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.

Tanner Foust tackles 'Ring in SVT Raptor

Here's a math problem: if Tanner Foust has a 24 hours to kill in Germany and one blue Ford Raptor, how long will it take him to decide he wants to lap The Nürburgring? Extra credit if you can get your answer precise to the millisecond.
A very truck-like and slidey lap of the 'Ring is exactly what happened when the Ford-sponsored rallycross driver took time off from set-up duties for his 'day job.' Thankfully no one even thought to worry about posting a time, but you can watch some Raptor skid marks getting laid down between the kerbs in the video below.

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.
