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.

Jerry Seinfeld doesn't love Sarah Jessica Parker's new Country Squire in latest CiCGC

Comedians in Cars Getting Coffee has finally returned for its fourth season of combining Jerry Seinfeld, a miscellaneous celebrity and a cup of java. But rather than fondly remembering some older piece of automotive machinery, this time around, Seinfeld is utterly unable to keep his hatred of Sarah Jessica Parker's 1976 Ford LTD Country Squire from coming out to hilarious effect.
However, Parker has such a high level of infectious enthusiasm for her recently purchased Country Squire that she seems to win over Seinfeld by the end - at least a little bit. For most of their time together, the two of them drive around Manhattan and the suburbs waxing nostalgic about what things were like when these wagons were ubiquitous.
Since this is actually SJP's car, she and Seinfeld trade off driving duties, and the image above should give you some indication of Seinfeld's reaction to the Sex and the City star behind the wheel. It seems this '70s land yacht might be a little too much for her to handle in New York traffic. Regardless, she is absolutely in love with her Ford.

Ford gives S-Max the Vignale treatment in Milan

Ford has a bit of a history in reviving the names of old coachbuilders it has long since gobbled up and using them to distinguish its top-of-the-line models in Europe. That's what it did for years with Ghia, and after having replaced it several years ago with the Titanium trim level, now it's doing it again with Vignale.
At the Frankfurt Motor Show last year, Ford revealed the Mondeo Vignale concept in both sedan and wagon body-styles, which are set to reach production next year. But before they do, the Blue Oval automaker is at it again, applying similar upgrades to the S-Max minivan and unveiling it in concept form in Milan this week.
Setting the Vignale concept apart from any other S-Max is its Milano Grigio rose-hued silver pearlescent paint, 21-inch alloys, chrome trim and hexagonal-pattern grille. Inside it's all ultra-soft quilted leather and aluminum trim, with tablet docking stations in the back and thinner, more flexible seats than the existing production version.
