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 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.

Junkyard Gem: 1971 Mercury Comet 2-Door Sedan

When Ford introduced the original Maverick for the 1970 model year, Dearborn tradition required that a Mercury-badged version be created. That car ended up being the Comet, built from the 1971 through 1977 model years. Here's one of those first-year Comets in rough but recognizable condition, found in a Denver self-service yard not long ago. The Comet name had spent the 1960s affixed to the flanks of Mercurized Ford Falcons (1960-1965) and Fairlanes (1966-1969). Since the Maverick was the successor of the Falcon — sales of which went into an irrecoverable downward spiral once its sportier Mustang first cousin hit the streets — it made sense to move the Comet name over to the Mercury version. Nearly every American Mercury model ever sold was a U.S.-market Ford model with a different name and some gingerbread slapped on. Notable exceptions to this tradition include the 1999-2002 Mercury Cougar (mechanically based on the Contour but with a unique body) and the 1991-1994 Mercury Capri (an Australian-built mashup of Mazda components borrowed from the Ford Laser). The Comet was by far the cheapest Mercury model available in 1971, though it was considered more prestigious than its Maverick counterpart. The price tag on the '71 Comet two-door sedan started at $2,217 (about $16,505 in 2022 dollars), while the '71 Maverick two-door sedan cost $2,175 ($16,193 today). Meanwhile, AMC would sell you a new Hornet two-door sedan for one dollar less than a Maverick, Chevrolet had the Nova coupe for a dollar more than the Maverick, and Plymouth offered the Valiant Duster for $2,313 ($17,220 now). Toyota had a Maverick competitor as well that year, with the Corona at $2,150 for the sedan and $2,310 for the coupe. Having driven every one of the aforementioned models, I'd take the Duster if I went back in time and had to choose one (as a 1969 Corona owner, I'm not a fan of the 1971 facelift, though the Corona's build quality beats the Duster's). The build sticker on this car tells us that it was built at the Kansas City Assembly Plant (where Transits and F-150s are made today) and sold through the Los Angeles district sales office (there was a DSO in Denver, so it's a near-certainty that this car didn't start out in Colorado). The paint started out as Bright Blue Metallic (it's neither bright nor metallic 51 years down the road) and the interior was done up in Medium Blue Cloth & Vinyl.
