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 Focus sedan shows its fresh face in New York

That handsome fellow you see above is the 2015 Ford Focus sedan. We liked the looks of the 2014 Focus, and the updates for 2015 only improve things to our eyes, with the adoption of the Aston Martin-inspired grille that has been permeating Ford's lineup these last few years. Sweeping, slightly bulbous headlamps join a revised, more demure lower grille opening to round out the styling updates up front. The rest of the car's look is just slightly massaged, including new taillamp clusters that look much like they did last year.
New for 2015 is the availability of Ford's 1.0-liter three-cylinder EcoBoost engine, mated exclusively to a six-speed manual transmission. There's also a new SE Sport Package that adds more aggressive suspension tuning, paddle shifters (when equipped with Ford's six-speed dual-clutch automatic) and a few body kit bits and pieces. Rounding out the mechanical changes are an updated electronic steering rack that promises better feel, suspension tweaks to make the ride more comfortable and some software updates designed to make the dual-clutch gearbox better behave itself.
In addition, inside there are a few interior upgrades, as well as some added comfort and safety tech that includes available blind-spot detection and lane-keeping assist, along with other more incremental changes that all add up to a better vehicle. We suggest you check out the official press release below for all the details, but not before scrolling through our image gallery of live shots above.

Ford Transit gets outfitted for prison duty

Between the Taurus-based Police Interceptor, the Explorer-based Police Interceptor Utility and the F-150 and Expedition special service vehicles, Ford has no lack of offerings for law enforcement. And now it has one more in the form of the new Transit PTV.
Based on the fullsize Transit van, the Prisoner Transport Vehicle can move as many as 12 prisoners in three separate compartments between detention facilities. Created in collaboration with Pennsylvania-based Havis Prisoner Transport Solutions and with input from Ford's Police Advisory Board, the Transit PTV takes advantage of the Transit's considerable configuration options that include three roof heights, two wheelbases, three lengths and four body-styles - not to mention engine options that include the flex-fuel 3.7-liter V6, 3.5-liter EcoBoost and 3.2-liter Power Stroke diesel.
"Transit PTV is the latest example of Ford's deep commitment to helping provide law enforcement agencies with capable vehicles. This concept proves Transit is upfit-ready and designed to Built Ford Tough standards," said Jonathan Honeycutt, Ford police marketing manager. "Many Police Advisory Board members have had the chance to drive this vehicle and they are excited about it. This new vehicle is tough, smart and efficient - ideal for the needs of law enforcement agencies."
