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.

Highlights and standouts from the 2015 LA Auto Show

This year's LA Auto Show has been packed with interesting debuts and fascinating industry trends. The Autoblog team is on the scene to examine all the new metal, and Senior Editor Greg Migliore has some show highlights for us in the video above. In particular, the new Fiat 124 Spider and Honda Civic Coupe stand out as important debuts. The Fiat is based on the excellent Mazda Miata, with a turbocharged 1.4-liter engine and revised styling. The Civic Coupe is a striking redesign of an extremely popular and important model for the company. And the restyled Ford Escape looks more like its bigger brother, the Explorer. There's this an much more in our video above. Watch it and let us know what you think – and look for more LA Auto Show coverage coming soon.

Ford F-250 boots Cadillac Escalade from atop thieves' most-wanted list

The Ford F-Series has been America's best-selling truck for decades, but along with the good comes the bad, apparently. In addition to being popular with consumers, the Highway Loss Data Institute notes that the F-Series Super Duty has risen in popularity among thieves. Based on its new study, the four-wheel drive crew cab F-250 Super Duty has topped the list for the country's highest rate of insurance theft claims, knocking the Cadillac Escalade from the top spot - a distinction the luxury SUV has held since this annual report was first established in 2003.
To reach its findings, HLDI looks at theft data from the previous three model years (in this case 2010-2012) to determine the frequency of claims for a particular make and mode,l as well as the average payment per claim. As the report points out, the claims aren't always for the theft of the entire vehicle - they can include components (say, wheels and tires) or property taken from the vehicle. At seven claims per 1,000 insured vehicles, the F-250 is six times more likely to suffer a theft claim than the average vehicle.
The Cadillac likely dropped from the top of the list to sixth due to additional theft-prevention features including a steering wheel lock and inclination sensor for the alarm, but GM's other fullsize trucks and SUVs still occupy eight of the list's 10 spots. Some of the least stolen vehicles with below-average loss payments include the Lexus HS250h, Hyundai Tucson, Honda CR-V and Dodge Journey. Head on over to the HLDI's website for the full list that shows the most and least popular vehicles among thieves from 2010 through 2012.
