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.

Watch NASCAR racer Brad Keselowski do a burnout... in a hotel conference room

A vast majority of hotels frown upon smoking inside the building these days, but Brad Keselowski doesn't follow the rules. During his introduction at the 2013 MiilerCoors Distribution Convention, the reigning NASCAR Sprint Cup champion smoked the tires of his Miller-sponsored Ford Fusion stock car, adding a pair of thick, black stripes to the carpeting of the Marriott World Center's conference room.
This definitely isn't a high-quality video, but it's the perfect vantage point to watch Keselowski lay down some rubber and receive a well-deserved standing ovation after pulling up in front of the crowd. Check out the short-but-sweet video posted below.

Ford Australia pulls the ol' talking car prank

Siri from Apple has proven that being able to talk to your technology doesn't always work perfectly. But what if it could eventually go far enough to give a personality to inanimate objects like our cars? Ford took just this path to comedic effect by playing a prank on many unsuspecting Australians, in a new commercial for its EcoSport compact crossover.
The Aussies seem very nonchalant about having a random parked car talk to them, and they seem surprisingly game when it asks them to get in, call a celebrity and tell a joke. (We're guessing there are some hilarious outtakes, too.) Scroll down to watch some folks from Down Under have a conversation with Ford's CUV.
