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.

Mysterious small Ford spied in Germany

Our spy photographers have just popped off a few shots of something curious. This little runabout was spotted in Germany out testing with a current-generation Ford Fiesta. We're fairly confident the machine is a Ford, but exactly which Ford model is up for debate. The hatchback could be the next-generation Ka, but we've also heard that the Blue Oval supermini might not get a replacement. Our shooter says the five-door is a bit smaller than the current Fiesta, though there is a chance that this rig is just an engineering mule for drivetrain development. Then again, it could be a model built specifically for the South African market or China, or not a Ford at all.
Whatever it is and wherever it's headed, you can check out in the gallery for a closer look before heading into Comments to weigh in with your best guess.

Ford F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.
