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).

Chris Harris checks out Ken Block's Hoonicorn '65 Mustang

Ken Block's Hoonicorn, which stars in Gymkhana Seven, might still bear a passing resemblance to a vintage 1965 Ford Mustang, but underneath the skin, the car is one of the baddest custom machines to ever do a smoky burnout on the road. The ever enthusiastic British auto journalist Chris Harris is now showing what really makes Block's new ride tick on video, and Harris even gets to go for quite a ride. The only Mustang components really left on the Hoonicorn are the A-pillar, B-pillar and roof, according to Harris. Everything else is ditched to create Block's ultimate Gymkhana tool. The 845-horsepower, 6.7-liter Rousch Yates V8 sits behind the front axle, and the grunt is routed to all four wheels through a Sadev gearbox usually found on Dakar Rally vehicles. The whole drivetrain is packed with cool little touches; like that giant handbrake that also disconnects power from the front wheels when in use. The superlatives about the Hoonicorn could go on forever, but settle in and let a very excited Harris tell you about just some of them. He's like a kid in a candy store here, and the look that combines surprise, fear and joy during his ride with Block is the kind that lacks a suitable word in the English language.

New Ford dedicated hybrid due in 2018, will it fare better than C-Max?

Everyone likes to go after the champ. When it comes to fuel economy, that means taking on the Prius, which is something that automakers not named Toyota have been trying to do for years. Just because no one has been able to beat the Prius for fuel economy numbers isn't stopping them from trying. Hyundai was just caught with a potential Prius-fighter and now we have news that Ford is joining the party. Well, is going to join again. The last time Ford said it was going to challenge the Prius, it didn't go quite as planned. The C-Max hybrid was heavily hyped as a Prius-beater and was originally rated at 47 miles per gallon. Of course, it later needed to be recalculated to just 40 mpg and sales tanked. So, it's back to the Blue Oval drawing board, according to Automotive News, which is reporting that Ford is readying a brand new gas-electric hybrid due in 2018 as a 2019 model year vehicle. A plug-in version is in the works, too, and the car will reportedly share a platform with the upcoming next-gen Focus and Escape models. About those C-Max sales. They have not been stellar for the C-Max hybrid, which started strong but suffered when the reality of the lower fuel economy was realized. So far in 2014 (through the end of July), Ford has sold 11,685 gas-electric models and another 4,759 plug-in Energi versions. The trend for the standard C-Max is downward (from 20,125 during the same time frame in 2013) and upward for the plug-in version (2,915 in the first seven months of 2013).
