Ford adding stop-start to all major model lines

Ford has gone all-in on its efforts to offer most of its new vehicles with a fuel-efficient EcoBoost engine, but the automaker is reportedly preparing to take another big step toward improving vehicle efficiency. Automotive News is reporting that Ford will soon expand the availability of start-stop technology, which was first offered - presumably the first non-hybrid vehicle, that is - on the 2013 Fusion (equipped with the 1.6-liter EcoBoost engine) as a $295 option.
The benefit of start-stop is reduced fuel consumption as it shuts the engine off at long stops, and AN quotes Ford as saying that drivers can save more than $1,000 on fuel costs over five years. Despite this, the option hasn't been popular on the Fusion thus far, but it could be more beneficial on bigger vehicles like the F-150. Ford also said that the next-gen Edge, which was previewed in concept form at the LA Auto Show, will be equipped with auto start-stop to help make the EcoBoost engines even more efficient.

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.
