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.

This Mercury Cougar Eliminator is a lovely '69 survivor

If you have an overachieving brother/sister/cousin/friend (or whoever), you might know this feeling well; it can be tough to live up to those standards. In many ways, that notion can also describe the Mercury Cougar and its pioneering Ford Mustang sibling. Quite the act to follow, no? Happily though, the Cougar proved to be different enough from its Mustang relative to make a big splash, and perhaps no more so than in its racy "Eliminator" trim, new for 1969. This is one such heady Mercury, dressed in sporty Competition Orange paint, and claimed to be an unrestored "survivor." Need it in your life? The '69 Mercury Cougar Eliminator recently popped up on eBay in Chepachet, Rhode Island . The genesis of the Mercury Cougar began in 1967, really with one singular purpose—to bridge the gap between the Ford Mustang and the Ford Thunderbird with a more upscale, stylish, and chiefly more "European" feeling pony car. It's safe to say the Cougar fit the bill. Using the Mustang chassis as a base, the early Cougars were about three inches longer than their 'Stang cousins and offered better legroom, sleek front and rear fascias, and a more luxe interior. Don't mistake "upscale" for "soft" however; come 1969 the Eliminator package gave the Cougar a seriously mean attitude. Spec-up the interior package and you received high-back bucket seats, a Rallye clock, wood-rimmed steering wheel, and padded interior moldings among other custom trims. Outside is where the Eliminator really struts its stuff, though. Eliminators came equipped with a blacked-out grille, special steel wheels, an aggressive front splitter and rear wing, plus racy decals and side stripes. Four color choices were available — Competition Orange, Bright Blue Metallic, White, and Bright Yellow. As standard, the '69 Mercury Cougar Eliminator came equipped with a 351 cubic inch V8, boasting 290 horsepower, as seen in the case of this car. More powerful options were also available, as noted by Barnfinds, which included a big 390 cubic inch V8 (320 hp), a high-revving Boss 302 V8, and the gargantuan 428 Cobra Jet V8. Peek beneath the body of this Cougar and the 351ci V8 is hooked up to a desirable close-ratio four-speed manual transmission, showing a claimed 35,243 miles. Though the mileage isn't verified, the car's overall condition and wear would suggest the readings to be true. Befitting those low miles, this unrestored Cougar does carry quite the high price — a tall $32,000.

Mercury rises around sexy Cougar pack

With a slightly larger body and a more luxurious interior, the Mercury Cougar doesn't carry quite as much cachet among pony car enthusiasts as the venerable Ford Mustang. But don't try to make that argument around Cougar super-fan Mike Brown. Since starting his Cougar collecting in 1988, Brown has become an absolute expert on the model, and he claims to have owned 400 of the Mercury pony cars in that time. Ten of them are in his collection today, not to mention a heap of spare parts in the garage. Check out some of the rarer members of Brown's fleet and allow him to tell you about them in this interesting interview from Electric Federal.
