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.

Report: Lincoln getting all of Mercury's ad dollars

Now that the curtain has closed on Mercury, Ford Motor Company will redirect all of its marketing dollars for the oft-overlooked brand to the Blue Oval's luxury outpost, Lincoln. In speaking to Automotive News, the chairman of the Lincoln National Dealer Council, Bob Tasca, Jr., said, "You'll see a lot stronger presence in the advertising of Lincoln in 2011."
Lincoln spokesperson Christian Bokich reminded AN that the automaker is "preparing the way for seven new or significantly refreshed vehicles" that will be launched over the next four years, and the largest ad blitz in 2011 will focus on the refreshed MKX crossover, as well as the MKZ sedan and its hybrid counterpart. Following that, Lincoln has plans to launch a completely overhauled version of its Navigator SUV, an all-new C-segment vehicle and the overhauled 2013 MKZ, which Tasca says will be "strikingly different from its Ford Fusion sibling."

eBay Find of the Day: Mercury Marauder two-door convertible

Never underestimate what you'll see on eBay Motors. Take this unique creation, for example. Near as we can tell, it's the same 2002 Mercury Marauder that was modified into a two-door convertible by Ford for the 2002 Chicago Auto Show. According to the seller, this car still boasts its Eaton supercharger bolted to a 4.6-liter V8 engine, and at the time of its debut, the engine was rated at a lofty 335 horsepower. We have a hard time believing that the extra ponies would do much to offset the weight of the additional frame stiffeners and top mechanism on the car, however.
The vehicle is currently offered for sale by a dealer in Lansdale, Pennsylvania, though the listing is mum on how the convertible managed to make its way from Ford's Windy City show stand into the seller's inventory. If you like what you see, the machine can be yours for the princely sum of $75,000 or best offer. Head over to eBay Motors to take a gander at the listing.
