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.

Is this '47 Chevrolet a rat rod or a sports car?

These days there are plenty of vehicles that blur the conventional automotive class structures. For instance, was the Honda Crosstour a wagon or an SUV? And what exactly was the Nissan Murano CrossCabriolet? Regardless, those line-blurring cars (or trucks) are out there, and though this one didn't roll off a production line, it's still quite the automotive head-scratcher. Hailing from Missouri, this epic creation is one part mad science experiment, one part 1947 Chevrolet pickup, and one part '95 Mercury Cougar. Add it all up and you get an awesome truck-sports-car hybrid, complete with an outrageous wing and a V8 to boot. And interestingly enough, it's up for sale . RELATED: Check out this Wild-Styled Lamborghini Rat Rod So how does it all come together? According to the listing, the Chevrolet truck cab (which had previously been chopped) was sanded down to bare metal and given a thorough shellacking of clear coat. It was then melded together with the front end of a 1995 Chevrolet S10 pickup truck, and set low to the ground on Bilstein suspension drop spindles. Stance achieved. But instead of fielding an engine from either of those pickups, it pulls its heart from a 2005 Chevrolet Tahoe SUV—a big 5.3-liter V8 heart, that is. It comes backed-up to a GM Turbo 400 automatic transmission. Towards the rear however is where things get really interesting. A Copper Pearl coated tube frame chassis both attaches the rear independent suspension (a la Mercury Cougar) to the racy spoiler, as well as secures the rat rod's rear-mounted radiator, fan, and fuel tank. I'm not quite sure why, but it just looks glorious. RELATED: Reports Say Mid-Engine Corvette Will Arrive in 2018 Inside the vintage cab, the Chevrolet furthers its racing proclivities (it's said to have won burnout and auto-cross events) with a pair of harnessed racing seats, a drift brake, a detachable steering wheel, and a tachometer with oil and temperature gauges, but oddly no speedometer. The shifter is a crescent wrench. And its shift boot? That's a Crown Royal Purple bag. All in all, this grin-worthy Frankenstein creation tallies up bits and pieces from four different vehicles (five if you include the Camaro wheels), which make it truly a mash-up of epic proportions. Internet, what do you think? Related Video: This article by Zach Doell originally appeared on Boldride.

Junkyard Gem: 1973 Mercury Marquis Brougham 4-Door Pillared Hardtop

Ford's Mercury Division debuted the Marquis in the 1967 model year, as a sporty coupe based on a stretched Ford LTD chassis. When the LTD got an update for 1969, so did the Marquis, and production of that generation of the top-of-the-line Mercury continued through 1978 (the Grand Marquis hit streets the following year). The 1969-1978 Marquis was a big, imposing land yacht, and the Brougham version came absolutely loaded with affordable luxury. Today's Junkyard Gem is a Marquis Brougham from the first year of the Malaise Era, found in a Phoenix self-service car graveyard recently. This car appears to have spent decades sitting outdoors in one of the harshest climates in the country, and so it's in rough shape. The vinyl top received the full thermonuclear treatment and is mostly obliterated by now. The interior got thoroughly cooked as well. Still, its original opulence shines through if you use some imagination. What hurts is that this car was packed with most of the good options, including the mighty 460-cubic-inch (7.5-liter) V8 engine with four-barrel carburetor. The price for the 460 was just $76 in this car, or around $548 in today's money. The base engine was a 429 (7.0-liter). Power numbers were way down for 1973 when compared to a couple of years earlier, partly as the result of tightening emissions standards but mostly due to the switch from gross to net power ratings that began midway during 1971 and was completed by the end of 1972. This engine was rated at 202 horsepower and 330 pound-feet. The only transmission available was a three-speed automatic. We can assume that the original buyer of this car and its single-digit fuel economy had a rough time when the OPEC oil embargo hit in the fall of 1973. Believe it or not, air conditioning was not standard equipment on the '73 Marquis Brougham (you had to move up to a Lincoln for that). This one even has the automatic temperature control feature, adding a total of $508 to the cost of this car (about $3,661 in 2023 dollars). That AM/FM/8-track radio—or, in fact, any radio—was an extra-cost option as well, with a price tag of $363 ($2,616 after inflation). The MSRP for the 1973 Marquis Brougham sedan (known as a "pillared hardtop" thanks to the frameless window glass) was $5,072, which comes to $36,555 in today's dollars. Obviously, its out-the-door cost would have been much higher with all the options.
