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.

Toyota, Ford and Honda again top Consumer Reports Car-Brand Perception Survey

Consumer Reports has released its annual Car-Brand Perception Survey, and the list looks awfully familiar. The top six brands are identical to last year's results, with Toyota, Ford and Honda continuing to occupy the podium. All told, Toyota walked away with 133 points, putting it 15 ahead of second-place Ford. Honda jumped 26 points this year, narrowing Ford's lead to just four points in total.
Consumer Reports polls buyers from across the country on how they see multiple brands in seven categories, including quality, safety, value, performance, design/style, technology/innovation and environmentally friendly/green. Researchers then combine the findings to come up with the total brand score.
While value and performance remain important to buyers, CR found quality and safety are still on top when it comes to significance. Scion and Mitsubishi found themselves at the bottom of the pack with the worst score of all, tied at just six points. Ram, Fiat and Mini filled out the lowest five with scores of seven, eight and 10 points, respectively. You can read the full press release below for more information, or head over to the Consumer Reports site.

2015 Ford Mustang revs it up at Cars & Coffee

Just because the new 2015 Ford Mustang has officially been released, you didn't think that would be the end of the matter - did you? Of course not. There'll still be plenty of rumors, reports and video footage to bring you. Like this, the first non-official footage of the new pony car in the wild.
Shot by YouTube user SotA1080 and dug up by our friends at CarBuzz, this clip shows the new Mustang posing for photos (alongside other Mustangs) and starting up its engine at the most recent gathering of Cars & Coffee in Irvine, CA. And this being the GT model, it's not packing the V6 or the turbo four, but the red-blooded 5.0-liter V8 that tells us and enthusiasts worldwide that the new Mustang has not lost its way. Scroll on down to watch the footage for yourself.
