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).

Ken Block is at it again in Gymkhana 6

If there's one thing we'll say about Ken Block and his latest installment in the Gymkhana family, it's that it's far more structured than previous videos, but that doesn't mean it skimps on the entertainment. Block is on a purpose-built course which was touted as "The... Ultimate... Gymkhana... Grid... Course" in last week's preview. Unlike Gymkhana 5, which took placed on closed streets in San Francisco, this course seems much more compact.
Block has an entire array of challenges to tackle in his 650-horsepower Ford Fiesta ST, and none of them look particularly easy. In fact, we'd argue that Gymkhana 6's grid course requires much more precise driving that previous titles. There are Segways, Lamborghinis and massive pieces of construction equipment that all must be dealt with.
We've got the entire 6:28 of Gymkhana madness for you down below. Scroll down for the video and then hit Comments and let us know how this installment compares to previous Block works.

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.
