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).

Help make Lego Icon Bronco a reality [UPDATE]

The Lego Ideas process is a pretty neat concept. The website allows anyone to propose a future kit, and if the project gathers 10,000 supporters within a certain amount of time, then the company investigates building it. The creator even gets a cut of the sales. We saw the operation at work last year with a very cool looking Corvette kit that hasn't hit the next stage quite yet. Now, another creator going by the username Legohero1966 has a fantastic looking replica of the Icon 4X4 Bronco hoping for support. The maker nails the boxy, brawny look of the Icon take on the classic Ford Bronco, and the Lego kit even gets the color pretty close. The miniature SUV also features a visible suspension, a removable top and, according to the description, a reel for the winch is hidden in the bumper. Underneath the body, this model even does a pretty good job of replicating the powertrain. As is expected by these kits, the hood, doors and hatch all open; on this one the spare tire carrier even moves out of the way, too. As of this writing, the Icon Bronco kit only has a little over 400 supporters, and that's a long way from the goal. If you like what you see, give the proposal a closer look on Lego Ideas. UPDATE: The original creator of the Icon Bronco kit, Paul Kim, has advised Autoblog that this Lego Ideas proposal was created without his consent, and he has reported the problem there. You can view more pictures of the Bronco and more of Kim's work, here.

Ken Block's Gymkhana 8 to feature Dubai Police cars?

Yesterday we showed you the shiny Ford Fiesta that Ken Block will slide, spin, and hoon through the next Gymkhana video. In case the image above isn't clear, that video will drop at midnight EST on February 30th on the Ford Performance YouTube channel. We don't know all the entire premise of the video yet, but this Tweet from the man himself reveals that the video will be set in Dubai. Block is standing on the Fiesta we saw yesterday, and arrayed behind him are a handful of those famous Dubai Police cars you're probably familiar with. The force has a fleet of sportscars and supercars, and the purpose is outreach and goodwill among its citizenry, not necessarily the pursuit of criminals. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. From left to right, we can see a Maserati GranTurismo, Porsche 911, what looks to be a Nissan GT-R obscured by Block's Fiesta, a McLaren (likely a 650S), Ford Mustang, and a Ferrari 599 of some ilk. Will they take part? Maybe Block will try and run from what might be the most horsepower-intensive police fleet in the world. We'll have answers (and a few minutes of pure Block hooniganism) in a few days. Related Video:
