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:

Ford F-100 'Snakebit' shown off by Gene Simmons and Shannon Tweed at SEMA

Ford, along with KISS bassist Gene Simmons and his wife, Shannon Tweed, used SEMA as a backdrop to pull the covers off Snakebit, a 1956 Ford F-100 pickup truck that's been updated with Shelby Mustang-derived styling bits and a 5.4-liter supercharged V8 engine. All 550 horsepower are funneled through a six-speed manual gearbox to the rear wheels.
Underneath the custom bodywork sits a chassis that's been stretched five inches and a bed widened and bedecked with billet machined pieces that are supposed to look like wood. The 20-inch rear and 18-inch front wheels ape those of past Shelby Mustang models. The interior is swathed in two-tone leather with a bench seat designed to look - try to act surprised - like a Shelby Mustang.
Like what you see? Bidding for the truck will take place in 2014 at an unspecified Barrett-Jackson event (we'd assume Scottsdale). Proceeds will be used to help build a children's hospital in Saskatoon, in the province of Saskatchewan, where Ms. Tweed grew up. See the high-res gallery above and the press release down below for more.
