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).

Why the Detroit Three should merge their engine operations

GM and FCA should consider a smaller merger that could still save them billions of dollars, and maybe lure Ford into the deal. Fiat-Chrysler CEO Sergio Marchionne would love to see his company merge with General Motors. But GM's board of directors essentially told him to go pound sand. So now what? The boardroom battle started when Mr. Marchionne published a study called Confessions of a Capital Junkie. In it, Sergio detailed the amount of capital the auto industry wastes every year with duplicate investments. And he documented how other industries provide superior returns. He's right, of course. Other industries earn much better returns on their invested capital. And there's a danger that one day the investors will turn their backs on the auto industry and look to other business sectors where they can make more money. But even with powerful arguments Marchionne couldn't convince GM to take over FCA. And while that fight may now be over, GM and FCA should consider a smaller merger that could still save them billions of dollars, and maybe lure Ford into the deal. No doubt this suggestion will send purists into convulsions, but so be it. The Detroit Three should seriously consider merging their powertrain operations, even though that's a sacrilege in an industry that still considers the engine the "heart" of the car. These automakers have built up considerable brand equity in some of their engines. But the vast majority of American car buyers could not tell you what kind of engine they have under the hood. More importantly, most car buyers really don't care what kind of engine or transmission they have as long as it's reliable, durable, and efficient. Combining that production would give the Detroit Three the kind of scale that no one else could match. There are exceptions, of course. Hardcore enthusiasts care deeply about the powertrains in their cars. So do most diesel, plug-in, and hybrid owners. But all of them account for maybe 15 percent of the car-buying public. So that means about 85 percent of car buyers don't care where their engine and transmission came from, just as they don't know or care who supplied the steel, who made the headlamps, or who delivered the seats on a just-in-time basis. It's immaterial to them. And that presents the automakers with an opportunity to achieve a staggering level of manufacturing scale. In the NAFTA market alone, GM, Ford, and FCA will build nearly nine million engines and nine million transmissions this year.

Shelby Mustang stars with Ethan Hawke, Selena Gomez in Getaway movie

Car movies. We keep watching them, they keep making them. Despite Fast & Furious 6 still blowing up the box office (No. 1 in theaters for the second straight week) and production on Transformers 4 being well underway (check out the Bugatti Veyron and Corvette Stingray as new cast members), there's still room on the marquee for more car movies. Next one up is an Ethan Hawke joint called Getaway, which prominently co-stars a Ford Shelby GT500. The first trailer for Getaway, which opens in theaters on August 30, was released yesterday and can be watched below.
The movie's plot centers around Hawke's character, former race car driver Brent Magna, who must somehow use this car, what appears to be a generation-old Shelby GT500 Super Snake he "commandeered," to save his wife. The movie's third co-star is Selena Gomez, whose character we're told is the owner of said Shelby. A 20-year-old having a car like this seems a bit far-fetched - especially in Europe - and on paper, this plot looks like it cribs liberally from Charlie Sheen's 1994 The Chase. But all we've got to go on is a brief plot description and the trailer below, so we'll withhold judgment until the studio firmly has our ticket money in its grasp.
The Shelby GT500 is, of course, no stranger to acting. Before this jump to celluloid, the most fearsome of all Mustang models starred in the return of Knight Rider to television on NBC back in 2008. That gig didn't pan out for the car, the show lasting only one season and 17 episodes. In fact, with its casting in Getaway, the Shelby GT500 is one of the few actors who escaped that debacle with a future in show biz.
