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.

Our interview with Jeremy Clarkson and James May, plus SEMA! | Autoblog Podcast #491

This week, David Gluckman and Mike Austin talk SEMA madness, mis-aligned steering wheels, wireless charging, McLarens (they're sports cars!), and decals. We also have an excerpt from a recent interview with James May and Jeremy Clarkson of The Grand Tour and Top Gear fame. As always, we talk about a variety of cars we've been driving and then respond to some questions from listeners. And as a bonus, there's a trivia question mixed in. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want questionable buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. Oh, and please send trivia questions! You'll get the honor of stumping your fellow listeners, and we'll thank you too.

2014 Ford Fiesta Titanium

You might not be interested in owning a subcompact (B-segment) hatchback for $20,000. Let's be clear from the get go here: there are any number of reasonable arguments for staying away from the highest-content versions of these small cars. Ford's player in the B-segment arena is the newly updated 2014 Fiesta, and the Titanium trim represents the most luxurious instantiation of the model. We recently were loaned a Fiesta Titanium for a week, whose final sticker price hit $20,390, with navigation being the only standalone option added to the bottom line. By way of comparison, the most basic version of the all new, one-segment-up Mazda3 hatchback costs $19,740 with delivery and destination accounted for, and no options added on.
Hold on to that thought for a moment, we'll get back to it.
