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).

Ford Mustang GT350 seen and heard in motion for the first time

We just recently saw our first spy shots of the next-gen hi-po Ford Mustang slated to replace the Shelby GT500, but now we're getting our first look - and listen - of prototypes captured on video. Mustang6g.com has the video (along with some different spy shots), which show that, if nothing else, SVT knows how to tune an exhaust system. The :50 mark is a good example of this, but fast-forward to around 2:00 where the driver revs the engine and really gets on the throttle hard taking off from a stop.
There's still no definitive evidence that the next-gen SVT Mustang - said to be called GT350 - will be naturally aspirated, but it sounds just as menacing as the current Shelby GT500. While the video posted below exhibits the sort of quality that is to be expected from someone driving while trying to film someone who is attempting to elude being filmed, it's still exciting to see and hear this new Mustang in motion.

2014 Ford Fusion order guide reveals new base Hybrid model, equipment changes

We've gotten our grubby little digits on the dealer order guide for the as-yet-unreleased 2014 Ford Fusion thanks to an anonymous tipster, and while there isn't much that's unexpected, there are some meaningful equipment changes to report after the rakish sedan's first year on the market.
Mechanically, the big news is, of course, the recently confirmed availability of the 1.5-liter EcoBoost four-cylinder paired with a six-speed automatic. The powertrain replaces the 1.6-liter automatic setup of 2013, though if you want a manual transmission, you'll still get the extra .1-liter of displacement.
On the equipment front, there are newly available rear inflatable seatbelts - as seen previously on the Explorer - along with a new heated steering wheel and cooled seat option on Titanium and Titanium Hybrid models (the latter two options will be late availability).
