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.

Ford Fusion demand outstripping supply

The attractive new 2013 Ford Fusion has done wonders for the brand in the highly competitive midsize sedan segment - the vehicle is up nearly 22 percent compared to last year. But that sales momentum may soon hold steady due to low inventory levels of the new Fusion across the United States.
According to a report in The Detroit News, citing automotive data and Ward's Auto, Ford currently has a 39-day supply of the Fusion. That might sound fine, but a normally healthy average is about a 60-day supply. If Ford were to stop production on the Fusion today, there would only be enough vehicles available to get through another five weeks of sales, according to the News.
Currently, Ford produces the Fusion at its three-shift assembly plant in Hermosillo, Mexico, and will add production at its facility in Flat Rock, MI later this year. A Ford spokesperson told The Detroit News that when Flat Rock production comes online, the automaker will need to rush new stock out to the regions with the most demand for the Fusion. Ford has doubled its coastal retail market share, with huge amounts of growth in areas like Los Angeles, San Francisco and Miami, the News reports.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
