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 Mustang GT500 successor spied near SVT

Details about the next-gen Ford Mustang are scarce, and there's even less information out there about the upcoming replacement for the Shelby GT500. Previously rumored to drop the Shelby name and wear the GT350 moniker, the highest-performance Mustang has just been spotted testing near Ford's SVT operations.
Despite being cloaked in heavy camouflage, we can instantly tell this prototype is different from other Mustang spy shots we've seen in the past. Aside from the Shelby-spec wheels, quad exhaust outlets (previous spy shots show only two) and beefier brakes, this car also has air intakes on the hood and front fenders. These elements help to neither prove nor dismiss rumors that the next SVT Mustang will be naturally aspirated. It also looks like Ford is may be planning some changes to this car's rear suspension, as there is some extra camouflage added beneath the rear end of this prototype.
As a bonus, these spy shots also give us our first look inside the new Mustang, revealing a new steering wheel (with more buttons) and a glimpse of the dual-pod instrument gauges. Check out past spy shots of the 2015 Mustang showing off its new face and driving around town.

2015 Ford Mustang EcoBoost flogged and analyzed by Ignition

Aside from the way it looks and perhaps its independent rear suspension, the biggest bit of news on the 2015 Mustang may be the inclusion of its 2.3-liter, turbocharged four-cylinder engine. That blown mill marks the first time since the Mustang SVO of the '80s that a turbo has been fitted under the engine of Ford's pony car.
The Mustang EcoBoost is the subject of the latest episode of Ignition from Motor Trend, giving us a great look at the technical, nitty-gritty side of the turbocharged coupe. Covering it from bow to stern, host Carlos Lago walks us through the boosted Ford before taking to the track for some driving impressions, with particular praise given to the low-end grunt of the 2.3-liter mill.
Check out the full video and then let us know which 2015 Mustang has your interest piqued the most - the EcoBoost four, the 5.0L V8 or the entry-level V6.
