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.

Ladies Love It: Ford Fiesta wins Womens World Car of the Year

It's official: A panel of female automotive writers has chosen the Ford Fiesta 1.0-liter EcoBoost as the Womens World Car of the Year, and it beat tough competition like the Mazda CX-5, Range Rover and Porsche Boxster S for the overall top spot.
The CX-5 and Range Rover won the SUV and Luxury Car categories, respectively, and the Boxster S laid claim to the Sports Car category, beating the runner up Audi RS5 and third place Toyota GT86/Subaru BRZ (or Scion FR-S). The Audi Allroad was named the Family car of the year.
The panel consisted of 18 female automotive writers from around the world tasked with picking the best car in each of eight categories, including top vehicle overall, using criteria that women utilize when shopping for a car. That includes safety, value-for-money, aesthetic appearance, storage space, child-friendliness, ease-of-driving, color, sex appeal and environmental footprint.

2015 Ford Mustang [w/videos]

It'd be unwise to bet against the sixth generation of this legendary nameplate.
The 2015 Ford Mustang is assuredly the most anticipated new vehicle of the year. The redesigned Pony Car has been the subject of frantic gossiping and covert spy photos covering everything from the way it looks to the tech it will include, its performance, mechanicals and a bevy of other aspects of Ford's performance icon.
