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.

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 board OK with Mulally stepping down earlier

Ford's board is open to CEO Alan Mulally stepping down before his planned departure in 2014, inside sources are telling Reuters. Ford's plan of succession, aside from who would be his actual successor, has been something approaching common knowledge - the 68-year-old former Boeing exec had plans to stay through 2014. This was recently confirmed by Mulally himself on Bloomberg Television and in Automotive News.
Motivation for the about-face comes from what Reuters calls a "growing confidence" in the current crop of Ford execs, led by Mark Fields. Fields, Ford's current chief operating officer, has been tipped as Mulally's ultimate successor, although he's far from the only person with eyes on Ford's top job. Normally, Ford's board saying they're open to an executive, that's done very well for the company, stepping down early would be nearly unremarkable. It's the timing of this announcement, though, that makes this a big piece of news.
Recently, Mulally has been the subject of rumors that he's interested in taking the CEO position at tech giant Microsoft. The Redmond, Washington-based company's CEO, Steve Ballmer, told the media in August that he'd be retiring in a year's time. The fires were stoked when tech website AllThingsD speculated that Mulally would take the top spot, despite denials from the man himself. Could Ford's current boss become the new top dog at Microsoft? Will Mark Fields replace him? Could recently departed Renault exec Carlos Tavares land at Ford in some capacity?
