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.

Here's the new face of the Ford Ranger

Ford Asia Pacific has put a teaser video on YouTube showing off details on the 2015 Ranger pickup, and at the end we get a quick glimpse of the whole truck. This is the T6 Ranger that we still don't get in North America, but that shares its underpinnings with the Everest SUV recently introduced at the Asia-Pacific Economic Cooperation forum. The Ranger gets a chunkier front end than the Everest, identified by its grille with three floating slats, reminiscent of designs on the previous F-150, and a less-stylized lower front bumper. Ford says it will be smarter, safer, smoother and stronger, but we'll have to wait for its reveal to find out what that means. Meanwhile, you can admire its new looks in the video below.

Entry-level F-150 now offers SuperCrew, Sport Package

Ford has made a few notable tweaks to the lower end of its F-150 lineup, giving customers a more affordable version of the four-door SuperCrew body style. The popular SuperCrew could previously only be had on XLT models and above, but Ford has announced that 2014 F-150s with the base STX trim can get the more versatile body.
The STX SuperCrew brings the price of a four-door F-150 down from $34,525 to $33,145. Like the XLT SuperCrew, the STX will be available with the choice of a 5.5- or 6.5-foot bed, while a 5.0-liter V8 can replace the base 3.7-liter V6 for $4,425. Ford has not released pricing on the different bed lengths yet, but opting for the 6.5-foot bed on the XLT raises the price $1,240 and forces buyers into the 5.0-liter V8. We'd expect a similar arrangement on the STX.
The other big news for fans of affordable pickups is the addition of an STX Sport Package on the base-level truck. It adds 20-inch wheels, black exterior accents, black-and-gray cloth seats and decals on the truck's box. The Sport Package is available on all three of the STX's body styles, with Ford listing the price as $980 with current discounts.
