2014 Ford Fiesta 1.0L EcoBoost to hit 45 mpg for $16,445*

When Ford first announced its plan to put the 1.0-liter EcoBoost three-cylinder engine under the hood of the 2014 Fiesta, it promised hybrid-like fuel economy without a hybrid-like premium. We're still waiting for official specs on this engine, but thanks to the EPA's fueleconomy.gov website and Ford's retail site, we now know what customers can expect in terms of both fuel economy and price.
All along, Ford has said that it expects the 1.0-liter EcoBoost to get more than 40 miles per gallon on the highway, and now the EPA backs this up with official ratings of 32 mpg in the city and 45 mpg on the highway. These numbers are an increase of two mpg city and four mpg hwy compared to the current fuel-sipping Fiesta (the 1.6 SFE), and it also beats other three-cylinder cars for highway mileage like the 2014 Mitsubishi Mirage (44 mpg highway) and 2014 Smart Fortwo (38 mpg highway); the Fiesta 1.0 EcoBoost is lower than both three-pot rivals, though, in city fuel economy with the Mitsubishi getting 37 mpg city and the Smart rated at 34 mpg city. This model handily beats high-volume small cars like the Honda Fit, Toyota Yaris and Chevy Spark in both city and highway numbers.
As for pricing, the 1.0-liter EcoBoost is offered on both the sedan and hatchback as a $995 option called the SE Manual EcoBoost package, which is aptly named since it's only offered on SE trim-level Fiestas equipped with a manual transmission. Along with the engine, the package also comes with 15-inch steel wheels, regenerative brakes and a decklid spoiler on the sedan. This means the four-door Fiesta 1.0 EcoBoost will start at $16,445*, or $17,045* for the hatchback (*not including $795 for destination).

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.

NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.
