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 Bronco, Bronco Sport, sub-Ranger pickup and GM EVs | Autoblog Podcast #618

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Road Test Editor Zac Palmer. Top of the list this week are the leaked photos of the 2021 Ford Bronco and Bronco Sport. Then they talk about the possibility of a small Ford pickup based on the Focus, as well as all the electric vehicles Snyder saw in person at GM's "EV Day." The editors have been driving the Ram Power Wagon and Hyundai Sonata, and Palmer took Autoblog's long-term Subaru Forester to New Orleans. Finally, they help a listener choose a small luxury crossover in this week's "Spend My Money" segment. then, just as they're about to wrap up the show, they learn that the 2020 New York Auto Show has been postponed due to the coronavirus outbreak.

Ford recalls more than 550,000 trucks and SUVs for various safety issues

Ford announced safety recalls for its current F-150 pickup along with several Ford and Lincoln crossovers early Wednesday. The recalls cover more than 550,000 vehicles and address various safety defects, ranging from a fire hazard to potential loss of braking power.  The most far-reaching of the recalls covers approximately 550,000 examples of the 2015-2018 Ford Edge and 2016-2018 Lincoln MKX, which may have been assembled with defective front brake jounce hoses (also commonly referred to as "flex lines"). These hoses run from fixed points on the chassis to the individual front brake calipers. Defective hoses could potentially rupture, allowing brake fluid to leak and resulting in a loss of braking function. Ford will replace the components in question with revised parts.  The next-largest recall is for roughly 3,000 2020 Lincoln Corsair crossovers. The affected models may have been assembled without proper clearance between their rear suspension springs and toe link brackets. The components could potentially make contact, wearing down the protective coating on the rear coil springs, allowing corrosion to occur over time. This corrosion could eventually lead to a failure of the spring. If this happens while the vehicle is being driven, it could result in a sudden change to the vehicle's handling characteristics, and the spring fragments could potentially cause further damage to the car or surrounding traffic.  Ford says owners will be notified that their Corsairs need to be inspected; if there is not adequate clearance between the rear suspension components, Ford's service technicians will remove material from the toe link bracket to allow for operation without contact.  The final (and by far the smallest) recall is for the 2020 F-150. Some units may have left the factory with the incorrect retention nut on the hot lead to the starter motor. Ford says it can cause increased heat generation or electrical arcing, which could potentially result in a fire. Ford says this issue is limited to just a few hundred examples sold in the United States. Dealers will inspect the vehicles and replace the nut if necessary.
