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.

2015 Ford Mustang potentially 'leaked' by Car and Driver

Few upcoming debuts have been as eagerly anticipated as the all-new Ford Mustang that's expected to debut shortly as the Mustang's 50th anniversary year approaches. Well, Car and Driver magazine would have us wait no longer as it claims to be leaking Ford's new global pony car early.
Of course what you're looking at is just as likely to be a composite rendering based on what C/D projects the new Mustang to look like, but to our eyes it looks spot on. Combining design traits from the Evos Concept with classic Mustang signatures and Ford's Aston-inspired grille treatment, C/D's images - including a complete 360-degree digital navigator - show a Mustang not only for the modern era, but also for global distribution, taking a quintessentially American car to markets its predecessors were never designed for.
Those global considerations are expected to spell the demise of the outgoing Mustang's holdout live rear axle in favor of an independent suspension, and a slight constricting of the exterior dimensions. And thanks to a separate leak, coming from a digital survey, we have apparent confirmation of what will power the new pony car. While the existing 3.7-liter V6 and 5.0-liter V8 engines will apparently carry over with only slight adjustments in output, the survey confirms a new 2.4-liter turbo four will be positioned in between them, offering slightly more power than the V6 but markedly improved fuel economy for a manageable $560 premium over base.
