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).

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.

Revisiting the 2008-09 auto bailout that saved GM and Chrysler

The Federal Reserve stayed open late on December 31, 2008. There's almost no way you could remember that because barely anyone knew at the time. But General Motors had to pay its bills, and the Fed wired money so GM could still buy things in January. Without those funds, the nation's largest automaker wouldn't have seen much of 2009. It's one of many heart-stopping moments that illustrate just how close Detroit's Big Three came to extinction nearly a decade ago. They're chronicled in a new movie, Live Another Day, premiering in theaters September 16. Filmmakers Bill Burke and Didier Pietri interviewed nearly all of the key executives, federal officials, and union chiefs to recreate the auto industry's most perilous period. The movie begins in the aftermath of Lehman Brothers' demise amid the global financial meltdown. Things looked bleak for American carmakers, and their CEOs were laughed off Capitol Hill when they sought a Wall Street-style bailout. "It was a feeling that it was the end of the world," Pietri told Autoblog in an interview where he and Burke previewed the film. Saved by last-minute loans authorized by the Bush Administration after Congress refused to act, Detroit staggered into 2009 with a faint pulse. Live Another Day illustrates the downward spiral that played out that winter as President Obama and his task force – with little prior knowledge of the auto industry – wrestled over the fate of hundreds of thousands of jobs. GM's longtime CEO Rick Wagoner was fired in March. Fiat CEO Sergio Marchionne suddenly appeared as a savior for Chrysler, with his own motives. Obama rejected restructuring plans from the automakers. Chrysler declared bankruptcy on April 30. GM followed June 1. The sequence was very public, but Pietri and Burke showcase lesser-known events that shaped the outcome. They also seek to dispel the notion that the government rescued GM and Chrysler from incompetent leaders. "We never subscribed to the theories that the management structures of the companies were a bunch of idiots who didn't know what is going on," Pietri said. At one point, Chrysler executives were negotiating with Marchionne and Fiat. Unbeknownst to them, the government was having its own talks with the Italian automaker. The filmmakers also cast light on the bankruptcy process, which was shredded to shepherd two of America's industrial icons through reorganizations.
