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 Ken Block play traffic cop in ’Top Gear’ teaser

BBC is teasing a new series of 'Top Gear' starring the rally racer and Hoonigans honcho Ken Block and promising that series 25 is "coming soon." Block plays a police officer (with a Los Angeles Police Department badge, no less) in an off-road 4x4 vehicle in the 30-second clip, jumping off obstacles and tearing through dirt in an industrial area near snow-capped mountains. He gives chase to show hosts Matt LeBlanc, in a yellow Ford Mustang, Rory Reid and Chris Harris, who steers a McLaren 570S. It looks like they're having more fun that the rest of us. LeBlanc has said the next season of episodes will aim to attract a younger, more diverse audience with more comedy. Series 25 is expected to launch in spring, perhaps after the wrap-up of the second season of 'The Grand Tour.'Related Video: Celebrities TV/Movies Ford McLaren Off-Road Vehicles Performance Top Gear Ken Block

Ford F-150 pulls semi truck through snow-clogged Chicago streets

Earlier this week, the Midwest was crippled by a massive snowstorm that dumped a foot or more of powder in some areas. The result was, of course, transportation gridlock. It's a fortunate thing for this stranded semi-truck driver, then, that a Ford F-150 EcoBoost stumbled upon him. Despite a tow rating of just over 11,000 pounds, the four-wheel-drive, turbocharged pickup managed to dislodge the big rig from a snow-covered street. Of course, the Ford didn't get the semi moving all on its own – watch the video towards the end and the semi was quite clearly spinning its rear tires. Still, it's an impressive feat that we've little doubt F-Series fans are celebrating. Related video:
