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).

2016 Ford Focus RS may yet be AWD, US sales likely

When it comes to forbidden fruit, few vehicles are spoken of in as hushed a tone as the Ford Focus RS. The turbocharged, five-cylinder hot hatch could only be seen from afar by American customers as it tore up the roads of Europe. And while it's safe to say that Ford's Yankee fans are quite happy to now be on equal footing with drivers in the old country thanks to the Focus ST, we doubt there'd be much protestation over a successor to the RS arriving stateside.
Of course, we've seen images of the new RS undergoing testing, but a new story by Road and Track aims to fill in some very large blanks in our knowledge of that car, thanks to a pair of mysterious insiders at the Ford. Chief among those is this - the RS will almost certainly make its way to the US, albeit in limited quantities. It gets better, though.
Under hood, the new RS is unsurprisingly expected to borrow the 2.3-liter, turbocharged four-cylinder from the 2015 Ford Mustang and 2015 Lincoln MKC. While that twin-scroll turbo produces 310 horsepower in the Mustang and 285 ponies in the MKC, R&T expects the RS to deliver quite a bit more firepower - 325 to 350 hp, with preference going to the higher output due to the limited-edition nature of the RS. This roughly fits with previous reports.
