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).

2018 Ford Expedition spied looking stylish

The Ford Expedition and Lincoln Navigator got a cool reception for their 2015 warmed-over redesign. But with big, high-riding vehicles once again in vogue, Ford is pushing ahead with a ground-up redesign of its biggest SUVs. Based on these spy shots, the Expedition will continue to serve as the Navigator's more affordable twin. Yes, that's a bold prediction, considering we still haven't spotted Lincoln testing the new Navigator, but study the greenhouses on this Expedition prototype and the Navigator Concept from New York – from the arrow-straight belt line to the extra-long rear window to the aggressively raked windshield, this Expedition's overall profile is broadly similar to what Lincoln previewed earlier this year. While our spies claim the new Expedition will look to the F-150 for design inspiration, we see a departure from past Expedition tradition. Unlike the supposed Expedition spy shots we showed you nearly a year ago – which was nothing more than an SUV with an F-150's nose grafted on, this prototype's front-end styling looks softer and more aerodynamic, with a smaller grille and headlights, almost like an Escape or Edge. This kind of change would explain the additional front-end camouflage. In back, our spies rightly point out that Ford fitted a faux rear end to disguise the rear window's rake – expect the real thing to feature the angled rear window previewed on the Navigator Concept. Look at the last image in the gallery for a better idea of how the Expedition's rear window will actually look. We can't say a lot about the taillights, because of the camo, but non-LED taillights are present. We'd expect Ford to offer LEDs on higher trim levels. While the F-150's styling might not make the transition to the Expedition, its powertrains and emphasis on lightweight aluminum will. Our spies report the biggest SUV will ride on a new T3 platform and feature an aluminum body, with the F-150's 3.5-liter EcoBoost V6. Expect a ten-speed automatic transmission and start/stop tech for sure, while the smaller 2.7-liter, twin-turbo V6 could slot in as the Expedition's base engine – we're less sure on that one. And we're even more uncertain of the rumors of an Expedition Hybrid. Our spies report it could mate a 3.5-liter V6 with an electric motor(s) and battery packs for a more economical full-size SUV. Expect to see the 2018 Expedition debut in January, at the 2017 Detroit Auto Show.

Recharge Wrap-up: Mercedes B-Class Electric Drive is a rock star, FedEx tests electric trucks

The Mercedes-Benz B-Class Electric Drive is in a new music video for I Lived by OneRepublic. The band's singer, Ryan Tedder, has also been brought on as a brand ambassador for the German automaker. OneRepublic will also be performing the song at the Mercedes-Benz Media Night on the eve of the Paris Motor Show. No word if Mercedes plans to offer hordes of screaming teenage fans as an option package with the B-Class Electric Drive. See the video (the car shows up around the four-minute mark) or read more in the press release below. FedEx is testing converted electric delivery trucks with diesel range extenders. Looking to shrink its carbon footprint, the company has converted a handful of trucks as part of a pilot program. In addition to battery packs, each truck is equipped with diesel turbine generators (supplied by Ian Wright's company, Wrightspeed) to provide electricity when the battery is depleted. Because the diesel motors aren't powering the vehicle directly, they can continuously run at their most efficient speed, making the trucks about twice as efficient as those powered by traditional means.

The fuel economy gains depend on the particular version of the truck, but the biggest improvement will likely come from the 3.5-liter V6 and the 2.7-liter EcoBoost V-6. Automotive News predicts the F-150 SFE to be rated at 21 mpg city/28 highway/23 combined, which are identical figures to the Ram 1500 EcoDiesel. The result could be a noteworthy fuel economy battle between Ford and Ram trucks. Learn more at Automotive News. The US Department of Energy is providing $25 million in funding toward reducing the price of algal biofuels. The goal is to get the price of these renewable fuels below $5 per gasoline gallon equivalent (gge) by 2019, and less than $3 per gge by 2030. The money will fund projects to develop better algal cultures that produce biofuel and other useful bioproducts, and projects to boost biomass productivity. The DOE says it wants to help develop a "bioeconomy" that provides jobs, helps the environment and ensures energy security. Read more at Energy.gov. This content is hosted by a third party.
