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: 1973 Mercury Marquis Brougham 4-Door Pillared Hardtop

Ford's Mercury Division debuted the Marquis in the 1967 model year, as a sporty coupe based on a stretched Ford LTD chassis. When the LTD got an update for 1969, so did the Marquis, and production of that generation of the top-of-the-line Mercury continued through 1978 (the Grand Marquis hit streets the following year). The 1969-1978 Marquis was a big, imposing land yacht, and the Brougham version came absolutely loaded with affordable luxury. Today's Junkyard Gem is a Marquis Brougham from the first year of the Malaise Era, found in a Phoenix self-service car graveyard recently. This car appears to have spent decades sitting outdoors in one of the harshest climates in the country, and so it's in rough shape. The vinyl top received the full thermonuclear treatment and is mostly obliterated by now. The interior got thoroughly cooked as well. Still, its original opulence shines through if you use some imagination. What hurts is that this car was packed with most of the good options, including the mighty 460-cubic-inch (7.5-liter) V8 engine with four-barrel carburetor. The price for the 460 was just $76 in this car, or around $548 in today's money. The base engine was a 429 (7.0-liter). Power numbers were way down for 1973 when compared to a couple of years earlier, partly as the result of tightening emissions standards but mostly due to the switch from gross to net power ratings that began midway during 1971 and was completed by the end of 1972. This engine was rated at 202 horsepower and 330 pound-feet. The only transmission available was a three-speed automatic. We can assume that the original buyer of this car and its single-digit fuel economy had a rough time when the OPEC oil embargo hit in the fall of 1973. Believe it or not, air conditioning was not standard equipment on the '73 Marquis Brougham (you had to move up to a Lincoln for that). This one even has the automatic temperature control feature, adding a total of $508 to the cost of this car (about $3,661 in 2023 dollars). That AM/FM/8-track radio—or, in fact, any radio—was an extra-cost option as well, with a price tag of $363 ($2,616 after inflation). The MSRP for the 1973 Marquis Brougham sedan (known as a "pillared hardtop" thanks to the frameless window glass) was $5,072, which comes to $36,555 in today's dollars. Obviously, its out-the-door cost would have been much higher with all the options.

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.
