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 ain't got a care about ruining his wheels

During a drifting session at Irwindale Speedway in California, Ken Block made a boo-boo that would send a number of drivers immediately back to the infield. But there's an answer to "What do you do when you bash the wall while drifting and your wheel explodes?" and there's completely different answer when the question begins with the phrase, "When you're Ken Block..."
Instead of us telling you how Block handled the calamity in his Ford Fiesta competition car, you can watch it happen in the video below. You can probably also guess what it is - but it's more fun to watch.

These Canadians somehow forgot how to drive in snow

Montreal drivers experienced a slow-motion pileup on their streets this weeks thanks to the first snow fall of the season. According to the CBC, slippery conditions caused a small pileup involving cars, buses and even a street clearing vehicle. Onlookers in neighboring office buildings watched as vehicle after vehicle slid down Cote du Beaver Hall and crashed into the scrum of waiting cars. First there was a city bus, then a white Ford F-150 work truck loaded down with ladders, then another city bus came along and sandwiched the poor F-150. A Montreal Police Charger then came down the hill backwards, hit the bus in a slow, sad crash before it was crashed into by an out of control plow truck. Since its posting yesterday, the video of the crash has gone viral. Various other vehicles–a green-topped Scion delivery truck and a couple workaday sedans–were lucky enough to escape the pileup, but still suffered through a white-knuckled slippery descent down the hill. Colin Creado, who works nearby the crash site, told the CBC although it was pretty slippery, he was surprised at all the carnage since the storm was forecast well in advance. "You would have thought ... they would have salted the area or at least cordoned it off, because that road is pretty steep," he told the station.
