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 Australia launches Falcon GT F 351, last of its line [w/video]

It's always best to go out with a bang rather than a whimper, and Ford Performance Vehicles is doing just that in Australia with the Falcon GT F 351. It's the most powerful road car the Aussie performance brand has ever made with a supercharged 5.0-liter V8 pumping out 471 horsepower (351 kilowatts) and 420 pound-feet of torque. It's joined by the FPV Pursuit Ute with the same powerplant tuned to 422 hp and 402 lb-ft. Sadly, the last F in this Falcon's name stands for Final.
The GT F 351 is a monumental way to go out, though. It harkens back to the old days of Aussie muscle Fords, and the 351kw output is meant to reference the classic Falcon GT and its 351-cubic-inch V8. In addition to the massive power, the F has the improved suspension from the R-Spec model and Brembo brake calipers.
FPV is building just 500 GT F sedans for Australia and 50 more for New Zealand, plus 120 Pursuit Utes. They feature a blacked-out hood and black stripes over the hood and sides, plus gloss black accents around the headlights, door handles and mirrors.

Jay Leno sees how the other half lives with CHP cop cars new and old

Comedian Jay Leno is changing gears from driving fast cars to checking out some of the police cruisers that regularly chase down and dish out punishment to those fast cars. In this episode of Jay Leno's Garage, we get the lowdown on the modifications made to the Ford Explorer for the Interceptor package (which looks pretty tough in its California Highway Patrol livery).
The new Ford is cool, but cooler still are the pack of classic CHP cars that Jay has along for the episode. A 1982 Mustang, 1966 Dodge Polara, 1970 Mercury Monterey and 2000 Crown Victoria are all in the shop. Better still, Jay lays out an argument for ones of the classic cruisers as the best cop car of all time. Get your guesses in now, and then scroll down to watch and learn.
