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: 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.

Junkyard Gem: 1972 Mercury Cougar XR-7

Starting with the 1939 model year and continuing through 2011, the rule in Dearborn was that most Ford models would get a dressed-up sibling wearing Mercury badges (and Canadians even got Mercury F-100s and Econolines). When the Mustang first hit showrooms in 1964, the countdown for a Mercurized version began. That car, the Cougar, debuted as a 1967 model marketed as "the man's car." Today's Junkyard Gem is a much-abused example of the early-1970s Cougar, found in a San Francisco Bay Area car graveyard a while back. Just as the Mustang packed on weight and price as the 1960s became the 1970s, the even more heavily gingerbreaded Cougar did the same. For 1971 through 1973, the Cougar was still based on the Mustang chassis but weighed several hundred additional pounds and was more than seven inches longer. The curb weight for this car was 3,298 pounds, versus 2,941 pounds for the lightest '72 Mustang coupe. Yes, there's a Mustang underneath all that chrome! When the Mustang went to a modified Pinto chassis starting in the 1974 model year, the Cougar moved over to the midsize Torino platform and stayed there until it rejoined the Mustang on the Fox platform for 1980 (though the honor of being the Mustang's near-twin went to the Mercury Capri at that point). For 1989, the Cougar became an MN12 Thunderbird sibling, where it remained through its 30th anniversary … and then the Cougar got the axe. The Cougar story wasn't done at that point, however, because the name got revived in 1999 with a Mondeo-based version that lasted through 2002 and bears the distinction of being one of the few Mercury models with no corresponding Ford-badged counterpart. Along the way, there were Cougar sedans and even station wagons, with the curb weight of the heaviest-ever Cougar bloating to well over two tons (the winner of that honor is the 1977 Cougar Villager wagon, scaling in at an astounding 4,482 pounds). In 1972, though, all new Cougars were coupes or convertibles, and all of them came with factory V8 power. The build tag on this one tells us that it was assembled at the River Rouge compound in Dearborn and sold via the Kansas City sales office. That tells us that someone drove this car to California after buying it in the Midwest; Ford also built 1972 Cougars in San Jose, so California Mercury shoppers would have bought locally-produced ones. It's a top-end XR-7 in Medium Bright Yellow paint, with the interior in Medium Ginger.
