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).

NHTSA closes Ford F-Series Super Duty steering probe without recall

The National Highway Traffic Safety Administration's investigation into 2008 Ford F-250 and F-350 Super Duty pickups, which was originally opened last year, has now ended without a recall. NHTSA was looking into steering failures on some 336,000 trucks.
The issue rested with the steering gear - NHTSA received five complaints of failures - which was redesigned in 2005. According to the report on the matter, investigators "found evidence of broken sector shaft gear teeth and piston damage consistent with incidents of single event overload."
NHTSA investigators, however, "found no evidence of fatigue or material property defects in any of the fractures. Analysis of complaint rates by vehicle build month showed no patterns indicating potential manufacturing quality issues and no difference before and after Ford introduced design changes to the input shaft and sector shaft seals in July 2007 to address potential leak concerns," according to the report, obtained by The Detroit News.

And the Top Gear UK Cars of the Year for 2013 are...

Those loony Brits at Top Gear have named their Car of the Year, and if you're thinking it's the McLaren P1, Jaguar F-Type, Land Rover Range Rover Sport or Rolls-Royce Wraith, we're sorry to inform you that none of those Anglo automobiles earned the crown. In fact, the winner of Top Gear's most prestigious award is quite the surprise.
Of course, those cars weren't without their own awards. The P1 was the top hypercar (sorry, Porsche 918 and Ferrari LaFerrari), while the F-Type netted best convertible and the Range Rover Sport was voted SUV of the Year. Other honorable mentions included the Mercedes-Benz SLS AMG Black and S-Class, the Porsche 911 GT3, the BMW i3 and the Ferrari 458 Speciale. The winner, though, wasn't even a high-dollar supercar. It was the Ford Fiesta ST.
Yes, the Fiesta ST beat out some off-the-wall cars like the revolutionary Volkswagen XL1 and the bonkers Peugeot 208 T16 Pikes Peak, not to mention all the cars we listed above, to take the title of Top Gear Car of the Year. And if you've driven one, you'll completely understand why.
