Automakers want to stop the EPA's fuel economy rules change, and why that's a shortsighted move

With a Trump Administration looming, the EPA moved quickly after the election to propose finalizing future fuel economy rules last week. The auto industry doesn't like that (surprise), and has started making moves to stop the EPA. Ford CEO Mark Fields said he wanted to lobby Trump to lower the standards, and now the Auto Alliance, a manufacturer group, is saying it will join the fight against cleaner cars. The Alliance represents 12 automakers: BMW, Fiat Chrysler, Ford, GM, Jaguar Land Rover, Mazda, Mercedes-Benz, Mitsubishi, Porsche, Toyota, VW, and Volvo. Gloria Bergquist, a spokesperson for the Alliance, told Automotive News that the "EPA's sudden and controversial move to propose auto regulations eight months early - even after Congress warned agencies about taking such steps while political appointees were packing their bags - calls out for congressional action to pause this rulemaking until a thoughtful policy review can occur." The EPA was going to consider public comments through April 2017, but then said it would move the deadline to the end of December. That means that it can finalize the rules before President Obama leaves office. The director of public affairs for the Consumer Federation of America, Jack Gillis, said on a conference call with reporters last week when the EPA originally announced its decision that it is unlikely that President Trump will be able to roll back these changes. Gillis also said on the same call that any attempt by the automakers to prevent these changes would be history repeating itself. "These are the same companies that fought airbags, and now promoting the fact that every car has multiple airbags," he said. "These are the same companies that fought the crash-test program, and now are promoting the crash-test ratings published by the government. So, it's clear that they're misperceiving the needs of the American consumer." There are more reasons the Allliance's pushback is flawed. Carol Lee Rawn, the transportation program director for Ceres, said on that call that the automotive industry is a global one, and many automakers are moving to global platforms to help them meet strict fuel economy rules around the world.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

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.
