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).

2015 Ford F-150 [w/videos]

To learn more about the all-new 2015 F-150 and get an early read on its potential hero-or-zero status, we flew to the heart of full-size pickup truck country, San Antonio, TX, to spend a day driving, towing and playing in the mud with an assortment of Ford's innovative new trucks.
First, a caveat - while we feel we have a reasonably good handle on the new F-150 after attending this first-drive event, we are far from ready to pass definitive judgment on the success of this radically new rig. Our time in the various models was lamentably limited and we felt rushed. With so much at stake and with so much to talk about and experience, we had zero alone time with the vehicle - there were Ford folks shadowing us at every moment.
And we still don't know everything there is to know about the trucks, as Ford is withholding some of its most crucial numbers, including curb weight data and anticipated EPA fuel economy figures. We don't even have a firm on-sale date. All of this information is typically disclosed - or at least officially estimated - at the time of a new vehicle's first drive. This limits the scope of the judgments we feel comfortable making based on our first encounter.

2016 Ford Focus RS to start at $35,730? [UPDATE]

UPDATE: Unsurprisingly, Ford declined to comment on the pricing shown on the consumer page, with spokesman Aaron Miller telling Autoblog that the Blue Oval does "not comment on pricing speculation." The webpage showing the $35,730 figure has since been pulled down. We love it when automakers make little, tiny mistakes. You know, not the big stuff that leads to recalls, but the small things, like accidentally releasing pricing of a hotly anticipated model via its US consumer website. Such a thing has apparently happened to Ford, as Jalopnik's Car Buying sub-blog has uncovered a page on the site listing the starting price of the 2016 Focus RS. The cost of entry for the 345-horsepower, all-wheel-drive, torque-vectoring hot hatchback is $35,730, according to the website. That's $1,035 more than the base Subaru WRX STI, although it's $865 less than the Volkswagen Golf R. Considering the RS outguns both models by a very significant margin – 40 horsepower over the STI and 47 over the Golf R – that price seems very agreeable. If it's correct, that is. Aside from showing the RS' starting price, the page also gives us a glimpse into the options sheet. There's an RS2 equipment level that adds $2,795 to the base price along with navigation and leather Recaro seats, an $895 sunroof, and a 19-inch wheel and Michelin Pilot Sport Cup tire package for $1,990 (or just $1,395 for the 19s alone). Some fiddling with the quite incomplete configurator – there are no images and the overall design is rather glitchy – revealed a max price of $42,275. We've reached out to Ford for confirmation of the pricing information displayed. Head into Comments and let us know what you think of the pricing. Has Ford hit it out of the park by slotting in a more powerful competitor between the Subaru and Volkswagen? Were you expecting a higher price (like your author), or is this still too much money for a jumped-up Focus? Related Video:
