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).

The 11 most expensive American cars ever

Here's a Pro Tip for all you would-be classic car investors out there: buy Ferraris. With the Pebble Beach festivities kicking off this week, including any number high end car auctions, we thought it would be entertaining to compile a list of some to the most expensive cars ever sold with the bang of a gavel. Trouble is, once you get past the splendor of everyone's favorite Italian sports car maker, that list is pretty boring.
Ferrari dominates the all-time auction sales list; seven of the top ten most expensive cars sold wear the Cavallino Rampante badge, as well as more than half of the top fifty. Sure, a nearly $30-million Mercedes-Benz W196 racecar might be the new top dog as of last year, but it's even possible that Ferrari could take that title back in Monterey this weekend. Long story short: we think a list of the most expensive American cars ever sold at auction is a lot more entertaining to read. Hell, our list has a friggin' Batmobile on it, how can it go wrong?
Follow on below for the top ten cars that are red, white, blue and a whole lot of green.

Winnebago re-introduces classic Brave RV [w/video]

Winnebago is saying 'Let's do the time warp again,' using its new Brave RV to do it – have a look at the first Winnebago RV from 1966 and you'll know exactly where this one comes from. The modern version of this swinging sixties motorhome is accurate from its size, either 26- or 27-foot version, to its trademark eyebrow above the front windshield. The foldaway bunk above the front seats that necessitated the eyebrow design has been updated, and is now a power bed that descends from the ceiling. It is among a set of standard features that also includes a 19-foot motorized awning, leveling jacks at all four corners, heated mirrors, LED ceiling lights, two available floorplans and detailing like a workstation for the front passenger, a sliding dash cluster and and a waterfall countertop in the kitchen with built-in extensions. The Brave sits on a Ford F53 chassis complete with its Triton V10 engine and five-speed automatic transmission. No word yet on any potential diesel alternatives. Naturally, that 1966 price of $4,000 will also come in for an update, but the company hasn't yet revealed it. The good folks from Winnebago will be happy to take you on a thorough personal tour of the Brave in the video below. This content is hosted by a third party.
