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).

Black Zombie electric Mustang launches Blood Shed Motors [w/videos]

As patient zero of Blood Shed Motors, the classic pony car has received a powerful electric transplant. Lightning repeatedly vanquished the darkness like the angriest of strobe lights and thunder shook the building, punctuating the clatter of a heavy Texas rain on the metal roof as the clock ticked away the initial seconds of a rare full moon Friday the 13th. It was then that the Black Zombie came to life for the first time. Beneath the hood of this rust-free 1968 Mustang fastback, a 289-cubic-inch V8 no longer turns gasoline into heat, noise and pollution. As patient zero of Blood Shed Motors, the classic pony car has received a powerful electric transplant, and now boasts twinned Warp 11 DC motors and a pair of fresh Zilla controllers that will serve as the basic blueprint for future vehicles. Dubbed the Zombie 222 drivetrain, the setup will be limited to 750 horsepower in customer's cars to keep the maintenance experience low, and eventually will draw power from a 40-kWh battery pack. In this first example, though, the output is bit more extreme. For one day, at least, they have the 1,500-kW-capable pack that powers the record-setting Swamp Rat 37 racer belonging to Don Garlits and a brief window of opportunity to try it out on a track. Blood Shed Motors is the result of a collaboration between NEDRA co-founder John "Plasma Boy" Wayland, the man who helped bring electric vehicle drag racing to the attention of the world with his unassuming White Zombie Datsun 1200 conversion and Austin, TX business man Mitch Medford, who've put together a small team of experts in their chosen fields. The plan is to build a limited number of muscle car conversions on pristine early Mustang, Camaro, and Barracuda platforms. The plan is to build a limited number of high-quality muscle car conversions on pristine (No restored rust buckets!) early Mustang, Camaro, and Barracuda platforms. Each can be customized according to buyer's wishes and blessed with its own serial number. The price tags will be in the eye-watering $200,000-and-up neighborhood, reflective of the cost and rarity of these cars and the custom nature of the alterations. Of course, you can't just multiply horsepower and add the monster torque that these electric motors put out and expect an antique chassis to hold up.

Editors’ Picks October 2022 | Electric trucks and some excellent SUVs

This month sees a bevy of totally new or totally redesigned cars gain Editors’ Pick status. Important EVs like the F-150 Lightning and GMC Hummer EV quickly jump into the list, and they do so with authority, as all our editors love these trucks. The Range Rover is always a superb experience, and this generation proves to be no different. Plus, the new generation of Kia Sportage continues to surprise and impress. In case you missed our previous Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in October that earned an EditorsÂ’ Pick. 2022 GMC Hummer EV The Four-Wheel-Steer system lets the 2022 GMC HUMMER EV Pickup m View 17 Photos Quick take: The Hummer amazes as an electric supertruck with its wild acceleration, incredible off-road capability, luxuriousness and epic utility. It's far from a "green" eco-friendly vehicle, but that's not the point of this technological powerhouse. Score: 8.5 What it competes with: Rivian R1T, Ford F-150 Raptor R, Ram 1500 TRX Pros: Stupid quick, tons of tech, off-road capability in spades Cons: Not efficient, annoying in tight spaces, price From the editors: Road Test Editor Zac Palmer — "I don't think I've driven a more ridiculous vehicle this year, but that's sort of the point with the Hummer. There's a great argument against this sort of EV in that it doesn't live up to being an efficient and planet-friendly vehicle, but hey, that's not the point. The Hummer EV is a supertruck and wild technological masterpiece for off-roading in the same way that a mid-engine supercar is to track performance. It's not meant to be the EV everybody drives to work and back (mostly because few can afford it), but it serves as a line in the sand of what can be done with electric off-road trucks. This pickup rules, and if you can afford one, you're going to love it." Senior Editor, Green John Beltz Snyder — "This Hummer revival is a showcase of technology and capability on the part of GM, making it an absolute blast to drive and a joy to use.
