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).

Galpin Auto Sports and Fisker turn the Mustang into a Rocket in LA [w/video]

Galpin Auto Sport and Henrik Fisker made big promises about the Rocket before its debut at the Los Angeles Auto Show today, calling it the "ultimate American muscle car." Now that this 725-horsepower carbon-fiber Ford Mustang has officially been revealed, we've now got a chance to see if their vision backs up all the bluster. The Rocket is based off the latest 2015 Mustang, but the entire exterior design has been substantially reworked by Fisker. "This is a project born out of passion, it's a dream come true, to have the opportunity to 'touch' a Mustang and apply my design ideas to it," he says in the model's announcement. The biggest changes come up front, where Fisker has added a gaping hexagonal grille with a polished bar running and two nearly hidden driving lights at the top corners. Long nostrils run down each side of the hood, taking their inspiration from the 1968 Shelby GT500. The Rocket's design also emphasizes its scalloped sides, which run back to functional ducts at the rear to cool the Brembo Grand Turismo brakes. When checking out the Rocket from the rear, it's easy to spot the wider fenders that are beautifully blended into the integrated spoiler. The interior has been left mostly alone beyond some eye-grabbing red leather and carbon-fiber trim. Under the hood, Galpin spokesperson Nathan Hoyt has confirmed to Autoblog that the Rocket employs a 5.0-liter V8 with a Whipple supercharger which can be called to attention with a six-speed manual gearbox. It took only a few months for the vehicle to go from conception to reality. Fisker showed Galpin President Beau Boeckmann early sketches at this year's Pebble Beach Concours d'Elegance, and the two parties went from there. "When Henrik showed me his ideas, I got chills - it's literally the most beautiful Mustang I have ever seen," says Boeckmann in the company's release. Production is set to begin in December, with deliveries starting in early 2015. There's no set production total in mind for now, but Hoyt tells Autoblog that the price will be "just over $100,000."

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.
