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.

Car and Driver lists 10Best for 2013, same as it ever was

Forgive us for having the distinct feeling of déjà vu, but it certainly feels like we've been here before. By that we are referring Car and Driver and the announcement of its annual 10Best vehicles for 2013. To be sure, it's an impressive selection of cars that combine heart-pounding performance and frugal sensibilities, but it also represents something of a broken record on the part of C/D. We're not so sure that's a flaw, though, as the resulting list is tough to argue with.
Vehicles like the Ford Mustang, Porsche Boxster, and BMW 3 Series have maintained their high-horsepower spots on this list for several years now. Even on the more practical and nimble end, the Honda Accord, Honda Fit and Mazda Miata have not budged. These continued spots are even in light of redesigns for some vehicles such as the Accord, Boxster and 3 Series.
In fact, the only newcomer to the 10Best list this year are the Scion FR-S/Subaru BRZ twins, which knocked out the Cadillac CTS-V. We think it would have been a huge misstep to have excluded the FR-S/BRZ, even in light of the supercharged Caddy's lamentable departure from 10Best.

Ford 1.0L EcoBoost 3-Cylinder: Autoblog Technology of the Year award finalist

As the old saying goes, "There's no replacement for displacement." But these days, many automakers are launching powerful, downsized engines that offer similar or better power output than their predecessors, all while offering improvements in fuel economy and emissions. These days, we're seeing automakers replacing eight-cylinder engines with turbocharged sixes, and the naturally aspirated six-cylinder motors are being phased out in favor of potent turbo fours. But Ford has gone even smaller, offering a three-cylinder, turbocharged engine with one single liter of displacement.
Sure, three-cylinder engines aren't anything new - they've been offered around the globe for ages. But Ford's EcoBoost 1.0L powerplant is perhaps the best application the Autoblog team has tested. Gone are the triple-cylinder complaints of yore - this engine doesn't sound anemic or buzzy, and there's healthy power output on tap. In fact, compared to the 1.6-liter inline-four that Ford also offers in the Fiesta, the 1.0-liter is more powerful, while boasting an impressive 45 miles per gallon on the highway.
This engine has already received numerous accolades, including winning the International Engine of the Year award in 2012, 2013 and 2014. The 1.0L EcoBoost will be available in the refreshed 2015 Ford Focus here in the US.
