How Ford hid the 2015 Mustang from spy photographers

Now that we've finally seen the 2015 Ford Mustang, it's fun to go back and look at the spy shots we spent months pouring over, trying to dissect what was under all the camouflage. For the most part, Ford did a good job of concealing the car from spy photographers, and it released a video showing how much work went into doing so.
As crude as the Mustang's camo looked, all of the hard plastic, foam, vinyl and ratchet straps were actually created and put in place by a specific design team. The whole idea was to hide the car's identity, but it certainly ended up acting as a magnet for attention, too. According to Ford's press release, it took less than an hour for spy shots to appear online after the car was taken on public roads for the very first time - this is likely in reference to our first official spy shots of the Mustang from June, shown in the gallery below.
Scroll down for a press release and video, which shows footage of the 2015 Ford Mustang testing with minimal camouflage. This is probably the same track session where we got our first look at the Mustang's face back in August.

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.
