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.

Ford will probably never offer two RS models at the same time

Autocar has some sour news for fans of go-fast Ford products. According to Roelant de Waard, Ford's president of marketing in Europe, the automaker will probably never offer more than one RS performance model for sale at the same time. That statement runs contrary earlier rumblings that suggested Ford would launch its next-generation Focus RS in 2015 and follow the hatch with a spate of other vehicles with an RS badge. But de Waard has made it clear that Ford of Europe is now focused on squarely on the next Mustang, even though there may be more RS models on the way eventually.
"What is clear is that the RS shouldn't be a series, or a car badge that we have in our portfolio all the time. It is an extreme car - something more than ST," he said.
That philosophy makes plenty of sense. We loved the old Focus RS - shown above in RS500 trim - because it was generally bonkers and plenty exclusive. Diluting either aspect is sure to end in disappointment for everyone involved.

Mustang driver proves wheels are overrated

We don't need to tell you that there's something missing in the image above. What we do need to tell you is that this is not a picture of a parked car stranded on the highway. This is, rather, just one frame from video of that three-wheeled Mustang traveling down the highway at highway-appropriate speed.
We don't know where you'd have to be nor how badly you'd have to be there to go shooting down the freeway in a car with three wheels, but if the New Daily News is correct, that place is somewhere in Texas. The video's short, but you'll have plenty of time to shake your head at it by just scrolling down.
