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 Shelby GT350 Mustang is a track-day weapon with 500 hp

Ford promises more than 500 horsepower and a torque peak above 400 lb-ft.
The wait is finally over. After months of spy shots, rumor and innuendo, Ford has officially pulled the wraps off its new Shelby GT350. Judging by the spec sheet and the promises being made - especially that the Shelby GT350 will be "an all-day track car that's also street legal" - the wait appears to have been worth it.

Ford drops Focus RS teaser ahead of Feb 3 reveal

Ford is trying to get us hyped for the unveiling of the latest Focus RS on February 3 with this new video teaser. The clip showcases the hot hatch doing some big slides in the wet and dry during testing in Europe and the US, and it definitely makes us even more curious about what the Blue Oval has in store with the RS. Even in this short teaser, Ford continues to dress the more aggressive nose of the Focus RS in camouflage, like the previous test cars. Unfortunately, what's going on under all of that concealment remains a bit of a mystery. Rumors suggest the RS likely uses a tuned version of the Blue Oval's 2.3-liter turbocharged four-cylinder estimated to make between 325 and 350 horsepower. A speculated torque-vectoring all-wheel-drive system should keep fears of torque steer at bay, and larger brakes on the test mules indicate that bringing it all to a halt shouldn't be a problem, either. We do know that the hotter Focus will be among the "more than 12" vehicles that the new Ford Performance division will develop through 2020, and the RS will come to the US for the first time. However, US-spec RS models will likely be imported from Europe, which will keep numbers here low and will mean prices estimated to be around $30,000 or more. Until the official specs become available, at least enjoy watching this hot hatch's ability to slide.
