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).

Sunday Drive: Still thankful for supercars

The Thanksgiving holiday meant that last week was pretty short on stories, but apparently our readers are still thankful for supercars. The biggest news of the week was the new Aston Martin Vantage, which is clothed in a new look that Autoblog readers are still very much unsure of. It's a radical departure from past Aston Martin models, and while everyone seems to agree that the profile is lovely, the squinty headlamps are a particular source of contention. Its 503 horsepower and 512 pound-feet of torque cannot be argued with ... oh, and a V12 may be coming soon. Moving along is a nearly new 2006 Ford GT for sale that's expected to fetch around $300,000 at auction. It's so unused that it still has plastic wrap covering the leather interior. The Ango-American theme continues with the McLaren 720S, though not in road-going form. Still, renderings of the upcoming 720S GT3 racer round out this supercar-rich recap. As always, stay tuned to Autoblog for all the latest automotive news that's fit to print.

Jay Leno drives postcard-perfect '32 Ford Highboy Roadster

At the turn of the century, it was arguably the Honda Civic that best defined inexpensive performance tuning, and in the '50s it was the Tri-5 Chevys. One of the earliest platforms to gain a huge following among young people looking for a cheap way to go fast was the classic '32 Ford Highboy Roadster. This week, Jay Leno's Garage looks at one of the very first vehicles that defined the look of the hot rod heyday.
This '32 Ford was built in the '40s and graced the cover of the fourth issue of Hot Rod Magazine back in 1948. All of the hot rods that you see shining at car shows today owe a serious debt of gratitude to this roadster. It bears all of the cues that define the look, including a notched frame and hidden door hinges. Under the three-piece hood is a flathead V8 boasting all sorts of period modifications, including copper cylinder heads. It was seriously fast in its era too, and proved it by reaching 112.21 miles per hour on a dry lakebed in 1947.
These days, this hot rod is on display at the Petersen Automotive Museum. Although, if you can't make it to California to see it, the United States Postal Service is celebrating this Ford with one of its two hot rod Forever stamps. Like Jay says in the video, in terms of hot rodding, "it all comes back to this." Check out the video to learn more about this rolling piece of tuning history.
