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 Focus ST checks into Jay Leno's Garage

In a change of pace from the high-end vehicles that often appear in Jay Leno's Garage, Ford sends its hottest hatchback (in the US, at least), the 252-horsepower Focus ST, to be featured on Leno's show. Accompanying the five-door hatch is its chief engineer, Jamal Hameedi.
Riding on stylish 18-inch wheels with summer tires and with a spoiler that doubles as a lunch tray, Hameedi and Leno walk us through the finer points of what makes the ST special, which also includes bigger brakes, torque vectoring, a manual transmission and, of course, 252 hp and 270 pound-feet of torque from the 2.0-liter EcoBoost four-cylinder engine, which is made possible by 21 psi of turbocharged boost.
Watch the video below to see what Leno thinks of the global Focus ST.

2016 Ford Explorer order guide revealed

The configurator for the refreshed 2016 Ford Explorer is already up and running. However, if you're the type of person that really likes to dig into the nitty-gritty of a vehicle's features, then the order guide for this latest Ford is now available (pictured right). While the documents don't list fuel economy, engine power or pricing, they give a precise idea of all of the differences separating each of the five trim levels: Base, XLT, Limited, Sport and Platinum. In addition to the tweaked styling across the board, even the Base model now features a rearview camera with a washer. There are also three new colors available: Shadow Black, Blue Jeans Metallic and Guard Metallic. Base, XLT and Limited trims are available with either a 3.5-liter V6 or new, optional 2.3-liter EcoBoost four-cylinder. All of them are mated to a six-speed automatic, and all-wheel drive is optional with either engine. The new Platinum trim basically loads the Explorer up with everything imaginable. Power comes from the 3.5-liter EcoBoost V6, matched with all-wheel drive. Plus, the Platinum trim gets standard luxuries like a dual-pane moonroof, adaptive cruise control, a premium sound system and Ford's super-soft Nirvana Leather covering the seats. There are also some new tech features throughout the rest of the lineup. For example, an updated auto-parking system is also available on the Limited but comes standard on the Platinum. Furthermore, a 180-degree front camera and second-row USB charging are optional on the Sport but are standard on the Limited and Platinum. Check out the gallery for even more of the changes.
