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.

Xcar flogs the 2015 Ford Focus ST

There's an inevitable dilemma that practically every auto fan eventually faces, at least other than Jay Leno and Jerry Seinfeld, and that's the tradeoff of performance, practicality and perhaps most importantly, money. Parking the fabled supercar in the garage might be the wish, but for most folks bigger responsibilities – like a family – just don't allow that dream to be a reality. In the view of XCar Films, this intersection of needs and wants is where vehicles like the latest Ford Focus ST provide a fantastic compromise between exciting driving and everyday practicality. Xcar hops into Ford's recently refreshed European hot hatch to illustrate its abilities as both a hauler for the small family on the move and for the driver who just wants to go. The Blue Oval left the powertrain alone for the ST's update, but sharpened the exterior styling, revised the interior and retuned the front suspension and steering. Being realistic, no one is ever going to get behind the wheel of the Focus ST and mistake it for a Porsche, but that's not really the point. Instead, buyers get to put a smile on their face from time to time and still maintain life's other responsibilities.

Justin Bell makes a horrible policeman

If you're wondering what type of person makes a good police officer, it seems a racecar driver doesn't. Let us rephrase that: Justin Bell, a racecar driver and the host of Motor Trend's World's Fastest Car Show, recently got behind the wheel of a 5.0-liter Ford Mustang police car with Sergeant Daniel Shrubb, co-founder of DRAGG (Drag Racing Against Gangs and Graffiti), and proved that his high-performance-driving skillset is a bit too aggressive for police duty.
While it's easy to get carried away in a Mustang GT, a patrol car driver must maintain some sort of restraint while pursuing a criminal, so as not to come off as a reckless driver to the public. We'll admit, some pursuit techniques are counter-intuitive to performance driving (stay off the gas in a lane-change exercise?), but Bell's judicious use of the handbrake can't be normal procedure.
