2016: The year of the autonomous-car promise

About half of the news we covered this year related in some way to The Great Autonomous Future, or at least it seemed that way. If you listen to automakers, by 2020 everyone will be driving (riding?) around in self-driving cars. But what will they look like, how will we make the transition from driven to driverless, and how will laws and infrastructure adapt? We got very few answers to those questions, and instead were handed big promises, vague timelines, and a dose of misdirection by automakers. There has been a lot of talk, but we still don't know that much about these proposed vehicles, which are at least three years off. That's half a development cycle in this industry. We generally only start to get an idea of what a company will build about two years before it goes on sale. So instead of concrete information about autonomous cars, 2016 has brought us a lot of promises, many in the form of concept cars. They have popped up from just about every automaker accompanied by the CEO's pledge to deliver a Level 4 autonomous, all-electric model (usually a crossover) in a few years. It's very easy to say that a static design study sitting on a stage will be able to drive itself while projecting a movie on the windshield, but it's another thing entirely to make good on that promise. With a few exceptions, 2016 has been stuck in the promising stage. It's a strange thing, really; automakers are famous for responding with "we don't discuss future product" whenever we ask about models or variants known to be in the pipeline, yet when it comes to self-driving electric wondermobiles, companies have been falling all over themselves to let us know that theirs is coming soon, it'll be oh so great, and, hey, that makes them a mobility company now, not just an automaker. A lot of this is posturing and marketing, showing the public, shareholders, and the rest of the industry that "we're making one, too, we swear!" It has set off a domino effect – once a few companies make the guarantee, the rest feel forced to throw out a grandiose yet vague plan for an unknown future. And indeed there are usually scant details to go along with such announcements – an imprecise mileage estimate here, or a far-off, percentage-based goal there. Instead of useful discussion of future product, we get demonstrations of test mules, announcements of big R&D budgets and new test centers they'll fund, those futuristic concept cars, and, yeah, more promises.

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).
