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 banned from SCCA autocrossing because of rollover risk

Autocross can be a great way to break into motorsports, especially at SCCA events that allow run-of-the-mill, street-legal vehicles to be run through the cones in parking lots across the country. But while a wide array of vehicles are eligible, not every one is. And now the Ford Fiesta has been removed from the list of qualifying vehicles in the Sports Car Club of America's Street category for solo events. The removal of the Fiesta was publicized in the latest issue of the SCCA's Fastrack News bulletin, which stated that, due to roll-over risk, Fiestas "do not meet the requirements and are to be removed" from the HS category of eligible vehicles. H Stock (or HS for short) is the lowest category of vehicles certified by the SCCA for use in sanctioned events. The disqualification applies to Fiestas from the 2011 model year onwards, and does not apply to the Fiesta ST, which remains eligible. Of course the Fiesta isn't the only model deemed ineligible for SCCA autocross events. According to Jalopnik, other small hatchbacks and crossovers including the Dodge Caliber, Fiat 500, Scion xB and iQ, Nissan Juke and Mini Countryman are also prohibited from competition. We've reached out to both Ford and the SCCA for clarification on the issue, and will issue an update if and when we receive any substantial information.

Is that the Ford GT Le Mans racer in the background of this Forza video?

Shortly after the reveal of the new Ford GT in Detroit a couple of weeks ago, Microsoft announced that it was putting the new American supercar on the cover of the upcoming sixth installment of the Forza Motorsport video game series. Now it has put out a video of the process of digitizing Dearborn's latest. Whether you're into Detroit steel (or carbon fiber and aluminum in this case), exotic supercars or video games, the video is worth a watch in and of itself. But our eyes were focused on something else. In the background of one shot (around the 1:49 mark) you can see a design board with renderings of what looks to be the rumored racing version of the GT – complete with reshaped air intakes, deeper side sills, a bigger rear wing and a central rear fin like you'd find on the latest LMP1 racing prototypes. It wouldn't be the first time we've caught wind of the prospect of the Blue Oval's new supercar going racing. We first heard of the plans last October, further reinforced in December with reports of the new GT coming to Detroit. And as we reported just a couple of weeks ago following the supercar's reveal, a return to Le Mans could be in the cards – which would be fortuitous timing, since next year will mark the 50th anniversary of the original GT40 scoring its landmark 1-2-3 finish in the 24-hour race.
