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).

Hennessey Ford GT sets 267.6-MPH record at Texas Mile [w/videos]

The record-setting Hennessey-powered camouflage Ford GT we showed you at this time last year headed back to the Texas Mile and managed to bring home yet another record. As you may recollect, last year saw Mark Heidraker's machine sprint to a record 257.7 mph thanks to propulsion from its twin-turbo 5.7-liter V8. The big mill sucks down race gas, and this year the creation pulled off a 267.6-mph run over the weekend. That feat set a new record for the event. Something tells us neither Heidraker nor Hennessey are done squeezing more thrust from this machine.
This particular Ford GT has already gone through a number of permutations. Hennessey started by tweaking the factory supercharger set up before abandoning the blower in favor of two turbos. Since then, the crew has poked and prodded it to coerce as much grunt as possible out of the car. We expect Hennessey will probably come out with a video of the record-setting run shortly, but in the meantime, you can see a couple of videos of the car's runs in Texas below (one of which actually captures the record run). Enjoy.

2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:
