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).

Mercury rises around sexy Cougar pack

With a slightly larger body and a more luxurious interior, the Mercury Cougar doesn't carry quite as much cachet among pony car enthusiasts as the venerable Ford Mustang. But don't try to make that argument around Cougar super-fan Mike Brown. Since starting his Cougar collecting in 1988, Brown has become an absolute expert on the model, and he claims to have owned 400 of the Mercury pony cars in that time. Ten of them are in his collection today, not to mention a heap of spare parts in the garage. Check out some of the rarer members of Brown's fleet and allow him to tell you about them in this interesting interview from Electric Federal.

Project Ugly Horse: Part V

The Slippery Slope
I've had a healthy appreciation for cars that stop since one truly unfortunate incident with a runaway 1971 Lincoln Continental.
It's funny how quickly a party can turn from, "We're all having blast" to "What happened to the front of the house, and how many stitches do you think this is going to take?" Standing in a Mustang salvage shop in Kodak, Tennessee, I couldn't help but feel I had strayed into the latter territory with Ugly Horse. There was a supercharged 5.4-liter V8 plucked from a rear-ended Cobra sitting off to my left. The shelves were lined with second-hand Roush and SVT components galore, but I couldn't stop staring at a set of rotors with the approximate diameter of my chest.
