Junkyard Gem: 1981 Mercury Cougar XR-7

The story of the Mercury Cougar involves more plot twists and unexpected digressions than that of just about any other Detroit car, with successive Cougar generations based on the Ford Mustang (1967-1973), the Ford Torino and/or Thunderbird (1974-1979), various Fox Fords including the Thunderbird (1980-1988), the MN12 Thunderbird/Lincoln Mark VIII (1989-1997), and the Ford Mondeo (1999-2002). There were wagon and sedan Cougars for brief periods, just to confuse everybody, and the rakish XR-7 Cougars sometimes lived on different platforms from their ordinary non-XR-7 counterparts. I think the Late Malaise Era Fox XR-7s are among the most interesting of the bunch, so I was quite excited to spot this tan-over-gold '81 in a Denver yard. I tried to count the number of screaming-cat badges on and in this car and gave up once I hit a dozen. The steering wheel, door panels, C pillars, center console, and — of course — the hood ornament all boast snarling felines. Earlier Cougars had emblems showing full side views of stalking catamounts, but the Cougar logo for the 1980s showed just the head. This car got the optional center console, which I hear is quite a rarity. You had to pay $174 extra (that's around $513 in 2020 dollars) for an AM/FM/cassette audio system in the '81 Cougar, but at least the air conditioning was standard equipment. Believe it or not, thieves used to steal these radios. Kumpf Lincoln-Mercury still exists in Englewood (as Landmark Lincoln), and the yard that now houses this car can be found just 15 miles up Broadway on the north side of Denver.  The padded landau roof hasn't fared so well beneath the fierce Colorado sun, but overall this car seems very solid. Sadly, only the Mustangs and (once in a long while) Fairmonts get much love from the Fox Ford crowd these days. Three Mercury "wire wheel" hubcaps and one from a Lincoln. The base engine in the 1981 XR-7 was the "Thriftmaster" 200-cubic-inch (3.3-liter) straight-six, but very few XR-7 buyers would have refrained from checking the box for one of the two optional Windsor V8s. I can't tell if we're looking at the 255-cubic-inch (4.2-liter) version or the 302-cubic-inch (5.0-liter) one here, but real-world drivers might not have noticed the difference between the 120-horse 255 and the 130-horse 302, anyway. The non-XR-7 Fox Cougars had five-speed manual transmissions as base equipment (which nobody wanted), but all 1981 XR-7s had automatics.

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.

NHTSA investigating Ford's solution to May 2014 power steering recall

The National Highway Traffic Safety Administration is investigating a complaint that Ford's response to a May 2014 recall of the 2008 to 2011 Ford Escape and Mercury Mariner doesn't quite go far enough to solve a troubling power-steering problem. Roughly a year ago, Ford recalled nearly a million vehicles after it was found that a problem with the torque sensor's communication with the power steering control module could cut steering assistance for drivers. While manual steering would still be available, the problem was enough to ask drivers to report in to have the PSCM inspected, and if necessary, replaced (along with the torque sensor, or in dramatic cases, the entire steering column). That would only happen, though, if trouble codes were being thrown. If there weren't any problems, dealers were told to simply update the PSCM's software so that any issues between it and the torque sensor would simply throw a visual and audio warning – power steering would still be maintained. The petitioner claimed that following the recall work, he still experienced a problem with the torque sensor. According to NHTSA, a claim was made that Ford didn't go far enough in its solution to the problem, and that "the software update itself may in fact cause further issues with the affected vehicle's power steering, causing it to fail, and ultimately requiring replacement of the torque sensor or entire steering column." The petition was filed in early February and is now officially being looked into by NHTSA.
