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.

2013 Ford F-150 Limited

The Ford F-150 received yet another new model for the 2013 model year, the Limited trim, bringing the ways you can order this country's most popular vehicle to a grand total of 10. There really is an F-150 to suit any need now, and the Limited variant slots in at the very top of the range, above the already pampering Platinum model.
While normally I would admit that I'm the least-appropriate person to test a pickup, the fact that this particular trim places a much higher premium on luxury than anything with a bed and Blue Oval badge before it means that I don't need the workman chops of a skilled tradesman to judge how well this truck meets its true aim.

Ford Focus ST, Fiesta ST buyers to get free Octane Academy driving school

The Ford Focus ST and Fiesta ST have created plenty of excitement in the sport compact segment, and Ford is looking to make sure that owners are driving and enjoying their cars to the best of their abilities. As an added bonus for buying one of these sporty hatchbacks, Ford will provide a complimentary ST Octane Academy session to be held at the Miller Motorsports Park in Utah.
Attendees will be responsible for travel and lodging, but Ford will provide the driving school free of charge. Included in this two-day trip, ST owners will get class instruction and driving instruction in prepped Focus ST and Fiesta ST models on the track and autocross course. Some karting action will also be involved as will a tour of Ken Block's Hoonigan Racing headquarters located nearby. If this doesn't sound like enough fun, there is also an optional day of activities that includes some more track time in a Mustang GT and off-road instruction in an F-150 SVT Raptor.
Ford told us that those who have already purchased a Focus ST or Fiesta ST will still be able to attend the performance driving school, but the press release, which is posted below, makes it sound like it applies to original owners only. Ford has yet to announce its schedule for the ST Octane Academy or prices for additional activities or guests.
