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).

Watch Piquet and Mansell bend some sheetmetal in Ford Fusion GP

As we told you about before, there were four episodes planned for the Ford Fusion GP campaign in Brazil, and the whole series has now run its course. The Ford ads pit Brazilian Formula One driver Nelson Piquet against English F1 pilot Nigel Mansell driving the new Fusion, the two coming together again after their partnership at the Williams F1 team ended in a miserable state more than 20 years ago.
They're lined up for you below, in reverse chronological order. You should watch number three first, though, as it adds a bit more spice to the NASCAR action in the fourth.

Driving the 2021 Genesis G80 and Toyota Sienna | Autoblog Podcast #652

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder. They kick things off by talking about driving the all-new, 2021 Toyota Sienna hybrid minivan and Genesis G80 luxury sedan. Next, they talk about what of GM vehicles Autoblog staff members would like to restomod with the new Connect and Cruise eCrate motor and battery package. They also discuss the pros and cons of Ford CEO Jim Farley's decision to continue racing. Finally, they reach into the mailbag and help a listener pick a new car to replace a 2016 Mazda Miata.
