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.

Wards names its 2015 10 Best Interiors list

Wards Automotive has named the winners of its 10 Best Interior awards, covering a wide but affordable array of vehicles. Where last year's list contained two six-figure vehicles, including the $372,800 Rolls-Royce Wraith, this year's is, well, a whole lot more reasonable. The publication lists the Mercedes-Benz C400 at $65,000 (which seems off), making it the most expensive vehicle here. That said, we'd argue that the entire C-Class line deserves to make this year's list, owing to its varied and high-quality selection of materials. The other vehicle to break the $60,000 mark, meanwhile, is the $60,675 Ford F-150 King Ranch, which has 327,000 pounds of leather lining its interior. Only one other German car, the BMW i3, and one other pickup truck, the GMC Canyon, managed to make this year's list. Here's the full list of this year's winners: 2014 BMW i3 ($52,550) 2015 Chrysler 300C Platinum ($51,175) 2015 Ford F-150 King Ranch ($60,675) 2015 GMC Canyon SLT ($40,465) 2015 Honda Fit EX-L ($21,590) 2015 Jeep Renegade Limited ($33,205) 2015 Kia Sedona SXL ($43,295) 2016 Mazda6 Grand Touring ($33,395) 2015 Mercedes C400 ($65,000) 2015 Nissan Murano SL ($41,905) See what we mean about the mainstream vehicles? Not only is there a distinct lack of luxury brands, it's the price of some of the vehicles that surprise. The Honda Fit, Jeep Renegade and Mazda6 are very reasonably priced, especially when you compare Wards price with the starting price. The Renegade Limited starts at less than $25,000, the Mazda at less than $22K and the Fit at under $16,000. Head over to Wards for a more detailed explanation of why each vehicle won.

Ford Fiesta ST orders off to strong start

We at Autoblog love the new little Ford Fiesta ST, and apparently, folks in Europe are pretty impressed with it, as well. According to Ford, the automaker's European arm has already logged 3,000 orders for the new hot hatch since it hit dealerships this March. The US-spec car, which will only be available as a five-door, will go on sale in the United States this summer.
What's perhaps most interesting about the Fiesta ST ordering is that the majority of customers appear to be ordering high-spec cars. According to Ford data, 60 percent of customers have opted for the leather interior with Recaro buckets, and 90 percent have selected the upgraded 17-inch wheels (seen on our test car, above). Spirit Blue has been the most popular color, commanding 27 percent of all orders. As for the technology upgrades, 19 percent of customers have ponied up for the Sony stereo with navigation.
To recap, the Fiesta ST is offered with Ford's 1.6-liter EcoBoost four-cylinder engine, putting out 179 horsepower and 177 pound-feet of torque, mated exclusively to a six-speed manual transmission. We had an absolute blast flinging the hot Fiesta through the French Alps, and we can't wait for this sharp little hatch to make its way over to the States.
