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).

Ford's Explorer-based Police Interceptor to get 365-hp EcoBoost option

Speeders beware, the police are going to be getting quite a bit faster. Ford has just announced that it will be offering its 3.5-liter, twin-turbocharged, EcoBoost V6 in the Explorer Police Interceptor. The new engine will be joining the existing 3.7-liter V6. The 365-horsepower, 350-pound-foot mill should be familiar to consumers as the powerplant that's found in the Ford Taurus SHO (and its LEO equivalent, the Taurus Police Interceptor) and the Ford Explorer Sport. It should also provide quite a kick in the pants to officers used to the naturally aspirated 3.7 and its 304 ponies and 279 pound-feet of torque.
The move to the more potent powerplant was born out of all the equipment officers need to carry on a day-to-day basis. These days, there's so much stuff that police need on a regular basis, that there's a genuine market for a faster Police Interceptor Utility, as it's known officially. The Explorer-based cruiser has already accounted for 68 percent of Ford's LEO sales in 2013, and that's with just the 3.7, and we'd only expect that number to increase once the twin-turbo, 3.5-liter V6 is available. Ford won't offer up any indication of what the take rate will be on the new engine, but we're guessing it'll be fairly high.
The success of the Explorer PI couldn't have come at a better time for Ford. The decision to end Crown Victoria production was not a popular one with police, and combined with Chevrolet and Dodge diving into the LEO market feet first, Ford hasn't been performing as well as it's wanted to. The Explorer has been helping it turn around, though. And with the inclusion of the EcoBoost, Ford also has a legit competitor for the Chevrolet Tahoe on the big utility side of the police market.

Forza Horizon G-Shock Car Pack brings Nissan IDx, Subaru Brat [w/video]

With winter's icy grip around much of the nation, now may be the perfect time to sit inside at night and enjoy some video games. The latest six-car G-Shock pack for Forza Horizon 2 on the Xbox One is now here, and it gives players a very eclectic group of vehicles to race around the game's open world. This month's group of vehicles spans the decades ranging from 2015 back to 1953. The newest and only concept of the group is the 2015 Nissan IDX Nismo. Since the production chances for this retro coupe look increasingly slim, this game might be your only chance to get behind the concept's wheel. However, if you prefer driving something a bit more classic and Italian, the 1953 Ferrari 500 Mondial is available. To add one more flavor of performance, there is the 2010 Mazda Mazdasped 3 hot hatch, which is also this month's free car for download. In addition to three takes on the sports car, Turn 10 is also offering a trio of off-roaders. The quirkiest among them is the 1980 Subaru Brat GL, which features two jump seats in the back to avoid the dreaded chicken tax. If you prefer something more boxy and American, then the 1975 Ford Bronco is sure to please. Finally, for some real power to get through the mud, there's the 2013 Ford F-150 SVT Raptor as tuned by Shelby with a supercharged 6.2-liter V8 making 575 horsepower. As usual, the whole pack costs players $5 to download, or it's free as part of the season pass. Scroll down for a brief video showing all of these virtual rides off and read the press release about them from Turn 10 Studios. This content is hosted by a third party.
