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).

Project Ugly Horse: Part VII

Devils, Details and Weight Reduction
There are many things I could call this exercise. A party is not one of them.
I've spent three days crammed in the axle well of this 1989 Mustang with nothing to keep me company beyond a trouble light, a DeWalt drill on the very last of its legs and billion razor sharp, red hot slivers of metal with an affinity for my most sensitive of regions. My joints are raw from crawling around on the concrete. I'm half deaf from the shriek of the spot weld cutter and the boom of the cold chisel and hammer.

How Ford secretly used customers to test its aluminum F-150 [w/video]

Automakers getting clever about disguising development vehicles isn't anything new. Between mules wearing the sheetmetal of other cars and prototypes decked out in as much camouflage as is practical, automakers know how to make it very difficult for the general public to get an exact idea of what kind of vehicle is in development. Ford, though, is rapidly becoming the master.
We knew that the Blue Oval originally tested the durability of the aluminum construction being used for the 2015 F-150 by building an all-aluminum 2014 truck and entering it in the Baja 1000 off-road race. That's no longer a secret. What we didn't know, though, is that the aluminum development dates back to before even that, and that some of the people in question had no idea what it was they were working with.
Ford says this is the first time prototypes have ever been handed over to the public.
