Automakers' rush on aluminum may result in shortage

Aluminum is the new buzzword in the automotive industry. The latest Range Rover and Range Rover Sport both take advantage of the lightweight material to shave huge amounts of body fat (only it's called "aluminium" over there). Audi and Jaguar have been using the stuff for years in their A8 and XJ, respectively, and now, aluminum is going mainstream, arriving on the 2015 Ford F-150.
While we're excited to see aluminum make an impact outside the premium market, its widespread adoption apparently won't come without some problems, notably in terms of supply. "There isn't an automotive manufacturer that makes vehicles in North America that we're not talking to," Tom Boney, of Novelis, the largest global supplier of aluminum sheetmetal, told The Detroit News.
According to Boney, Ford's use of aluminum on such a large scale has forced auto manufacturers in "every boardroom" to reconsider their plans following the F-150's unveiling, for one simple reason: there's not exactly enough aluminum to go around, at least in the short term. The auto industry presently only accounts for six percent of the aluminum sheet produced, but as the material is adopted by more and more brands, that figure is expected to swell to 25 percent within the next six years.

Mulally to stay at Ford through end of 2014 at least

Alan Mulally isn't going anywhere... at least not just yet. The CEO who helped turn around Ford Motor Company has been linked to the top job at tech behemoth Microsoft, leading to a flurry of rumors about potential successors. Those rumors, though, may have just been put to rest - at least for a little while.
Speaking to Edsel Ford II (great-grandson of company founder Henry Ford) at the unveiling of the new Mustang, Automotive News Europe confirmed that Mulally would stick around until the end of next year. "Alan is staying through the end of 2014 and that's all I know," said Ford. "Frankly, he has told us that his plan is to stay with Ford through the end of 2014."
Presuming that Edsel Ford is correct and that Microsoft isn't so hot on Mulally that it saves the position for him, it seems increasingly likely that the 68-year-old exec is more interested in continuing to work in Dearborn rather than in Redmond.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.
