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.

Ken Block is at it again in Gymkhana 6

If there's one thing we'll say about Ken Block and his latest installment in the Gymkhana family, it's that it's far more structured than previous videos, but that doesn't mean it skimps on the entertainment. Block is on a purpose-built course which was touted as "The... Ultimate... Gymkhana... Grid... Course" in last week's preview. Unlike Gymkhana 5, which took placed on closed streets in San Francisco, this course seems much more compact.
Block has an entire array of challenges to tackle in his 650-horsepower Ford Fiesta ST, and none of them look particularly easy. In fact, we'd argue that Gymkhana 6's grid course requires much more precise driving that previous titles. There are Segways, Lamborghinis and massive pieces of construction equipment that all must be dealt with.
We've got the entire 6:28 of Gymkhana madness for you down below. Scroll down for the video and then hit Comments and let us know how this installment compares to previous Block works.

2015 Ford Mustang invades SEMA, led by King Cobra

Ford showcased more than a dozen customized 2015 Mustangs at its sprawling 20,000-square foot display this week at the Las Vegas Convention Center as the iconic pony car's 50th anniversary celebration continued at the SEMA Show.
While Mustangs are always a hot commodity at SEMA, the new generation brought increased attention from the aftermarket, as builders like Galpin Auto Sports, Richard Petty's Garage and Vaughn Gittin Jr. offered their takes on the new 'Stang.
The extensive display included a range of Mustangs from mild to wild, with everything from a 600-plus horsepower King Cobra pictured at the top, to paint-and-wheel packages. The new regal Cobra, which we spied early in our SEMA adventure this year, may not be the replacement for the Cobra Jet as we speculated, but it does seem to point the way forward for the next iteration of a supreme Ford dragster. Fat drag slicks out back make it's reason for being abundantly clear, and for tells us that modded car is good for a 10.97-second quarter-mile run.
