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).

Watch this lead sled go rallying in Finland

Custom cars generally fit into neat little boxes in terms of how they are used. For example, you're unlikely to see a modded Corvette going rock crawling; it's just not what it's made for (though we bet it'd look awesome, for a minute). In the same way, chopped, channeled and customized '50s hot rods aren't really meant to go racing. They look great and go fast, but they are generally more cruisers than sports cars.
However, if this video is any indication, the people of Finland don't adhere in these stereotypes, because this rodder is happy to play in the dirt with his lead sled.
According to the video, the driver is a member of the Ford-Freak Club of Finland, and he clearly knows how to have some fun. Possibly inspired by his country's great rally drivers, he gets the tail way out going around this gently curving gravel track. The stunt is somewhat reminiscent of the stock cars races on the sand at Daytona Beach, and this is probably close to what it sounded like too. Scroll down to watch a very cool Finn getting his hot rod a little dirty.

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.
