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 to announce Mulally retirement, Fields CEO as early as May 1

Ford CEO Alan Mulally may be about to announce his long-rumored retirement from the Blue Oval, according to a pair of insiders who spoke to Bloomberg. An official statement on the succession could arrive as soon as May 1. Chief Operating Officer Mark Fields is rumored to step up as the new CEO. The company is said to be readying the announcement soon to ensure an orderly transition of power, according to the insiders.
Mulally's retirement from Ford has been a hot topic for a while. He was seriously rumored last year to be leaving the automaker to take over as the CEO of Microsoft. The board even said at one point that it was okay with them if he stepped down early. However, the CEO maintained he would stay with the business through at least the end of 2014. Fields has been rumored as a frontrunner to take over the top spot at the company since he was promoted to COO.
For the moment, Ford isn't officially confirming any of these plans. "We don't comment on speculation. We do have succession plans in place for our key leadership. We take succession planning very seriously," said Susan Krusel, Ford Global News Manager, to Autoblog.

2015 Ford Focus

Sitting down at the pre-drive briefing with Ford engineers ahead of sampling the refreshed 2015 Focus, water bottles clinked as we wet our whistles before Q&A. While pouring a glass, we noticed something stamped on the bottle label: "1L." One liter. We were palming the exact displacement of the EcoBoost engine our group was about to drive. This was undoubtedly coincidence (such bottles litter every conference and dinner table in Europe) but it served to drive home just how small the total swept volume of Ford's wunderkind powerplant really is. It's tiny.
Of course, this isn't our first run-in with the little triple - we've sampled its turbocharged charms before in Ford's smaller Fiesta. At that time, we found it had plenty of poke for the subcompact, but the larger C-segment Focus carries around another 450 pounds or so and pushes a wider profile through the air. Would the three-cylinder have the stuffing to make the most of the Focus' athletic chassis, or would it be a letdown? Would it be the same as it was when we tested it in a Euro-spec Focus a couple of years ago? There was nothing left for it but to head out on the bucolic roads surrounding Versailles the day after the Paris Motor Show and find out for ourselves.
