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.

Bill Ford says carsharing helps Ford, EVs need to be clean

To most people, Bill Ford is most famous for being the great-grandson of Henry Ford. But, as the executive chairman of Ford Motor Company, Ford has also been leading the company into greener and greener territory. At the morning plenary session for the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit today, Ford discussed a wide variety of topics, including connected cars (of course), plug-in vehicle and how Ford's collaboration with Zipcar came about because of he liked what the Zipcar CEO was excited about getting cars off the road. Given that the conference has a big focus on communication between cars this year, it's no surprise that Ford talked about his company's work on that front. He's looking at the long term, though, and says that despite announcements like the one General Motors made yesterday about Super Cruise, when fully autonomous vehicles get here, it won't be headline news since the ground work is being laid by technologies coming to cars in bits and pieces now. In other words, your adaptive cruise control is getting ready for bigger and better things. "My fear is that we electrify the fleet and our impact is not what it could be." – Bill Ford On the zero-emission vehicle front, Ford said that while he's in favor of electric vehicles, "My fear is that we electrify the fleet and our impact is not what it could be." He was discussing the emissions reality of coal-powered electricity, and said that, "We've got to have a national discussion about what we want our grid to look like." As for the work that Ford is doing with Zipcar (which is just one of the many automaker carsharing operations out there today), Ford said that he first approached Zipcar CEO Scott Griffith after hearing Griffith talk at a green conference four or five years ago. Griffith was surprised, Ford said, because he had just given a talk about ways to reduce car ownership. "Did you hear my speech? I talked about taking cars off the road," Ford remembers Griffith saying. "Yeah, and what's going to happen without us," Ford responded. Today, the partnership allows Ford to get cars to people that have traditionally been "hard to reach," like college students on campuses. Ford's vehicles are currently available on 250 colleges campuses. Ford then spoke favorably about other challenges to the traditional car ownership model, like Lyft and Relay Rides. "Rather than being frightened by that, we need embrace it and help makes their companies better," he said.

These horribly misguided front-drive design studies nearly became the Mustang

As we eagerly await the unveiling of the all-new sixth-generation Mustang, Ford has been giving us some great information over the past few months showing what has gone into shaping its venerable pony car. As many changes as the Mustang has gone through in its 50 years, though, it appears the fourth-gen model played a decisive and pivotal role in the car's future.
As is part of Mustang lore, the front-wheel drive Ford Probe was originally developed as a next-generation Mustang in the Eighties before cooler heads prevailed. The Blue Oval has just released a handful of images showing how bad things could have been - including a full-scale clay model of a front-wheel-drive Mustang (shown above). Fortunately, the FWD Mustang plan was scrapped and Ford went to work designing a rear-wheel-drive replacement for the Fox Body Mustang, with three design studies making it far enough to become full-scale models. These include the soft "Bruce Jenner" Mustang, the over-the-top "Rambo" Mustang and the middle-ground "Arnold Schwarzenegger" Mustang, which finally became the basis for the 1994 'Stang.
By early 1991, the design language of the fourth-generation Mustang had been worked out, and the rest, they say, is history. Scroll down for the fascinating press release telling the story of the fourth-gen Mustang, and be sure to check out the gallery of horribly misguided sketches and various design studies that were all on the table in the late 1980s.
