Spy shooter claims proof of upcoming aluminum Ford F-Series Super Duty

Ford has already confirmed that the 2015 F-150 (pictured above) was just the beginning for its more extensive use of aluminum. CEO Alan Mulally said it himself during the 2014 Detroit Auto Show. We've even already seen the future Raptor testing with an aluminum body. But a recent discovery from an intrepid spy photographer might indicate that the lightweight metal is coming to the Blue Oval's Super Duty pickups in their upcoming generation, as well.
According to Automotive News, a spy shooter in Colorado spotted a prototype for the next-gen F-350 testing. He happened to have a magnet on hand and got close enough to check the truck out. When he held it up to the metal in the bed, it didn't stick, which signaled to him a switch from steel to aluminum.
Obviously, this claim raises some questions. Given that it was a test vehicle, one possibility is that the Blue Oval is just evaluating the feasibility of switching to aluminum for the Super Duty trucks, not necessarily committed to it yet. Ford has been testing it quite exhaustively, after all. In fact, much of the rest of the truck in question was covered in camouflage, so it's possible that the magnet failed to work along the rest of the body not because it was aluminum, but because it wasn't powerful enough to get through the disguising material. Thus, the lightweight metal's use could be far less substantial than on the new F-150. Still, it was a clever idea for the cameraman to check things out and might have given us the first hint about brand's next heavy-duty models.

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).

New car market raining on convertibles' parade

Whether fitted with soft or hard folding lids, today's droptops are better than ever for year-round motoring. Advancements in power top mechanisms, sealing, aerodynamics, structural rigidity, rollover safety and creature comforts like heated and cooled seats mean that modern convertibles are more versatile and better to drive than ever before. Yet the segment's sales took a dive during the recession and haven't come back, Automotive News reports.
Part of that is because automakers are looking at today's more sensible buyers and simply not developing as many new models, and that lack of fresh iron is curbing sales. AN cites R.L. Polk data which notes that only about one percent of new vehicles registered in the US last year had tops that folded. Back in 2009, it was 1.4 percent, and it was 2 percent in 2006. All-in, some 151,636 convertibles were registered in 2012. That's more units more than were registered in each of the past three years, but the market has also grown as the economy has picked up speed, and as a percentage of new vehicles purchased, convertible sales are lagging.
Thus far in 2013, the Ford Mustang is America's top-selling convertible, with 6,421 units registered through the end of April, followed by its rival, the Chevrolet Camaro, at 4,751 units. The Volkswagen Beetle isn't far behind, with 4,305, but from that point, it's a steep drop off to the fourth-place Mercedes-Benz SL-Class and its 2,380 sales.
