweight technology, but wrote, "We question whether consumers will pay the price for this content with $2-$3 gas," in his report, according to the website. Whether buyers actually turn away from the F-150 is mostly speculative at this point because it only recently began production. With around 700 pounds of weight loss thanks in parts to its new aluminum parts, the latest Ford pickup offers up to 26 miles per gallon on the highway, plus segment-best payload and towing ratings. Prices are up somewhat in part to pay for additional standard features, though. Still, any further dip in Ford's stock is bad news this year. According to TheDetroitBureau.com, the company's shares are down about 7.5 percent this year. On December 15, the price fell to $14.28, the lowest since November 10. Related Video:
