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).

Ford C-Max spied with fresh updates

The Ford C-Max hatchback looks to be getting a few cosmetic updates, as evidenced in this latest set of spy photos. Like the smaller Focus, which also received a nip/tuck for the 2015 model year, the C-Max appears to be getting a revised front fascia with slimmer headlamps and a more, shall we say, Aston Martin-like grille. Around back, there looks to be a new bumper with redesigned taillamps, as well.
In other markets, the C-Max people-mover is available with a range of powertrains, but here in the US, it exists either as a traditional gas-electric or plug-in hybrid. The C-Max's fuel economy has been a particular topic of interest lately, with its official fuel economy ratings having been lowered twice since the vehicle's launch. Sales initially suffered a bit following this fiasco, though numbers have since leveled out. It's unclear if Ford is working on any powertrain tweaks for the updated C-Max seen here, however.
Ford has likely spruced up the hatch's interior, as well, though we don't have photos of that at this time. Mum's the word on when we'll see the new C-Max, but our best guess is that it'll arrive sometime in the next year.

VW walks away from Aurora after self-driving startup partners with FCA

BERLIN — Volkswagen has ended its partnership with self-driving car software firm Aurora, two days after the Silicon Valley start-up said it would build autonomous platforms for commercial vehicles with Fiat Chrysler Automobiles. "The activities under our partnership have been concluded," a VW spokesman said in a statement on Tuesday following an earlier Financial Times report on the move which said VW now wanted to work with Ford Motor Co on autonomous driving. Ford's majority-owned subsidiary Argo AI is building an automated "driver" that could compete with Aurora's technology. Aurora said Tuesday "Volkswagen Group has been a wonderful partner to Aurora since the early days of development of the Aurora Driver." The company's statement added that it continues to work "with a growing array of partners." The autonomous vehicle industry is still in its infancy, and alliances and strategies are fluid. Aurora has sought to remain independent and serve a number of would-be autonomous vehicle makers rather than be acquired. Aurora, which said in February it had raised $530 million in new funding, also has partnerships with Hyundai Motor Co and China's Byton to develop and test self-driving systems for automakers, fleet owners and others. After announcing its partnership with Aurora in early 2018, VW last June began discussions with Ford to develop a range of commercial vehicles, later extending the discussions to include electric vehicles and Argo's autonomous driving technology as part of an alliance designed to save billions in costs. VW and Ford have not announced partnerships involving electric or autonomous vehicle technology. Green Chrysler Fiat Ford Volkswagen Technology Emerging Technologies Autonomous Vehicles
