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).

How Ford plans to handle insurance and repair questions surrounding new aluminum-bodied F-150

Building a car out of aluminum has a number of benefits - the lighter weight allows the vehicle to be more agile, more fuel efficient, make better use of its power and be more resistant to dings and dents. The downside to the advanced construction, though, is that repairs are both challenging and expensive. That's troubling for the new, aluminum-bodied Ford F-150, because it's kind of made a name for itself as a rugged, durable work vehicle.
How will the legions of Ford buyers cope when it comes time to insure and repair their new trucks? Well, according to Ford, it's expecting a ten-percent jump in insurance costs for the aluminum-bodied F-150, although Ford's truck marketing manager, Doug Scott, was quick to point out that the F-150 is generally cheaper to insure than its competition from Ram and General Motors. "At the end of the day, that's sort of a wash," Scott told Automotive News at last week's Detroit Auto Show. "We've spent a lot of time and feel very comfortable that that's not going to be an inhibitor."
The other issue facing Ford is the distinct lack of body shops that have the training or equipment to repair aluminum-bodied vehicles. AN cites an estimate from the Automotive Service Association claiming that of the 30,000 independent body shops in the US, less than 10 percent are able to work on aluminum.

Top Gear's latest trailer shows off a golden Bugatti Chiron

Top Gear is returning on March 5, and after a lackluster first series with the new hosts, the new group seems determined not to hit a sophomore slump. Chris Evans is gone, and the latest teaser trailer shows the new trio of Matt LeBlanc, Chris Harris, and Rory Reid strapped into some pretty fantastic cars, including the Bugatti Chiron and the Ford GT. All of the typical Top Gear segments appear to be present, though the quick cuts don't give us many details. The trailer shows a copious amount of powerslides from an assortment of cars, and even Chris Harris racing around Daytona. Aside from the Bugatti and Ford, cars from Porsche, Lamborghini, Ferrari, BMW, Aston Martin, and Alfa Romeo are all present. Co-hosts Eddie Jordan and Sabine Schmitz don't appear at all, so it seems their roles may be downplayed to focus on three guys, as was the case pre-reboot. We have some hope for this re-relaunched show and will be keeping an eye out for more details in the lead-up to the series premiere.
