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.

Consumer Reports says Toyota, Ford, Honda and Chevy are big winners in brand perception survey

According to Consumer Reports, the automotive brands that stand out in the minds of car buyers are, in order: Toyota, Ford, Honda and Chevrolet. This news comes after the magazine polled its readers, asking them to take into account vehicle quality, safety, performance, value, fuel economy, design/style, and technology/innovation - which are the factors that car shoppers are most influenced by.
It's important to note that this award is only about perception. In other words, it's perceived quality, not actual quality. "Often, perception can be a trailing indicator, reflecting years of good or bad performance in a category, and it can also be influenced by headlines in the media," said Jeff Bartlett, Consumer Reports deputy automotive editor.
The brand that made the biggest jump in perception amongst Consumer Reports readers is Tesla, which posted an impressive 47-point gain to finish in fifth place. Subaru is also notable for finishing in the top 10, despite being one of the smaller manufacturers doing business in the US.

Weekly Recap: Auto execs face life in prison for recall delays under proposed legislation

The stiff punishments are part of broader transportation legislation, but clearly McCaskill has automakers in her sights.
Missouri Senator Claire McCaskill threw down the gauntlet this week, proposing a bill that could send auto executives to prison for life if they were found to have delayed a recall. She also wants to eliminate the limit for fines for auto safety violations, which are currently capped at $35 million.
