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 Fiesta ST gets worked out on the track

We're big fans of the turbocharged Ford Focus ST, and we're plenty excited that the Blue Oval will be offering a similar treatment on the smaller Fiesta here in the United States, too. We first saw the production-ready Fiesta ST five-door at the Los Angeles Auto Show last fall, and Ford has now released this video of a Euro-spec three-door ST being flung around the track.
But not just any track - the challenging Track 7 of Ford's Lommel Proving Grounds in Belgium. The course features 20 turns and plenty of elevation changes along its 2.7-mile loop, and David Put, a vehicle dynamic specialist at Ford, shows just how good the pint-sized Fiesta ST is at handling the lot, even getting the smallest ST up on three wheels every now and then.
It sure does look like a lot of fun, and makes us really eager for our chance to try this ourselves. Scroll down to see the hot little Ford getting busy.

Petrolicious pays visit to tuning sensation the Ringbrothers

We caught up with a few projects from Ringbrothers at SEMA this year: a classic Ford Mustang body rendered in carbon fiber, and a De Tomaso Pantera-based concept that made us swoon.
It's with good timing then, that our friends at Petrolicious have uploaded their newest, well-crafted mini-documentary to the expansive airwaves of the Internet. Here, we meet the brothers Ring in person - Mike and Jim - and see how they've lent they're passion for craftsmanship to their business, along with their surname. A 1964 Ford Fairlane dubbed "Afterburner" and a 1965 Mustang called "Producer" star in this show.
