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 rolls out diesel Focus ST at Goodwood [w/poll]

If you're in the market for a hot hatch, there are some excellent choices at your disposal - especially if you live in Europe. But if you want a diesel, well, your choices become rather more limited. Volkswagen tends to that niche market with the Golf GTD (essentially an oil-burning version of the GTI available Stateside), but that's about the extent of it. The pleas of those looking for more diesel-burning hot hatch choices haven't fallen on deaf ears at Ford, with the Blue Oval not only rolling out a facelifted gas-powered Focus ST at the Goodwood Festival of Speed this weekend, but also a new diesel version as well.
The diesel Focus ST (which we hope and pray isn't marketed as the STD) packs a 2.0-liter turbodiesel four producing 182 horsepower and 295 pound-feet of torque to propel the oil-burning hot hatch to 62 in 8.1 seconds en route to a top speed of 135 miles per hour. With less power and only slightly more torque, that makes the diesel Focus ST considerably slower than the gasoline one, which packs 252 hp and 270 lb-ft, runs to 62 in 6.5 seconds and tops out at 154 mph, but (in a testament to how far particulate filters have come) the diesel model cuts carbon emissions by nearly a third compared to the petrol version and returns about 50-percent better fuel economy, which makes that much more of a difference in markets where diesel is already priced better than gasoline at the pump.
For buyers who wouldn't consider anything other than a diesel, it also represents 23-percent more power than the previous top-level diesel Focus. The VW Golf GTD, for reference, offers up 181 hp (just 1 horse less), 280 lb-ft (15 fewer torques) but is somehow estimated to reach 60 in a considerably fleeter 7.4 seconds.

2015 F-150 launch to curb Ford profits?

Ford is making a big bet on aluminum with its new 2015 F-150, and it's possible that the decision will hurt the company financially, at least in the short term. After earning a record $8.6 billion in 2013, the Blue Oval does not expect to set another record in 2014. According to Automotive News, that's "largely attributable to F Series," says Bob Shanks, Ford's Chief Financial Officer.
To retool for the new F-150, Ford will idle its Dearborn Truck Plant in Michigan for 11 weeks and the Ford Kansas City Assembly Plant in Missouri for 2 weeks. "3 of the 13 overall weeks occur during what normally is our summer shutdown timeframe," said Mike Levine, Ford Trucks Communication Manager, in an email to Autoblog. The extra 10 weeks will be preparing for the more aluminum-intensive construction for the trucks and will mean over 2 months of no F-150s being made. For comparison's sake, Chrysler boss Sergio Marchionne just confirmed that the 200 plant in Sterling Heights, MI will be down for 30 days to retool for the new model, but obviously there are many more F-150 production variables than for the midsize sedan.
Levine notes that Ford is already running three shifts at both plants, and says the automaker has plans to ensure that there is adequate supply of the full-size pickups during the retooling process. The company does not want to suffer a shortage of the vehicle that accounted for 31-percent of its 2013 US sales and an even bigger percentage of its profits.
