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.

Daily Driver: 2015 Ford Edge Sport

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, reviewed by the staffers that drive them every day. Today's Daily Driver features the 2015 Ford Edge Sport, reviewed by Adam Morath. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT [00:00:00] Hi. I'm Adam Morath for Autoblog and in today's Daily Driver we're with the 2015 Ford Edge. It's been completely redesigned and I really think that it needed it because this was always kind of the last car to come to mind when I was considering all of Ford's lineup. It was sort of forgotten. I don't think that will be the case anymore. It looks great. They revamped the exterior. The first thing I noticed walking up to the car when they first dropped it off was [00:00:30] the great job they've done with the taillights. They've got a very high tech look to them. You have LED accent lighting that surrounds the tail lamps and then a light bar that spans the entire deck lid. It looks pretty cool, very angular, a lot sportier than the previous models. We also have the optional HID headlights so if you combine that with what I've already told you about with the [00:01:00] tail lamps, and also the ambient lighting inside this vehicle ... It just feels like the lighting in general was very well considered on the Edge and gives it a very modern feel. The nice design continues to the interior as well. You've got leather panels with contrast stitching on the sport model. You've got a nice center console that actually has some storage underneath it, so it's sort of a floating center console. The only thing is there is still a little bit of cheap plastic [00:01:30] used on the interior. That's a common complaint of automotive journalists worldwide, but this one I can see already has a few scratches on it. You can also get this vehicle with 20-inch aluminum wheels or 21-inch matte black aluminum wheels. Here we've got them wrapped in Perelli. I haven't been on a track or anything where you could really get a sense of the performance, but again, that just adds to the sporty look of the Edge in the sport trim level. It has the new 2.7 [00:02:00] liter Eco Boost V6 and I have been really happy with this powertrain. It puts out 315 horsepower, 350 pound feet of torque, and that's that twin turbo working for you. It helps with acceleration and passing at highway speed, so it checks both boxes there.

Rolling footage of the 2015 Ford Mustang hits YouTube [w/video]

Just in time for the holidays: Ford took the 2015 Mustang to Route 66 to cook up rolling footage, and we've been given some of the leftovers ahead of the meal. There are no burnouts, no donuts, no revving, and thankfully, no music. It's just two minutes and 26 seconds of the new pony car running free in the desert.
So in case you needed more visualizing help, the video below will help you start imagining how you'll look in your 2014 Christmas present to yourself...
