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.

Watch this Ford F-150 SVT Raptor fly like an eagle [UPDATE]

The Ford F-150 SVT Raptor is a very capable truck right out of the box, but "capable" has never translated into "invincible." Just ask the owner of the machine in this video. In it, the driver gets frisky with an aggressive jump with plenty of speed on his hands. The result is enough air to make Vaughn Gittin Jr. blush. As always, it's not the launch that's painful, but the re-entry. Gravity eventually asserts its dominance over the $43,630 pickup in a big way, and when it comes crashing down, it does so with a vengeance.
The impact was hard enough to set off both the alarm and multiple airbags inside the cabin. It's unclear if anyone was injured in the stunt, but we certainly wouldn't be surprised to hear that was the case. You can check out the stunt in the video below, and remember, when in doubt, back out of the throttle. Be warned, there may be some explicit/NSFW language in the clip.
UPDATE: Second video added with an even better look at the jump added below.

Texan finds creative way to clear highway fast lane

Few things are as infuriating as someone driving slow in the fast lane. A Jeep driver from Texas found himself in just such a predicament near Fort Worth, and came up with a creative way to urge the offending lane-blocker to get a move on. Machine, a YouTuber and off-road enthusiast from the Lone Star State, posted some dashcam footage to his account back in March which showed him stuck behind a slow driver. He was attempting to pass a slow-moving bobtail Peterbilt tractor when he got hung up by a white Ford Econoline squatting in the passing lane. On his YouTube page, Machine stated that the van, which apparently belonged to a plumbing company, was traveling along between 60 and 70 miles per hour along a stretch of highway with a stated speed limit of 70 mph. Confronted with the slow-moving van blocking the left lane, and traffic in the right lane, Machine called the number on the back of the Econoline and politely asked him to get out of the way. In the Econoline, the passenger picked up and was momentarily confused as Machine asked him to ask his driver to move out of the lane and let traffic pass. The van sped up, passed a tractor-trailer, and got out of the way, much to the relief of the traffic behind him. According to CBS news, 38 states have laws on the books to punish slow drivers squatting in the passing lane. In five of those states, the fine is upwards of $1000, and 22 states classify it as a misdemeanor.
