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.

Ford Fiesta 1.0L EcoBoost sales robust in early going

Okay, okay, okay, so I was just a smidge wrong. Those that read my review of the Ford Fiesta with the new 1.0-liter, EcoBoost engine will know that while I really enjoyed the torquey little three-cylinder, I was concerned that Ford's decision to force 1.0-liter owners into a manual transmission, steel wheels and one trim level might hurt sales of the new engine. I was also concerned that the promised 45-mile-per-gallon highway rating wouldn't be enough to tempt buyers into trying an engine that's so far outside of what the general public is use to. My concerns, though, seem to have been for naught.
While not doing a booming business on the triple-equipped Fiesta, Ford is seeing a take rate of four to eight percent per month in the engine's first few months on sale. Now, four to eight percent might not sound like a lot - if, like last year, the Fiesta sells around 71,000 units, there'd be barely 5,600 1.0-liter models on the road. It is also small potatoes relative to the take rate on EcoBoost-equipped vehicles across the Ford range, which US sales analyst Erich Merkle estimates to be roughly 35 to 40 percent of retail sales. Still, according to The Detroit News, the 1.0-liter is getting adopted at roughly the same rate as the sparkling Fiesta ST, which should be a solid indication of just how well this little engine is doing.
The 1.0-liter's success "really speaks volumes, not just to what we're doing with the Fiesta, but with EcoBoost in general," Merkle told Autoblog.
