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).

Volvo to shake off Ford ties with new platforms, engines

It would seem Volvo is finally getting around to throwing all of Ford's things out of the apartment. Automotive News reports the Swedish automaker is preparing to unleash a range of new engines as well as a fresh platform designed entirely in house. The powerplants include an all-new four-cylinder engine set to bow before the end of this year before arriving in the US by 2014. Shortly thereafter, the world should get its first glimpse at the next-generation XC60, which will the company's first model to make use of the Volvo scalable platform architecture (SPA). US buyers can expect to see that machine on their roads by early 2015.
The next V70 and S80 will also use the SPA, though those models will carry V90 and S90 designations when they hit dealer floors. But that doesn't mean Volvo has completely weened itself off of Ford technology. The V40 will continue to ride on Ford bones until the model's next chassis can be co-developed between Volvo and Geely.

Car-crazy 5-year-old boy writes automakers for treasures, gets big response

Part of the beauty of children is that they can find worth in something adults might deem unworthy or overlook entirely. Five-year-old Patch Hurty didn't see garbage or a broken piece of a car when he spotted a Ford badge lying on the side of a road. He saw an artifact, a souvenir, a start to a collection he could only dream of. Ezra Dyer of Popular Mechanics tells the story of Patch and his quest to turn that one lost badge into a museum of manufacturer logos. According to the article, Hurty is a car fanatic through and through, even using car names as a way of learning to read. After finding the Ford badge near his Connecticut home, he and his mom put together a plan to reach out to dozens of automakers, confessing his love of things on four wheels. In each letter, Patch assembled a picture of himself standing next to one of the cars, and a penny to pay for whatever he hoped was sent his way. The response was unexpectedly and overwhelmingly positive. Of the more than 50 letters he sent out, including to obscure or defunct companies such as Bugatti, Suzuki, and Saturn, a majority responded with warm notes and some type of souvenir. Two of the coolest responses came from Lincoln and Bentley. Lincoln sent a sketch of a Continental (all car lovers enjoy drawing cars, right?), and Bentley sent a wheel center cap. How awesome is that? The story reminds us of something that can easily be lost in all of the negativity involved with the auto industry: Everybody is in this because of a common infatuation with automobiles. For more details on the souvenirs Patch received and accompanying photos, read the rest of the story. Related Video: News Source: Popular Mechanics Read This Bentley Bugatti Ford Lincoln Saturn Suzuki
