2015 Ford F-150 First Look
Can Aluminum Beat Chevy and Ram Attempts at Pickup One-UpsmanshipThe veil has been lifted, and the questions about the 2015 Ford F-150, debuting at the 2014 Detroit Auto Show, have been answered: Yes, the next F-150's cab and pickup box will be almost entirely made of various grades of aluminum. Yes, magnets will still stick to the steel chassis frame. So yes, towing and hauling capacities (not yet announced) can be expected to increase by roughly the body-mass savings, which are only quantified as "up to 700 pounds."

Let's start right there. Because it's the switch from steel to aluminum in the body that accounts for 70 percent of the weight savings, the bigger the bodywork, the bigger the savings. Hence: short-cab/short box, probably 500 or fewer pounds saved. SuperCrew long-box—maybe a bit more than 700. The big volume SuperCrew short box should come in around the 700-pound mark. The only major piece of the body sheet metal that is not aluminum is the Quiet Steel laminated sound-absorbing firewall -- aluminum just can't match its performance for hushing engine noise.
While Ford is being coy about defining the alloys used, we're told they're the same as used in military HMMWVs and aerospace applications. The engineering team learned about aluminum when assisting with the development of the original aluminum Jaguar XJ. We're assured that it will resist dents and dings better than steel, and that it will not be substantially more expensive to repair (and hence to insure).
Roughly 70 pounds were saved in the chassis, by increasing the percentage of high and ultra-high-strength steel alloys (up to 70,000-psi tensile strength) from 23 to 77 percent. These alloys reportedly outperform aluminum in terms of overall rigidity and other factors. The rest of the weight savings come from things like a lighter transfer case. There isn't much "cascade effect" light-weighting of other components due to the lighter bodywork, as you typically get in a passenger car, because there's little or no downscaling of the gross vehicle weight or gross combined weight ratings. So brakes still need to be able to stop the same mass, for example. The idea is, you can save fuel when the truck is empty, or you haul more weight.
