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 F-150, Toyota Tacoma top ASG list of most eco-friendly trucks

No one's going to confuse the massively popular Ford F-150 pickup truck with a green vehicle, but at least it performs well in an environmental sense when compared to its brethren. The Automotive Science Group (ASG) took on the odd (to us, at least) task of measuring which pickup trucks are friendliest to the environment and found that the big seller in the Blue Oval's flagship F-series came up big, while the Toyota Tacoma came up, well, slightly smaller. That's a good thing. Among the 245 light-duty trucks that ASG studied, the 3.7-liter V6-powered F-150 won ASG's award for full-size trucks for both regular and crew cabs. Meanwhile, the 2.7-liter Toyota Tacoma, with its fuel-economy rating of 23 miles per gallon combined, had smallest overall life-cycle carbon footprint and won ASG's two mid-sized categories. Finally, the Chevrolet Silverado won best all-around performance in the full-size extended-cab category. The ASG factored in eco-friendliness, price and social performance (which is measured by, "considering the rights of those charged with vehicle manufacture and assembly") to come up with its findings. Sales of Ford's F-Series trucks rose 8.4 percent last year to 74,592 units and accounted for more than a third of the total 2013 sales of Ford and its Lincoln unit. Check out the ASG's press release below. Truck Buyers Faced With "Eco" Options Galore Which 2014 full-size trucks warrant eco claims? 25 March 2014 [Santa Rosa, CA] – With a myriad of eco-branded trucks hitting the North American marketplace in 2014 – from Ford's EcoBoost and GM's EcoTec3 to Ram's latest addition, the EcoDiesel – the Automotive Science Group (ASG) was prompted to offer an objective, scientifically-based assessment to determine exactly which 2014 trucks actually earn their "eco" badge. According to ASG and the principles of ecological economics, a vehicle's eco-rating must be multi-faceted to include both environmental and economic considerations, and so the Group's proprietary rating platform – the Automotive Performance Index – does just that. Using a unique combination of vehicle data inputs that include conventional specifications as well as social, environmental and economic performance indicators, ASG's vehicle assessments empower consumers to make choices based on one's personal principles and financial requisites.
