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.

Subaru Legacy pitted against Roadkill project cars

There's an evergreen debate among auto enthusiasts about whether they would prefer to have the latest and greatest car of today or a certified classic from yesteryear. What if you had to further define that, though, and the choice was between a brand new 2015 Subaru Legacy or a turbocharged Datsun 240Z with a hatch that wouldn't close? Roadkill aimed to find out that and more in one of its best videos to date.
According to the hosts, Subaru came to them, handed over some money and challenged Roadkill's project cars against its latest Legacy. The result is every bit as good (or better) than any automotive-themed show you could find on television.
Things start simple with a figure-eight race in a rodeo arena with the Subaru taking on Roadkill's 1968 Ford Ranchero, originally built for ice racing. From there the Legacy races a 1968 Dodge Charger with no windows around and off-road rally stage. Finally, the Subie goes head-to-head against the Rotsun, the aforementioned turbocharged 240Z, through an abandoned neighborhood. Plus, there's a bonus drag race challenging them all.

FBI investigating recently fired Ford engineer for espionage

Agents of the FBI are investigating a potential case of industrial espionage involving a recently fired Ford employee. The Dearborn, MI-based manufacturer had its world headquarters searched by FBI agents on July 11, and according to The Detroit News, had warrants to seize recording devices handed over to Ford by Sharon Leach, a now-former Ford engineer.
Leach, who had spent 17 years with the Blue Oval, was fired last month, after Ford Security relieved her of eight Sansa listening devices. The FBI got involved shortly after her dismissal, searching her home on June 20 and seizing some two dozen items, including computers, jump drives and financial records, according to warrants obtained by The News.
Ford has remained quiet on the matter, with spokeswoman Susan Krusel confirming that the automaker was working with the FBI as part of a "joint investigation," while declining to provide any additional details.
