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.

NHTSA upgrades Ford floor mat unintended acceleration probe

According to a Bloomberg report, the National Highway Traffic Safety Administration has upgraded an investigation into complaints of unintended acceleration lodged against Ford vehicles. The investigation began in June of 2010 when just three complaints had been received and it only concerned the Ford Fusion and Mercury Milan, but this was at a time when the phrase "unintended acceleration" made grown men go pale. With 49 additional complaints received since then, the investigation has been reclassified as an engineering analysis - the last phase before a recall - and it has been expanded to include the Lincoln MKZ, making for a total of "around 480,000" units affected between the three sedans from the 2008 to 2010 model years.
The ostensible cause is that floor mats are trapping the accelerator pedal, but according to a Ford statement at the time, the entrapment is due to owners placing the optional all-weather floor mats, or aftermarket floor mats, on top of the car's standard floor mats. NHTSA has backed up that assessment, pinning the blame on "unsecured or double stacked floor mats."
On the face of it, it would appear that NHTSA has upgraded the status not because of Ford's error, but owner error, and Ford has stated publicly that it is "disappointed" in NHTSA's move. On top of NHTSA still being skittish after that other unintended acceleration debacle, it could be seen to be taking its time investigating all of the variables: it's reported that Ford changed its accelerator pedal design in 2010, a "heel blocker" in the floorpan has been considered a potential culprit in how the floor mats could be trapping the pedal, some drivers have said the floor mats weren't anywhere near the pedal, and according to a report in the LA Times, in "a letter sent by Ford to NHTSA in August 2010, the automaker said it found three injuries and one fatality that 'may have resulted from the alleged defect.'"

Ford Focus Electric gets $6,000 price drop, now starts at $29,995

In early 2013, the Nissan Leaf shed a massive $6,500 from its $35,200 base price to offer a new starting price of $28,800. Since then, we have seen numerous other plug-in vehicles get smaller price tags, from the Honda Fit EV (lower lease price) to the Chevrolet Volt (around $5,000 lower) to the Mitsubishi i (a $6,130 drop). Last year, Ford lowered the $39,200 price of the Focus Electric by around $4,000, but that hasn't been enough to get the Ford EV to really compete, saleswise, with other plug-in vehicles on the market. But wait, as they say, there's more. This past weekend, Ford lopped another $6,000 from the price of both the 2014 model year Focus EVs currently on dealer lots as well as the redesigned 2015 models that are now rolling out (they're basically the same car, minus some appearance changes). Ford spokesman Aaron Miller confirmed to AutoblogGreen that the Focus EV will now start at $29,995 and said that reducing the price should make the Blue Oval's only pure EV competitive. "We hope by reducing the price we're giving consumers another reason to consider it," he said. Through the end of September 2014, Ford has sold just 1,534 Focus EVs in the US (the model sold 1,335 in the first nine months of 2013). For comparison's sake, the Nissan Leaf starts at $29,010 and sells around 3,000 units a month in the US. Miller notes that the Focus EV has been selling the best on the West Coast, and is also doing well on the East Coast. After that, he said Atlanta and the Great Lakes area also see decent sales of model's admittedly small pie. We can only assume that offering the EV for under $30,000 will make that pie somewhat bigger.
