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 announces first non-pursuit-rated police car ever

Ford announced its first non-pursuit-rated Police Interceptor ever, based on the Taurus, which employs the smaller 2.0-liter EcoBoost four-cylinder engine in place of similar pursuit-rated Police Interceptors powered by naturally aspirated 3.5-liter and 3.7-liter V6s and the top-spec 3.5-liter EcoBoost V6. Officially called the Special Service Police sedan, the car was commissioned at the request of law-enforcement agencies that desire a more fuel-efficient vehicle for detectives, administrators and campus police, who don't necessarily need pursuit-rated vehicles.
The 2.0-liter EcoBoost engine produces 240 horsepower and 270 pound-feet of torque, but more importantly, it allows the SSP sedan to achieve somewhere in the neighborhood of 22 miles per gallon city and 32 mpg highway, which are the civilian 2.0-liter Taurus' official EPA ratings. Ford estimates that the SSP sedan will get 20 mpg city, 30 mpg highway and 23 mpg combined, with the help of Active Grille Shutters that open to allow more cooling air through to the radiator, or close to optimize aerodynamics and fuel economy. Those numbers compare favorably to the discontinued Crown Victoria-based Interceptor's 14 mpg city and 21 mpg highway and the newer Taurus-based cars equipped with V6s, the most fuel efficient of which gets 18 mpg city and 26 mpg highway.
If it was driven 90,000 miles over the course of three years, a 2.0-liter SSP sedan would save law enforcement agencies $5,042.92 versus the Crown Vic, Ford estimates. The EPA is expected to post official fuel-economy numbers for the SSP sedan in December. Until then, read the press release below for more information.

Is Tesla's next project an F-150 competitor? [w/poll]

What's the future look like for Tesla after it launches the Model X CUV and possibly a smaller, sub-Model S sedan? Would you believe a pickup truck? Yes, Tesla could be looking to use its EV know-how to take the fight to Ford and the F-150, based on comments made by company founder Elon Musk.
"If you're trying to replace the most gasoline miles driven, you have to look at what people are buying," Musk said during an impromptu Q&A session following a speech at Business Insider's Ignition conference. "[The F-150 is] the best selling car in America. If people are voting that's their car, then that's the car we have to deliver."
And while the idea of electric pickup may sound kind of absurd to some, Musk makes a very valid point - if Tesla's goal is to replace gas miles with electrical miles, it simply can't afford to ignore pickups.
