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).

2014 Ford Cobra Jet announced with new colors, parachute mount

Ford's drag-strip-ready Mustang Cobra Jet is back for 2014, and it's sporting a few changes to make it even better - both in competition and while sitting still. Rolling off the assembly line ready for duty in the NHRA Stock or Super Stock classes, production of the 2014 Cobra Jet is limited to just 50 units.
Racing upgrades for 2014 include the addition of a new three-speed transmission and a parachute mount, and while these will make the car better in the quarter mile, the Cobra Jet's new colors will make it look better tearing down the track. Buyers can now get their racecars painted up in Gotta Have-It Green or a custom, Cobra Jet-exclusive matte black hue. Ford and Ford Racing have already teamed up to make this an incredible factory drag racer with a full rollcage, massive Hoosier slicks, a race-tuned suspension setup and a supercharged 5.0-liter V8. Now, if only wheelie bars came standard...
Unlike the confusing third-party ordering system announced for the COPO Camaro, all you need to snatch up a 2014 Cobra Jet is $97,990 and good timing (as the cars will be sold on a first-come, first-served basis). Ordering opens up next month with production commencing in July. Check out the press release below.

Has the auto industry hit peak hybrid?

Hybrids are known for their great fuel economy and low emissions, but it looks like given current market conditions, only about three percent of new car consumers are willing to pay the premium for them. A new study from IHS/Polk finds that the hybrid market share among overall US auto sales are falling, despite more models with the technology on sale than ever before.
The study examined new car registrations in March from 2009 through 2014. In that time, the auto industry grew from 24 to 47 hybrid models available to consumers, but market share for the powertrain remained almost stagnant in that time. As of 2009, hybrids held 2.4 percent of the market; it fell slightly to 2.3 percent in 2010 and grew to 3.3 percent in 2013. However, 2014 showed a drop back to 3 percent. Overall hybrid sales have been growing since 2010, but they just aren't keeping up with the total auto market.
According to IHS/Polk, this isn't what you would expect to see. Usually, each new model in the market brings along with it a boost in sales. The growth in hybrid models 2009 to 2014 should have shown a larger increase in share for the segment.
