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 board pushing Mulally for decision amidst fears story is drowning out other news

Automakers and their executives rarely like to divulge information regarding future goings on, but the board of directors at Ford sound like they're getting a little antsy about chief executive officer Alan Mulally and his plans for 2014.
According to Reuters, as news of Mulally's possible departure to Microsoft continues to swirl, Ford's board is looking to push the affable executive to make a decision about his future sooner rather than later. Apparently, the board is growing concerned that this will-he/won't-he drama may end up distracting the media from covering Ford's other big news events next year - items like the debut of key all-new products like the Mustang and F-150.
So far, the picture for Mulally's eventual successor remains fuzzy, but it's understood that the leading candidate remains the company's chief operating officer, Mark Fields. Just recently, we heard that Mulally will stay until the end of 2014, but a few months ago, Ford seemed open to the idea of him stepping down earlier than that.

And the Top Gear UK Cars of the Year for 2013 are...

Those loony Brits at Top Gear have named their Car of the Year, and if you're thinking it's the McLaren P1, Jaguar F-Type, Land Rover Range Rover Sport or Rolls-Royce Wraith, we're sorry to inform you that none of those Anglo automobiles earned the crown. In fact, the winner of Top Gear's most prestigious award is quite the surprise.
Of course, those cars weren't without their own awards. The P1 was the top hypercar (sorry, Porsche 918 and Ferrari LaFerrari), while the F-Type netted best convertible and the Range Rover Sport was voted SUV of the Year. Other honorable mentions included the Mercedes-Benz SLS AMG Black and S-Class, the Porsche 911 GT3, the BMW i3 and the Ferrari 458 Speciale. The winner, though, wasn't even a high-dollar supercar. It was the Ford Fiesta ST.
Yes, the Fiesta ST beat out some off-the-wall cars like the revolutionary Volkswagen XL1 and the bonkers Peugeot 208 T16 Pikes Peak, not to mention all the cars we listed above, to take the title of Top Gear Car of the Year. And if you've driven one, you'll completely understand why.
