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.

2015 Ford Mustang Convertible shown on Twitter [UPDATE w/video]

It hasn't yet been 12 hours since the hotly anticipated 2015 Ford Mustang has been let out into public view. After a series of evocative leaks over the course of the last days, we brought you a full deep dive of the sixth-generation pony car at the dawning of today. And yet, here we are rushing to bring you news of a new Mustang variant, already.
Be it part of a plan to keep the Mustang fervor at full boil, or a misunderstood email somewhere in the chain of command, Ford UK has unceremoniously tweeted a picture of the 2015 Ford Mustang Convertible. For a newly global Mustang, getting our first look at the droptop from the convertible-crazy British does make some amount of sense.
As for details, well, you're looking at them. Brandon Turkus reported yesterday that the Mustang 'vert would make use of a fully electric convertible mechanism, and that it would be of fabric construction rather than some kind of retractable hardtop. We see here that the fabric part is clearly true, and it does look as though Ford may still be employing the same kind of manually attached tonneau cover that exists right now. Of course, our view from this angle isn't great, and the particulars are still up in the air.

Europe's most-wanted classic car is... the Ford Mustang?

Over the span of its 49 years and five generations, the Ford Mustang has held a special place in the hearts of automotive enthusiasts in the US, but, as it turns out, this car is also very popular amongst European car lovers. Earlier this summer, AutoScout24 - a new and used car shopping site in Europe - polled around 75,000 European "car lovers" (not sure how they vetted the respondents) to see which cars were the most popular, and the Mustang came out on top over iconic European classics like the BMW M1 and Volkswagen Beetle.
In the whole of Europe, 37 percent of those polled dream of owning a Mustang, but that number jumps in individual countries like Austria (42 percent) and Spain (41 percent). Rounding out the top five popular classics in Europe are the Mini and Citroën 2CV. Find out which cars made up the rest of the top 10 in the press release posted below.
