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.

Ford forced to recall Escape over fire risk yet again

Recalls happen. Automakers hope they won't, but they do. And that's alright, for the most part, because cars are designed (and to a large degree still made) by humans, and humans make mistakes. So we forgive them, as long as the problem is resolved. Only in the case of the Ford Escape, the problem seems to keep coming back.
That's why Ford is calling in the Escape yet again due to fire concerns. The issue revolves around problematic fuel lines in 9,469 units manufactured between October 5, 2011, and July 11, 2012, all of which use the 1.6-liter EcoBoost inline four-cylinder engine.
As you yourself may recall, the Escape was subject to a string of recalls last year that resulted in a $17 million fine. One of them was over this very same issue, which Ford apparently didn't rectify the first time around. Let's hope this time is the last time.

2015 Ford Mustang stars in bizarrely awesome '80s aerobics video

For reasons we can't comprehend, here's a music video starring the all-new, 2015 Ford Mustang and a number of dancers dressed and styled in the most stereotypically 1980s way possible. The dancers then take part in a male-versus-female dance off. Again, we've no idea why it exists.
It's weird, and for the second time in two weeks, we're sat at our computer wondering, "What are we watching?" That said, it does show the new Mustang from a number of angles, and it's one of the first car-related YouTube videos we've seen that's available in a 4K, ultra-high-def stream.
