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).

Automakers, dealers are rushing cars to Houston after Harvey

DETROIT — Houston-area car retailers and automakers are rushing to reopen dealerships and beef up inventory to replace many hundreds of thousands of vehicles damaged in flooding from Hurricane Harvey. Pete DeLongchamps, vice president for manufacturer relations at Group 1 Automotive, the third-largest U.S. auto dealer group, said the company prepared for the storm with a plan designed after Hurricane Katrina in 2005. This included moving moved inventory to higher ground and cleaning roof drains to avoid cave-ins. Group 1 thus lost a "relatively small percentage" of inventory and reopened its roughly 25 dealerships in the Houston and Beaumont area by Thursday. "Things have been moving fast and furious with a large number of tow-ins already," DeLongchamps said. "Our customers have lost a lot of vehicles, we need to help them replace." Harvey brought record flooding to Houston and killed at least 35 people. The storm is expected to briefly depress already slowing U.S. auto sales but could eventually help boost demand as damaged cars are replaced. Automakers report U.S. August sales on Friday. Estimates for the number of Harvey-damaged vehicles needing replacement range up to 500,000. By Thursday, AutoNation, the largest U.S. auto retail chain, had reopened its 17 Houston stores and is moving cars and trucks from other regions, company spokesman Marc Cannon said. The company plans to move 500 to 1,000 used cars to an AutoNation USA used car store and stage a sale Sept. 21-23, when many would-be buyers should have insurance checks to replace destroyed vehicles, Cannon said. AutoNation is still assessing how many vehicles it lost, but it too moved vehicles to higher ground ahead of the storm. General Motors spokesman Jim Cain said the number of damaged vehicles at dealerships "is relatively modest." "But there are still several dealerships that are inaccessible, so the number will increase," he said. GM will move new and used vehicles to Houston, "but it won't be done until the infrastructure and our dealers are ready." Ford is still assessing damage and inventory needs, a spokeswoman said. CarMax, the biggest U.S. used car dealer, will reopen its six Houston area stores on Labor Day, spokeswoman Claire Hunter said. "We are mobilizing additional inventory to the region as we speak," Hunter said.

Ford recalls nearly 1.3 million Fusions, Lincoln MKZs for brake hose leaks

Ford Motor is recalling nearly 1.3 million Fusion and Lincoln MKZ sedans built from the 2013 through 2018 model years because their front brake hoses may rupture and leak brake fluid, which could affect stopping ability and increase the risk of a crash. The company notified the National Highway and Transportation Safety Administration and says that in the event a leak occurs, the brake fluid warning light may illuminate on the instrument cluster behind the steering wheel. Dealers will replace the front brake hoses, free of charge, and notification letters to owners are to be mailed in mid-April. A second letter will be mailed once replacement parts are available. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23S12. The vehicles affected were manufactured between Feb. 3, 2012, and July 19, 2017. In mid-2020, Ford recalled 488,594 Ford Edge and Lincoln MKX SUVs for a similar problem regarding leaking brake lines.   Recalls Ford Lincoln Safety
