2015 Ford F-150 shaves 700 pounds, adds 2.7-liter EcoBoost [w/video]

The Ford F-150 is one of the best selling vehicles on the planet. Considering that, one can imagine that when it comes time for a redesign, there are hardly any half measures. For its lucky thirteenth generation, Ford has gone all-in on the single most important vehicle in its portfolio, redesigning it from the ground up.
The big news is the F-150's new, lightweight, Atlas-inspired body. Ninety-three percent of that new body is made from a sort of aluminum alloy not unlike what the US military uses in its M2 Bradley fighting vehicles and Humvees, and it accounts for up to 70 percent of the F-150's 700-pound weight reduction. As a side benefit, the aluminum body should prove more resistant to dents and dings. Built Ford tough, indeed.
If you're wondering where the other 30 percent of that 700-pound weight loss went, 8.5 percent (60 pounds) came from the increased use of high-strength steel (up from 23 percent to 77 percent) in its ladder-box frame. Ford claims this steel is comparable to some of the heavy duty pickups used by its competitors, with a PSI rating of 70,000.

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.
