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.

2015 Ford Focus Electric hides in plain sight

The styling changes to the 2015 Ford Focus were shown off at the recent Geneva Motor Show, so what the EV version looks like is not that much of a surprise. Still, the 2015 Focus Electric is making its world debut here at the New York Auto Show, so we wanted to know what changes we are looking at compared to both the internal combustion engine version and the earlier EV models.
The exterior visual distinctions between the ICE and EV are minimal, and basically nonexistent from the A-pillar to the rear. Up front, you can see the charge port, of course, but the front fascia has also undergone a bit of an adjustment. The front doesn't have the ICE version's flattened grille and the EV's Ford logo creates a bump in the hood line where none exists on the ICE. The 2015's grille is also different than the one on the 2014 Focus Electric, being slightly smaller (you can see this better if you compare pictures in our new gallery above to these of the 2011 Focus Electric and these of the gas-powered 2015 Focus).
The updated 2015 interior - which we couldn't access ourselves - has things like a new center stack, improved cupholders and is basically identical between the gas and electric models. With the car off, you can't even tell if you're in an EV or ICE, Seema Bardwaj, the US brand manager for the Focus, told AutoblogGreen. The only things that are different, she said, are extra menu screens to show EV powertrain information to the driver.

2015 Ford Mustang invades SEMA, led by King Cobra

Ford showcased more than a dozen customized 2015 Mustangs at its sprawling 20,000-square foot display this week at the Las Vegas Convention Center as the iconic pony car's 50th anniversary celebration continued at the SEMA Show.
While Mustangs are always a hot commodity at SEMA, the new generation brought increased attention from the aftermarket, as builders like Galpin Auto Sports, Richard Petty's Garage and Vaughn Gittin Jr. offered their takes on the new 'Stang.
The extensive display included a range of Mustangs from mild to wild, with everything from a 600-plus horsepower King Cobra pictured at the top, to paint-and-wheel packages. The new regal Cobra, which we spied early in our SEMA adventure this year, may not be the replacement for the Cobra Jet as we speculated, but it does seem to point the way forward for the next iteration of a supreme Ford dragster. Fat drag slicks out back make it's reason for being abundantly clear, and for tells us that modded car is good for a 10.97-second quarter-mile run.
