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).

2015 Ford Focus ST gets sleeker style, improved dynamics

The Brits don't really have a major auto show these days. Not in a conventional sense, anyway, with stationary vehicles under floodlights in a closed exposition space. What they do have, you could argue, is much better: the Goodwood Festival of Speed, where the public can view the latest machinery not only under an open sky, but in motion as well, speeding up Lord March's front lawn. And this year, British automakers are rolling in with some very enticing new metal.
In the past few days alone we've confirmed the McLaren 650S GT3 and MSO, Jaguar F-Type Project 7, Range Rover Sport SVR and Ariel Ace will all be revealed for the first time at Goodwood this weekend. Ford isn't, strictly speaking, a British automaker, but for all its history in the UK, it might as well. So it's chosen Goodwood as the site to unveil its refreshed Focus ST.
The upgraded Blue Oval hot hatch still packs a 2.0-liter turbo four with 252 horsepower and 270 pound-feet of torque driving through a six-speed manual to the front wheels, so we're not expecting much change in measurable performance. But Ford has given the new Focus ST a new front suspension setup and a new electric power-assisted steering rack that combine to promise improved handling.

Autoblog Podcast #317

Mitsubishi Mirage, Toyota thinks of beefing up US production, Marchionne on Alfa, Dart and minivans, Ford Atlas concept, Honda Gear concept
Episode #317 of the Autoblog Podcast is here, and this week, Dan Roth, Jeff Ross and Michael Harley bookend the other podcast topics with a pair from the Montreal Auto Show, the Mitsubishi Mirage and Honda Gear concept, and in between we talk about Toyota building all its US-market cars stateside, Hyundai building a Nurburgring test facility, Sergio Marchionne's latest words about Alfa Romeo, Dodge Dart powertrains and the future of Chrysler vans. Some chatter about the Ford Atlas concept finishes up the meat of the 'cast and then we wrap with your questions. For those of you who hung with us live on our UStream channel, thanks for taking the time. Keep reading for our Q&A module for you to scroll through and follow along, too. Thanks for listening!
