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.

An in-depth look at the Ford GT with Xcar

Ford made big waves when it unveiled the new GT at the Detroit Auto Show this past January. But as far as details go, it's been rather quiet. Though Dearborn has revealed what engine will sit between those buttresses, it hasn't told us exactly how many horses or torques it will produce, or precisely how fast we should expect it to propel the new all-American supercar. Fortunately, the automaker let the crew at Xcar into the studio to give us a quick, four-minute rundown of all the information that is out there at the moment, along with all the most intriguing angles of the vehicle's design. The historically savvy among us will already know that the new 2016 Ford GT traces its roots back to the GT40 that conquered Le Mans half a century ago, and through the previous Ford GT that debuted a decade ago. Both of those featured V8 engines (supercharged in the latter case) while their modern successor goes with a twin-turbo V6. But as Xcar points out, six cylinders aren't without their precedence in the history of the GT-series Ford supercar: the GT70 rally car of 1970 originally packed a 2.6-liter V6. That engine was later replaced by a 1.6-liter inline-four, which puts another crack in the theory of the eight's hegemony over the history of the series – as does, we'll point out, the Bugatti-like quad-turbo V12 that featured in the GT90 concept of 1995 that sadly never made production. The point is that divergence from V8 tradition shouldn't dissuade anyone from getting excited over the arrival of the new GT, and we're looking forward to seeing what she can do – on and off the track.

Ford gets dirty testing the 2017 Raptor

Want to hear the sweet sound of turbochargers spinning merrily away underhood of a 2017 Ford Raptor pickup truck test mule? Of course you do. And we're happy to oblige. Fortunately for you, those aren't the only sounds you'll hear when you watch the video above. We noted plenty of birds and insects, too, which means Ford has finally seen fit to share some good old fashioned muddy off-road footage of its upcoming off-road superstar as it is subjected to rigorous testing ahead of its on-sale date in the fall of 2016. It's no secret that we're big fans of the first generation of the Ford Raptor. If there was one complaint we've voiced about the truck, it's that the off-road-specific pickup could use a touch more power. Fortunately, more power is coming for 2017 as Ford replaces the outgoing 6.2-liter V8 with a new version of its 3.5-liter twin-turbo EcoBoost V6. We don't know exactly how many horses the new truck will corral, but we know it will be more than the 411 horsepower and 434 pound-feet of torque offered by the previous truck. This is the second time Ford has let out some interesting information about its tests of the next Raptor, the first focusing specifically on grueling desert trials. Considering the promises Ford is making about the 2017 Raptor's various off-road capabilities, we're keen to put the pickup through its paces ourselves. For now, though, join us in watching the video above. Related Gallery 2017 Ford SVT Raptor Desert Testing News Source: Ford Ford Truck Off-Road Vehicles Videos ford f-150 svt raptor ford raptor
