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).

Will Ford's SUV blitz include the Bronco?

Ford announced this week it will add four sport-utility vehicles in the next four years, an ambitious bet on a segment the industry once shunned. This led to wild speculation about what form these utes will take. Here's what we know: They will be new nameplates, and Ford is thinking globally. That means at least one might not be a product with US intent. They will also be in segments where the company does not currently compete, Ford said. The Blue Oval isn't specifying exactly what's it's doing, so here are some of our theories. We think one will be called the Bronco, which is great news for enthusiasts. We hope it follows the Mustang playbook with some heritage styling, but a thoroughly modern execution. Ford needs an off-road Jeep Wrangler-fighter. Fuel prices are low and it's been 22 years since the infamous O.J. Simpson white Bronco chase. This is the best chance Ford will ever have to bring back this iconic name. Our man on the ground at the Chicago Auto show, Sebastian Blanco, reported that Ford sales and marketing vice president Mark LaNeve said a "mini utility" will also be one of the utes. This could be primarily an overseas play. We've also seen lots of spy shots of the EcoSport, a small crossover that Ford sells in India and other overseas markets, being tested on American roads. That is an existing nameplate. Maybe Ford adds a small ute related to the EcoSport in the United States, but calls it something else. We think Lincoln gets a three-row SUV out of the deal. It could slot between the MKX, which was new last year, and the Navigator. Lincoln is leaving money on the table by not being in this segment. The platform could be used for a Ford at some point, too. The Blue Oval brand does actually have a tweener three-row vehicle, the Flex, but this chassis might underpin a replacement. Or maybe Ford makes one of these a hybrid. The company laid out ambitious plans in December to ramp up its electrification strategy, something that could mean a dedicated hybrid SUV (Kia unveiled one of those right after LaNeve's speech in Chicago). It's also possible hybrid technology will be integrated into this new portfolio. The Escape used to have a hybrid sibling. Whatever form they ultimately take, Ford is betting heavily on SUVs. The company thinks they are what Baby Boomers and Millenials want and expects the segment will continue to grow. It's important to note: this will be a diversified strategy.

1 in 7 Americans say they might buy an EV next, as sales of electrics surge

About one in seven driving Americans may likely purchase an electric vehicle as their next car, according to an AAA poll, meaning that as many as 30 million Americans may pony up for an EV within the next three to five years. While some of the motivation is environmental, survey recipients say that lower maintenance expenses and solo access to high-occupancy-vehicle lanes are also among the factors behind potentially going electric. Take a look at the AAA press release on the study here. The poll indicates that about as many people are planning to buy an EV for their next car as are looking to buy a pickup, which is impressive given that the best-selling US vehicle is the Ford F-150. And things should only improve, as about 20 percent of millennials polled said that their next car would probably be an EV. The results are all the more encouraging, at least among green-car advocates, because gas prices have fallen about 40 percent within the past five years, meaning that there's less of an incentive to go electric from a purely economic perspective. Through the first quarter of this year, US plug-in vehicle sales were up about 63 percent from a year earlier to about 39,000 vehicles. Meanwhile, when it came to AAA's annual green-vehicle awards for this year, Tesla's Model S and Model X took the large car and SUV categories, respectively, while the Chevrolet Bolt and Volkswagen e-Golf were listed atop the subcompact and compact lists. The Lexus GS 450h hybrid and the Ford F-150 took home AAA's best green vehicle in the midsize and pickup truck categories. Related Video:
