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.

2015 Ford F-150 named Truck of Texas, Lincoln and Jeep also awarded at Truck Rodeo

The Ford Motor Company has a lot of reasons to celebrate after winning eight categories in this year's Texas Auto Writers Association's annual Truck Rodeo. Most important among them, the Blue Oval's latest 2015 Ford F-150 earned the prestigious Truck of Texas award, ending the Ram 1500's two-year winning streak. The 2015 Lincoln MKC also grabbed the honor as the CUV of Texas, and Ford was named Truck Line of Texas.
FoMoCo even took trophies for best technology with its extensive use of aluminum on its latest F-Series and best commercial vehicle for the new Transit 250. It wasn't a total sweep, though, because the Jeep Grand Cherokee grabbed the title of the SUV of Texas for the fifth straight time.
This year's event put 60 auto writers in 75 pickups, SUVs and crossovers and challenged them to find the best in a plethora of categories. All of the winners are listed below, and scroll down to read the full announcements from the Texas Auto Writers Association and Ford.

Daily Driver: 2015 Ford Flex

The Ford Flex has been around. It's not T-Rex or even Model T old, but still; it's been hauling people and stuff since 2008 without a major redesign. That's quite a long time in the car world. Sales have been sliding the last couple of years, and the Flex is now considered a niche player in the crossover-centric US auto market. But that doesn't mean it's still not a pretty good vehicle for its purpose: If you need to haul people and stuff, there are few better choices. Some even think it's a guilty pleasure. I spent a winter afternoon tooling around suburban Detroit in a handsomely equipped Flex Limited. We're talking the 3.5-liter EcoBoosted V6 with 365 horsepower and all-wheel drive. Inside, there were big comfy seats, lots of leather, acres of storage space and even a built-in refrigerator. The drive ended up being surprisingly fun. If there's such a thing as a hot-rod minivan, this is it. I also got noticed. The Flex's boxy design has aged well. It's still polarizing, but there aren't many contemporary vehicles that look like a Flex. So if you've ever seen a Flex on the road, and thought: "Man, that thing is big. I wonder what it's like to drive that?" Now's your chance to find out.
