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.

2016 Ford Police Interceptor Utility shows up for duty in Chicago

The latest upgrade for the 2016 Ford Police Interceptor Utility is all set to patrol the Windy City's streets with its debut at the 2015 Chicago Auto Show. On the outside, the revised Ford police vehicle looks basically the same as the recently refreshed Explorer with a new grille and redesigned headlights. Inside, there's a restyled steering wheel and center console. Unlike the civilian model, though, the PI Utility gets heavy-duty brakes, a more robust cooling system, reinforced subframe mounts and larger diameter suspension springs for more strength. Under the hood, police forces get to choose between either a 3.7-liter V6 with 304 horsepower and 279 pound-feet of torque or a 3.5-liter EcoBoost V6 with 365 hp and 350 lb-ft of twist. Regardless of powertrain, these 'utes feature a six-speed automatic transmission and all-wheel drive. The transmission includes the awesome-sounding Pursuit Mode feature that switches over to more aggressive shifts when it detects harder driving to properly stop crime. Related Video:

2015 Ford Expedition

While the tide of bigger-is-better SUVs has been in recession since, well, the recession, fullsize utes are still very much with us. Conservative creatures that have been loathe to evolve, fullsize SUVs nonetheless remain enduringly popular among large families, livery customers, and anyone with lots of friends, relatives, and toys to tug around. With respect to Toyota and Nissan, the only players that really matter in the segment are the new-for-2015 Chevrolet Tahoe/Suburban, the GMC Yukon/Yukon XL, and this truck: the Ford Expedition, the latest evolution of which we just drove for the first time at a press preview in West Virginia.
Unlike the General Motors utilities, the standard Expedition and the long-wheelbase Expedition EL are not all-new, but rather are heavily refreshed versions of the same basic truck Ford started selling way back in 2007. The front fascia is where most of the exterior update happens for 2015, with a new three-bar grille design, halogen projector headlamps, and new bumper design with available LED foglamps. Despite all the new bits, the facelift breaks exactly zero ground in terms of design; in fact, it already looks dated, and will only look older once the macho 2015 F-150 bows later this year. Even less has changed out back, where the tailgate gets a wide chrome band spanning the taillamps and a new chrome exhaust tip. Other exterior changes are generally limited to colors and an all-new wheel lineup that includes a gleaming set of six-spoke 22-inch polished wheels on high-end models.
Speaking of high-end models, a new Platinum trim is positioned above the cowboy-spec King Ranch model for 2015. Both the Platinum and King Ranch get their own color combos and exterior trim finishes (satin metal for the Platinum, chrome everywhere and ginormous badges for the King Ranch) and posh, leather-lined interiors with their own aesthetic. The Expedition family also now includes a price-leading XL model, as well as XLT and Limited grades.
