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 Focus EV's slow sales trigger massive incentives

The Detroit News reports Ford is having real trouble moving its new Focus Electric. As a result, the automaker is offering substantial incentives in an attempt to lure in more buyers. How substantial? Try $10,750 off of a three-year lease. What's more, the EV can now be had for $37,995 ($2,000 less than its original base price) on top of an additional $2,000 cash discount to buy the EV outright - or you can opt for 1.9-percent financing if you work through Ford Motor Credit. None of which factors in various potential government incentives. Last year, Ford managed to sell a paltry 685 of the 1,627 Focus EV hatchbacks it built.
Ford isn't alone in trying to woo more buyers to its EV effort. Nissan cut the price of its Leaf by a whopping 18 percent for 2013, now down to $28,800 and built in the USA. The move followed the automaker's substantial incentives in 2012.
If you want a Focus Electric, you can now apparently get your hands on one for as little as $285 per month with $930 due at signing for a 36-month lease with 10,500 miles per year.

Ford Shelby GT350 Mustang is a lean, mean, Z/28-fighting machine [w/video]

If there's one thing you can count on, it's that the renewed rivalry between the Ford Mustang and Chevrolet Camaro will never, ever cease. For every version of Ford's pony car, there's an equally potent Chevrolet. And so with the debut of the Camaro Z/28 earlier this year, Ford has responded with a track-focused 'Stang of its own, resurrecting the Shelby GT350 name.
It looks to be a fine piece of work, this Mustang, with power coming from a naturally aspirated 5.2-liter V8 that will produce "more than 500 horsepower" and "above 400" pound-feet of torque. That grunt runs to the rear wheels via a six-speed manual transmission, and a Torsen limited-slip differential keeps everything in line.
But that's hardly the most impressive piece of the GT350 puzzle. Ford has increased the Mustang GT's chassis stiffness for duty here in the Shelby, and the coupe employs MagneRide damping which automatically adjusts based on road conditions and driver inputs. It's a first both for the Blue Oval and for the segment. And speaking of firsts, the GT350 uses a flat-plane crankshaft - something Ford has never included in a production V8 before.
