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 spills SEMA all over its Expeditions

If you're going to this year's SEMA Show in Las Vegas, it's going to be tough to miss the Ford booth, simply for its size. The Blue Oval is bringing over a dozen customized examples of the 2015 Mustang and a quintet of modded Transits. The latest announced addition is a trio of upgraded 2015 Expeditions showing different takes on the recently refreshed SUV.
Any vehicle tuned by Dub Magazine needs to ride on massive wheels, and the Expedition (pictured above) that it has for SEMA is no exception. The SUV has 26-inch Dropstars wheels wrapped in Pirelli tires, and, making them look even larger, the suspension is also lowered. The rest of the custom has some mild upgrades like mesh grilles in front, tinted windows, an integrated radar detector and new upholstery inside.
Tijn wants to boost the performance of the 3.5-liter EcoBoost V6 for its take on the Expedition. The company claims to add 40 horsepower to bring total output to a claimed 405 by upgrading the engine with a charge cooler from Vortech Engineering, a custom side exhaust and a custom tune. To match the extra grunt, the SUV also gets bigger brakes, an Air Lift suspension and 24-inch, copper-colored wheels with custom fender flares.

1969 Ford GT40 Mk III found roaming the halls in Geneva

The halls of the 2015 Geneva Motor Show are filled with all manner of exotic racing machinery, from the likes Scuderia Cameron Glickenhaus to McLaren. But there's one peculiar bit of history tucked away that we thought you'd be equally interested to see: a 1969 Ford GT40 Mk III. One of only seven known to be built, this Mk III coupe was intended as a road-going alternative to earlier racing-bred GT40 models, like the original Mk I and 427-cubic-inch, Le Mans-dominating Mk II. Due to its street-legal intentions, the Ford GT40 Mk III boasted revised bodywork that allowed for some luggage and new headlights, along with a redesigned interior with left-hand-drive and a shifter in the normal, center position. The Mk III wasn't very popular when it was new in the 1960s, in part because it looked different from other GT40 models and because it was pretty expensive, but that just means it's an awfully rare gem today. Take a look at the piece of history in our high-res image gallery above.
