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.

Vile Gossip | Adventures in tire testing

Jean Jennings has been writing about cars for more than 30 years, after stints as a taxicab driver and as a mechanic in the Chrysler Proving Grounds Impact Lab. She was a staff writer at Car and Driver magazine, the first executive editor and former president and editor-in-chief of Automobile Magazine , the founder of the blog Jean Knows Cars and former automotive correspondent for Good Morning America . She has lifetime awards from both the Motor Press Guild and the New England Motor Press Association. This is her first column for Autoblog — look for more Vile Gossip in the future. I began writing at Car and Driver magazine back in its golden age in the 1970s, before I'd actually read it. I knew very little about cars. The only magazine I read religiously was Four Wheeler because I owned big trucks and liked to go off-roading with my Chrysler Proving Grounds friends. My vast 10 years of driving experience up to that point (high-speed dirt-road idiot, taxicab driver, Chrysler Proving Grounds test driver) had less bearing on my being hired at Car and Driver than the fact that the editor just wanted to rile up the all-male staff. He didn't need me for that. They were already in full dudgeon when I arrived. They'd just spent a chunk of time testing a stack of tires for their big tire-test issue, and the editor-in-chief was toe-to-toe with the technical editor over the rankings of the top 10 tires. It was loud, and it was angry. I had no idea that car magazines tested tires. Cab driving had led me to believe that airing up a tire and changing a flat was all you needed to know. I changed so many flats on that cab, I eventually wound up in front of a live audience on the " Oprah Winfrey Show" demonstrating my brilliance with a jack and a tire iron. My point, of course, is that tires are more controversial, and also more essential, than you'd think. My other point is that it's good to get worked up about the subject, but not quite so good to let yourself be seen, as I did, on my hands and knees with my ass up in the air on national TV. This is how I prefer to test a tire: First, pick a top brand. Then accept their invitation to try and beat the crap out of their tire. I chose Yokohama, celebrating its 100th anniversary this year. The big news for them was the GEOLANDER M/T G003!

2015 Ford Mustang vs. Camaro and Challenger [w/poll]

The horsepower wars are tightening among the Detroit Three, as the Ford Mustang, Chevrolet Camaro and Dodge Challenger are getting bigger, more powerful, and yes, more fuel efficient.
That came into sharper focus this week as more information was revealed about the most insane Challenger ever - the 707-horsepower Hellcat - followed quickly by Ford's in-depth showcase of the 2015 Mustang in Dearborn.
It's shaping up to be a golden age for enthusiasts, and what's under the hood is becoming more important than ever.
