Junkyard Gem: 1979 Mercury Marquis 2-Door Sedan

As the creator of the now-much-overused term "Malaise Era" (which I say started in 1973 and ended in 1983, full stop), I have a certain affection for the big two-door Detroit cars of the late 1970s. When such a car is built on the very first model year of Ford's long-lived Panther platform and I find one in a junkyard, I must document it. The 1979 Mercury Marquis is such a car, and this one was found in a San Francisco Bay Area self-service yard last month. Since Ford built the Grand Marquis all the way through the demise of the Panther platform— and Mercury itself— in 2011, it's easy for us to forget that the model name started out as just the plain old Marquis, back in the 1967 model year, with the Grand appellation used for the car's top trim level. While today's Junkyard Gem has some of the features of the Grand Marquis and Marquis Brougham trim levels for 1979 (notably the padded vinyl landau roof and power windows), it lacks the huge chrome lower-body moldings of those cars. Instead, it's a regular Marquis 2-door sedan with a big load of expensive options. That landau roof has suffered greatly from its decades beneath the vinyl-disintegrating California sun. The Panther platform was a big technological upgrade from the late-1950s-vintage chassis technology of full-sized Fords of the 1960s and 1970s, and it stayed in front-line service in much the same form through 2011. Though its ride and handling were much improved, the 1979 Marquis was quite a bit smaller than its predecessors, and that caused some grumbling among Mercury shoppers. Some ham-handed junkyard shoppers really tore up the interior of this car while extracting a few bits and pieces, but we can still admire the Pine Green pleather of the glorious Twin Comfort Lounge front seats. You had two engine choices when buying a new '79 Marquis: the base 302-cubic-inch (5.0-liter) Windsor V8 making 129 horsepower or the optional 351-cubic-inch (5.8-liter) Windsor V8 rated at 138 horsepower. This one appears to be the 351, the same engine as had been swapped into the pizza-delivery Mercury I drove in the middle 1980s. New cars sold in California around this time had these giant emissions-numbers stickers on the side glass. Later, they went on the underside of the hood.

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: 1991 Mercury Capri

Ford has gotten a lot of use out of the Capri name in the United States. First, there was the Lincoln Capri in the 1950s, followed by the Ford Capri Mk1 (which was sold by Mercury dealers in the USA but never actually badged as a Mercury). Then came the 1979-1986 Mercury Capri, built on the very successful Fox Platform and essentially a clone of the Mustang. Finally, in 1991, the Australian Ford Capri came to the United States. Here is an example of this rare car that I spotted in a Northern California self-service yard not long ago. Mechanically speaking, the 1991-1994 Capri was a Mazda 323 under the skin, complete with a member of the same B-series engine family that went into such cars as the Miata and Ford Escort. So, for a few years in the early 1990s, car shoppers who wanted a sporty Mazda convertible could choose between a Miata and a Capri. The Capri had front-wheel-drive, but could be had with factory turbocharging. These cars were reliable and fun, but had a tough time competing with the Miata in the showroom battles. You'll see the occasional example now and then, but most of the 1991-1994 Capris have met the same fate that awaits this one. Related Video:
