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.

Generation Z prefers Ford, wants better fuel efficiency

Fear not the future, dear green-car enthusiast. For the youngest drivers like good gas mileage. And they don't really like SUVs or trucks. Breathe easier. About 80 percent of drivers ages 16 to 21, part of what's known as 'Generation Z,' prefer cars more than any other type of larger light-duty vehicle, with about half of that group preferring compact cars, The Detroit News says, citing data company MaritzCX. That company polled about 1,100 prospective young car buyers and found them to put a priority on fuel economy because that group is... well, cheap. To put that demographic's vehicle choice into perspective, just a third of light-duty vehicles sold in the US last year were cars, while the rest were SUVs and trucks. So the future is bright, and possibly devoid of some of the smog we're now seeing. Meanwhile, Ford is the most popular brand among younger drivers, again reflecting that company's more recent emphasis on hybrids, plug-ins and high-fuel-economy gas-burning engines. Ford's US green car sales fell 1.4 percent last year to about 86,500 units (falling C-Max Hybrid demand pulled the American automaker's numbers down), so we'd think that this is very welcome news for the Blue Oval.

2015 Ford C-Max gets a corporate nose job [w/video]

Ford might not have the splashiest booth here at the 2014 Paris Motor Show, but the automaker is showing off quite a bit of hardware that will actually end up on roads across Europe. Parisians are no doubt tickled at getting to see the specifications of the Mustang tuned for The Continent (which has a revised suspension for European roads, and a few visual nips and tucks), in addition to the revised face of the family-friendly C-Max.
As you can see, C-Max styling has been revisited with a deft touch, grafting Ford's six-sided corporate grille on the nose, in place of the outgoing car's two-part affair. New headlights can also be found on the car's revised front fascia, though the rear end of the C-Max looks only slightly different than the current version.
Inside the cabin, Ford has consolidated controls and upped the ante in terms of material quality, with "black satin" and chrome details and more storage capacity, overall. Grocery-lugging moms and dads everywhere should appreciate the hands-free liftgate feature, as well.
