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.

Are you a new Ford Mustang SVO? [w/video]

When Ford announced that its 2015 Mustang would arrive with a 2.3-liter EcoBoost four-cylinder engine, three letters came to mind: SVO. While Ford hasn't said a word regarding the rebirth of a Mustang SVO model, this latest set of spy shots shows us something very, very interesting. Allow us to explain.
The Mustang prototype in these photos looks very similar to the GT500 test cars we've spotted before - same bulging hood, aggressive front fascia and air vents aft of the front wheels. What's different, however, is around back. Have a look at the exhaust, and note that instead of the GT500's usual quad pipes, two of the exhaust outlets have been capped off.
Our spies point out that these exhaust outlets could be closed for some sort of emissions testing or another engineering reason, but it's also important to note that the engine and exhaust notes of this car sound completely different from earlier GT500 prototypes. We've got a video below that compares the two.

Consumer Reports explains its disdain for infotainment

One of the perks of reviewing all manner of cars and trucks is that we're exposed to all the different infotainment systems. Whether Cadillac's CUE, Chrysler's UConnect, BMW's iDrive or MyFord Touch, we sample each and every infotainment system on the market.
Not surprisingly, some are better than others. It seems consumers have come to a similar consensus, with Consumer Reports claiming that Ford and Lincoln, Cadillac and Honda offer the worst user infotainment experiences. Not surprisingly, you won't find much argument among the Autoblog staff.
Take a look below to see just what it is about the latest batch of infotainment systems that grinds CR's gears. After that, scroll down into Comments and let us know if you agree with the mag's views.
