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.

Autoblog's June 2019 Editors' Picks

Each year we review, test and rate hundreds of brand-new cars, trucks and SUVs. We rate these vehicles using the Autoblog score, giving a select few our Editors’ Pick. Here are the best cars we drove in June 2019. 2019 BMW 8 Series Everyone on the Autoblog staff loves a good grand tourer, so we were excited to get behind the wheel of the revived BMW 8 Series, specifically an M850i Coupe. A good GT needs to be as fast as it is stylish and comfortable, and the new 8 Series delivers. We particularly like the 523-horsepower twin-turbo 4.4-liter V8Â’s copious power and smooth ride quality, even on MichiganÂ’s pockmarked post-winter roads. We dig the interior design, too, though not everyone was in love with the exterior. ItÂ’s not the best-handling car in its class, and doesnÂ’t hide its sizable proportions very well, but itÂ’s still worth a look if youÂ’re looking for a big, fast cruiser.  2019 Ford Expedition Crossovers may be the hottest vehicles on the market, but thereÂ’s still a sizable demand for traditional body-on-frame SUVs like the Ford Expedition. These behemoths offer plenty of space in addition to truck-like capability. We like the Expedition's smooth ride, powerful twin-turbo V6 and sharp exterior design, though the interior can feel a bit cheap, especially on some of the more expensive trims. Adding options quickly puts it into Lincoln Navigator territory, and itÂ’s hard to recommend the Ford over the Lincoln when the latter packs the same capability into a far nicer package. Still, the Expedition is as good or better than the competition in most respects, and thatÂ’s why itÂ’s one of our picks. 2019 Toyota 86 Few cars at any price point are as much fun as the Toyota 86 (and its twin, the Subaru BRZ). We like the 86Â’s balanced chassis and sharp steering, and while itÂ’s not as nimble as its close rival the Mazda MX-5 Miata, the ToyotaÂ’s back seat and trunk make it a more usable vehicle. But while we like the 86Â’s driving position, the rest of the interior feels cheap and dated, especially the infotainment system. We complained about the anemic powertrain back in 2012, and itÂ’s only gotten worse as the years have gone by.

Barrett-Jackson 2014: First production 2015 Ford Mustang earns $300k for JDRF [w/video]

We've almost become immune to the huge dollar amounts that collectible cars earn for charity at Barrett-Jackson. To wit, $300,000 for the first production 2015 Ford Mustang initially didn't seem like very much money. In reality, though, it's probably about 10 times the actual asking price for the car, and we're pleased to report that 100 percent of the proceeds will go to the Juvenile Diabetes Research Foundation.
According to Ford, the car's winning bidder will get to "choose a fastback with manual or automatic transmission, and any interior, exterior and stripe color combination offered by Ford on the all-new Mustang." Power will come from a slightly revised version of the well-known 5.0-liter V8 engine that will produce "more than 420hp and 396 pound-feet of torque."
We snapped live images of the 2015 Mustang prototype that Ford had on display here at Barrett-Jackson, and you can check them out above. The official auction description, along with a video of the auction as it happened live, is below.
