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.

Ford gets its Movement on, releases 'Sounds of Focus' tracks

Ford has, for at least the second year in a row, teamed up with techno promoter Paxahau and a couple of artists to make music in recognition of the Detroit Movement music festival. This time, Movement performers Ataxia and Secrets were selected by Ford, and were invited to spend some time at the automaker's Michigan Assembly Plant, which gives birth to the Ford Focus and Focus Electric models.
Now that we know the what, how about the why? According to Ford, "Detroit is uniquely tied to the origins of the electronic music scene. In the 1980's variations of electronic music stemmed from inspirations of industry, including the automotive sector." So, there you go. If you're interest is piqued, feel free to read the press release, watch the video and listen to the tracks below.

XCAR stages epic drag race between Ford GT40, GT70 and GT

XCAR has put together what it believes is a first - a drag race between Ford's legendary, Le Mans-winning GT40, the more recent GT supercar it inspired and the little-known GT70 rally car. The three mid-engined monsters were all built for very different purposes, and not surprisingly, they come to battle with very different powertrains.
The GT40 is powered by a thumping, naturally aspirated V8. This example, which looks like a Mark IV model, is likely powered by a 7.0-liter engine, although it's not entirely clear how much power it's putting down. The GT70, meanwhile, was Ford's response to the Lancia Stratos. Considering that the Lancia is one of the greatest rally cars in history and many of you are probably just hearing of the GT70 for the first time, you can imagine how much success Ford had with it. Only six were produced before a change in regulations doomed this mid-engined rally car.
The Ford GT, meanwhile, doesn't really need an introduction. 550 horsepower is on offer from a 5.4-liter, supercharged V8, which keeps the GT competitive even against more modern supercars. 60 miles per hour arrives in well under four seconds while the top speed sits at 212 mph. Not bad for a car that went out of production in 2006.
