NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.

Junkyard Gem: 1955 Mercury Montclair Coupe

I find plenty of 1950s Detroit vehicles in the big self-service car graveyards I frequent, but most of them are fairly ordinary sedans that never stood much chance of getting fixed up and put back on the road. Such is not the case with today's Junkyard Gem, which is a top-trim-level, heavily optioned hardtop coupe from one of the most desirable model years of the tailfins-and-chrome postwar era. Nearly every Mercury model ever made was a Ford model with some cosmetic changes applied, and the '55s looked very similar to their mechanically identical Ford brethren. In 1955, the new Mercury came in three trim levels: the entry-level Custom, the medium-zoot Monterey, and the glitzy Montclair. Each was available as a hardtop coupe and four-door sedan, with wagon versions of the Custom and Monterey. The Montclair could be purchased as a convertible or with the wild "Sun Valley" glass roof. The Montclair got its own line of hallucinogenic two-tone interiors, in order to make the daily lives of Europeans feel even more gray and penurious (the UK only dropped food rationing in 1954, and the two Germanies were still clearing the rubble of their blown-up cities). This car's upholstery has been bleached by decades of sitting outside in the harsh High Plains climate, but it started out as vivid red and white "Chromatex" fabric. The list price on this car was $2,631, or about $29,200 in 2022 dollars. The Sun Valley and convertible Montclair each cost $2,712 ($30,100 today). Ford didn't offer a corresponding hardtop coupe in 1955, though the Fairlane Crown Victoria two-door did look extremely snazzy (and cost a mere $2,302— $25,545 now— with the same V8 engine as the Monterey). Meanwhile, Oldsmobile offered the handsome 88 Super Holiday Coupe for $2,714, though the Montclair had the more powerful engine. Oldsmobile had been selling new cars with overhead-valve V8s since the 1949 model year, while Ford didn't ditch the Model A-era flathead V8 for new U.S.-market cars until the 1954 model year (you could buy a new Simca Esplanada in Brazil with an Ardun-headed Ford V8-60 all the way until 1969). GM's Chevrolet Division got all the press in 1955 with the introduction of the brand-new small-block V8 engine, but Ford's 292-cubic-inch (4.8-liter) Y-Block V8 made more power than the 265-cube (4.3-liter) Chevy and the 324ci Olds Rocket 88.

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.
