Major automakers urge Trump not to freeze fuel economy targets

WASHINGTON — Major automakers are telling the Trump administration they want to reach an agreement with California to avoid a legal battle over fuel efficiency standards, and they support continued increases in mileage standards through 2025. "We support standards that increase year over year that also are consistent with marketplace realities," Mitch Bainwol, chief executive of the Alliance of Automobile Manufacturers, a trade group representing major automakers, will tell a U.S. House of Representatives panel on Tuesday, according to written testimony released on Monday. The Trump administration is weighing how to revise fuel economy standards through at least the 2025 model year, and one option is to propose freezing the standards through 2026, effectively allowing automakers to delay investments in technology to cut greenhouse gas emissions from burning petroleum. The National Highway Traffic Safety Administration has not formally submitted its joint proposal with the Environmental Protection Agency to the White House Office of Management and Budget for review. Even so, last week, California and 16 other states sued to challenge the Trump administration's decision to revise U.S. vehicle rules. Auto industry executives have held meetings with the Trump administration for months and have urged the administration to try to reach a deal with California even as they support slowing the pace of reduction in carbon dioxide emissions that the Obama administration rules outlined. One automaker official said part of the message to President Donald Trump at a meeting on Friday will be to consider California like a foreign trade deal that needs to be renegotiated. Automakers want to urge him to get automakers a "better deal" — as opposed to potentially years of litigation between major states and federal regulators. On Friday, Trump is set to meet with the chief executives of General Motors, Ford, Fiat Chrysler and the top U.S. executives of at least five other major automakers, including Toyota, Volkswagen AG and Daimler AG, to talk about revisions to the vehicle rules. Senior EPA and Transportation Department officials will also attend. Environmental groups are eager to keep the rules in place, saying they will save consumers billions in fuel costs. A coalition of groups plans to stage a protest outside Ford's headquarters in Michigan.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.
