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).

Shelby GT500 laps N"urburgring in under 7:40?

A couple of weeks ago we brought you footage and official times of the new Chevy Camaro Z/28 lapping the Nürburgring. With a 7:37.47 lap time, the Z/28 emerged as the fastest muscle car ever to lap the circuit. But what was missing from that picture was how fast the king of all Mustangs, the Shelby GT500, could manage to lap the Nordschleife.
Ford never released any information or footage of the GT500 on the Nürburgring that we were aware of - that is, until the guys at SVTPerformance.com put in a request for Mustang videos. Among the clips they received was never-seen, in-car footage of the Shelby GT500 lapping the circuit. And boy did it hustle.
Although not quite official, the video seems to show the GT500 lapped the venerated German track in a touch under 7:40. That would make it a tick or two faster than the Camaro ZL1 - but what of the Z/28? By Chevy's quoted time, the Z/28 is still faster than the GT500, but SVTPerformance suggests GM may have fudged the numbers a bit and scrubbed half a second or so off their lap time.

First Ford Mustang prototype shots caught by legendary spy shooter Jim Dunne

You know how people refer to someone as having "been around the block" to mean they're very experienced? Well, when it comes to automotive spy photography, Jim Dunne actually laid down the concrete slabs of the block's sidewalk. The unforgettable Dunne more or less invented the car spy game - a fact he cemented by writing book called Car Spy - and has been delivering spy shots and reporting on the industry for some 45 years now. (He also once employed this writer as his impromptu personal chauffer on a Volkswagen trip in Germany, while he slept, but that's a story for a different time.)
In any event, Dunne must be on a mission to prove that "elder statesman" doesn't also mean "washed up" as it is his shots of the upcoming new 2014 Ford Mustang that we've been handed by our friends at KGP Photography.
Mr. Dunne has likely spent the last few years obtaining powerful telescopic lenses, as the Ford in question has clearly been photographed from some distance. Nevertheless, what you see here is visual evidence that the sixth-generation Mustang has moved beyond the mule stage, and is now testing in proper prototype form. Sources indicate that there are production-spec body panels under that baggy canvass dress; but the slightly less bulky silhouette of the new car can be just made out. While the car's bumpers have been removed to obfuscate things, we can tell by way of the camo's apertures that the car's taillights have moved upwards and towards the lip of the tail. A fender vent appears to be visible, too, just behind the front wheel.
