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.

Ford Escort Concept goes back to basics

Here's the thing about China: The folks buying cars there have a very different set of standards than shoppers in many other markets around the globe. While we all drool over hot metal with bold designs, and while we appreciate automakers going an extra step to inject even their cheapest offerings with aggressive and interesting cues, that sort of sheetmetal sex appeal doesn't always sell in the People's Republic. Case in point is Jaguar, which may be designing a more traditional-looking version of its XJ for the Chinese market, or more to the point of this story, Ford currently sells the less-exciting, last-generation Focus compact in China right alongside the new one.
So consider this new Shanghai-bound C-segment concept a preview of what's to come for that more traditional, budget-minded, less-sexy market. More proof of this pudding: Ford's even calling this concept the Escort - a nod to the Blue Oval's compact car days of yore, and a name that stirs up thoughts of basic, affordable transportation rather than great driving dynamics or bold design. "Customers in China described seeking a vehicle that is stylish - but not one that is arrogant or pretentious," Ford states. And this new Escort concept previews a possibility of providing exactly that for this rapidly expanding automotive market.
What you're looking at, then, is one of the most simple Ford designs we've seen of late, though it still incorporates all of the automaker's latest DNA. The signature hexagonal grille is front and center, flanked by attractive LED headlamps and chrome-rimmed foglamp housings. The entire car's design focuses on clean, smooth surfaces, with one strong character line flowing from front to back just below the beltline. We will say that the car looks decidedly more premium from the rear view, where narrow, horizontal taillamps with an LED accent give the car added visual width. Bland as it may be, it's a handsome little concept, though fear what would likely happen if all of the conceptual details get dumbed down for a production model.

Baby Ford Ranger and electrified Dodge Challenger? | Autoblog Podcast #569

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder. They address a couple interesting news topics, including an upcoming Ford pickup that's smaller than the Ranger, as well as a future electrified Dodge Challenger. They also opine about the new Honda Urban EV prototype that's scheduled to debut at the Geneva Motor Show. Then they talk about the cars they've been driving, including the new Subaru Crosstrek Hybrid, Volvo V60 and Audi A6. Finally, they take a question from Autoblog's recent Reddit AMA to help spend a Redditor's money.
