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 to hack $4k off price of Focus EV amid slow sales

Between slow sales and a hefty price drop for its nearest rival, the Ford Focus Electric may be looking at a pretty substantial price cut. The Detroit News is reporting that Ford will drop the price of the all-electric by about $4,000 to $35,200 to be more competitive with the Nissan Leaf, which received a big price cut for 2013 down to $28,800.
Ford has already admitted to having low expectations for the car's sales and massive rebates were reported earlier in the year, but there is still no official word from Ford on this matter. The company's consumer site still lists the 2014 model's starting price as $39,200. In addition to the Leaf, the Focus Electric will also have to deal with the lower prices of smaller EVs including the Honda Fit EV, Fiat 500e and the Chevrolet Spark EV.

Sunday Drive: Big debuts from the Big Apple dominated the headlines

New York Auto Show week has come and gone, and, not surprisingly, the week's biggest bits of news came from the halls of the Jacob K. Javits Convention Center in NYC. Our favorite debut from New York was the Lincoln Aviator, a sharp-dresses crossover that looks lovely inside and out, and sits on underpinnings at least partly derived from the Ford Mustang. While the Aviator may have caught our attention, it wasn't the most popular vehicle debut from New York, at least when judging by the number of page views here on Autoblog. That distinction goes to the 2019 Toyota RAV4, and we're hardly surprised. The RAV4 is the most popular compact crossover in America (in fact it's the most popular vehicle that isn't a pickup truck), and the 2019 version looks like a radical departure from the model that came before. We can't wait to drive the thing. Midsize sedans may not be the darling of the family car set, that honor taken over by the aforementioned crossover, but they still sell in large enough numbers that a brand-new model catches our attention. Such is the case with the 2019 Nissan Altima. We broke down the specs of the Altima and compared Nissan's bread-and-butter sedan with its biggest rivals. And finally, we got some official figures for the 2019 Ford Mustang Bullitt. It'll cost a cool $12,000 over the cost of a Mustang GT, and will benefit from a 480-horsepower, 420-pound-foot version of Ford's excellent 5.0-liter V8 engine. As always, stay tuned this week for all the latest automotive news that's fit to print. 2018 New York Auto Show Mega Photo Gallery | Start spreading the news 2019 Toyota RAV4 actually looks pretty cool 2019 Nissan Altima vs Honda Accord vs Toyota Camry: How they compare 2019 Mustang Bullitt orders open as Ford reveals price and horsepower Image Credit: Drew Angerer/Getty New York Auto Show Ford Lincoln Nissan Toyota Coupe Crossover SUV Sedan 2018 new york auto show
