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 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.

Autoblog Minute: New car customer satisfaction down according to latest ACSI report

Customers have spoken and automobile satisfaction is down in 2015. Autoblog's Chris McGraw reports on this edition of Autoblog Minute. Show full video transcript text [00:00:00] Customers have spoken and automobile satisfaction is down in 2015. I'm Chris McGraw and this is your Autoblog Minute. The American Customer Satisfaction Index or ACSI released its updated numbers and according to the survey, new car buyer satisfaction is down for the third straight year. According to an ACSI press release, customer satisfaction with new automobiles has fallen 3.7 percent, to 79 on its 100-point scale. The ACSI report is based on over 4,100 customer surveys collected in the second quarter of 2015 Sitting at the top of the industry in customer satisfaction is Toyota's Lexus brand with a score of 84. Which was good enough to dethrone Mercedes-Benz, which fell 3% to a score of 83. Of the Big Three, Ford was the only domestic automaker to maintain overall customer satisfaction with its score of 81. General Motors slipped 3% to 79 and Fiat Chrysler had a 5% drop, registering a score of 75 out the possible 100. What's driving this trend of customer dissatisfaction? ASCI points to the rise in recalls and car prices. Where do you land on customer satisfaction spectrum? Sound off in the comments with your thoughts on the current state of car ownership and brand quality. For Autoblog, I'm Chris McGraw.
