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).

GM already raising prices on 2014 Silverado and Sierra pickups

General Motors must be pretty pleased with sales of its two newest pickups, the GMC Sierra and Chevrolet Silverado, as it's announced price hikes for both models, as part of a planned price tweak.
Prices will be bumped by as much as $1,500, although weirdly, they'll be offset by as much as $1,500 in cash-back offers through the end of October. Fox Business reports that GM spokesman Jim Cain said of the price hike, "With the sell down of the '13 models nearly complete, this price adjustment was planned and is a normal part of business."
The move, as Fox is quick to point out, is an interesting one, as sales of the twin pickups struggled last month relative to the Ford F-Series, while both of GM's crosstown competitors have been aggressively undercutting Silverado and Sierra prices. The F-150 starts at $24,070 and the Ram 1500 comes in at $23,600, not counting any cash on the hood. A base Silverado, meanwhile, retails at $25,575.

Carfection looks for the ultimate pocket rocket

If there's one thing we love, it's a good showdown. Especially when it's on video, done by some Englishmen, and involving some manner of performance machinery. Like this latest clip, for example, from Carfection. The team formerly known as Xcar have assembled three very compelling supermini hot hatches: two we can get on our side of the pond, and one we can't. One American, one Frenchman, and one Brit. One cheap, one expensive, and one somewhere in between. They all pack turbo fours, of course, but placed in entirely different packages. There's the evergreen favorite Ford Fiesta ST, the Renault Clio RS 220 Trophy that should have the rest licked, and the retro rocket that is the Mini JCW. And there's only one way to find out which is the best. It's a tough contest, to be sure, but lest you think it all comes down to specifications or which one's the newest, you'll want to think again. Because when it comes to hot hatches, all the electronic gizmos and power boosts in the world can't show up a perfectly dialed-in chassis that lets you hug the curves and feel like you're going a lot faster than you actually are. But don't take our word for it – see what our British friends have to say about it in the Queen's English in the seventeen-minute clip above. Related Video:
