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 XR2

Just a year after the Mazda MX-5 Miata first went on sale in the United States, Ford's Mercury Division began selling a similarly-priced two-seat convertible here. This was the 1991-1994 Mercury Capri, and I've found an example of the hot-rod turbocharged version in a northeastern Colorado car graveyard. The Capri name has an illustrious history within the Ford Empire. First used on a Lincoln in 1952, it went on to serve as the name for a hardtop version of the early-1960s Ford Consul in the UK, then as the designation for a low-end trim level on the 1966-1967 Mercury Comet. Starting in the 1969 model year in Europe (1970 in North America), Ford began selling the best-known Capri of all: a sporty coupe based on the Cortina, sold through Mercury dealers in the United States but never badged as a Mercury here. Sales of that Capri halted here after 1978 (they continued through 1986 in Europe), but the Mercury Division then moved the name over to its version of the 1979-1986 Ford Mustang. After that, Ford Australia took the Capri name for a new Mazda 323-based sports car beginning in 1989. Then Dearborn decided that an Americanized version of the Australian Capri would be a success on this side of the Pacific, and left-hand-drive Capris began showing up in American Mercury showrooms in late 1990. Today's Junkyard Gem is one of those first-model-year cars, and it's the very rare turbocharged XR2 version. While this car was intended to be a competitor for the Miata, it's really that car's Mazda cousin. Both cars got their power from 1.6-liter versions of Mazda's versatile B engine, though the Capri had the same front-wheel-drive setup as its 323/Protege (and Escort/Tracer) platform siblings. At the same time, Ford was selling Kia-built Mazdas with Festiva (and, a bit later, Aspire) badging, alongside Mazda MX-6s with Probe badges. Just to make things interesting, American Mazda dealers were selling Ford Explorers as Mazda Navajos, while Rangers with Mazda badges followed starting in 1994. The 1990s were Mazda-riffic times at Ford! This car wasn't the first Australian-designed, Mazda-based Ford product sold in the United States. That honor belongs to the 1988-1989 Mercury Tracer, which was based on the same Mazda 323 platform as the Capri and built in Mexico. Later on, the Tracer remained a member of the 323 chassis family but was a nearly identical twin to its Ford Escort sibling.

Junkyard Gem: 1991 Mercury Grand Marquis LS

Ford's now-defunct Mercury Division first began using the Marquis name in 1967, on a sporty full-size hardtop based on the Ford LTD, then began offering the Grand Marquis beginning in the 1979 model year. These big, boxy luxury sedans were replaced by big, curvy luxury sedans (on the same platform) starting with the 1992 model year, so today's Junkyard Gem is one of the very last squared-off Grand Marquises ever built. The 1991 Grand Marquis (or "Grandma Keith," as many refer to it today) looks nearly identical to its 1979 predecessor at a glance, just as the 2011 model doesn't differ much from the 1992 model. Ford saw no reason to follow short-lived fashion trends with its simple, sturdy rear-wheel-drive sedan. Only two Grand Marquis trim levels were available for 1991: the base GS and the (somewhat) upscale LS. The former listed at $18,741 and the latter at $19,241, which comes to about $41,494 and $42,601, respectively, in inflated 2022 dollars). This interior would have seemed comfortingly familiar to a 1968 (or even 1958) Mercury owner time-traveling to 1991.  This is the optional "full grain leather seating surface," which cost an extra $489 (about $1,083 today). Dig those opera lights! Air conditioning was standard equipment in the 1991 Grand Marquis and its wagon counterpart, the Colony Park. The engine is the good old pushrod 5.0-liter Windsor V8, which would be replaced by a far more modern 4.6-liter SOHC mill in the '92 Grand Marquis. This engine was rated at 180 horsepower. A four-speed automatic was the only transmission available. The early 1990s ended up being the last gasp for padded vinyl roofs being considered mainstream equipment on new Detroit cars; this one was called the "Formal Coach" roof and cost an additional 725 bucks ($1,605 now). Such roofs were still available on a few cars later in the decade, but their time had passed. Why would such a clean Grandma Keith end up in a place like this? That's easy: it got T-boned directly into the right front wheel, mangling the body and bending up the suspension. This damage might have been worth fixing when the car was five years old, but it's a write-off when it happens to a 31-year-old Ford Panther. 1991 Mercury Grand Marquis Commercial - Savings Ad The granddaddy of them all, and on sale in South Texas!
