Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

Mazda recalls 193k CX-9 crossovers over corroded suspension

An issue with the suspension on the CX-9 has prompted Mazda and the National Highway Traffic Safety Administration to recall 193,484 vehicles across the United States. The campaign specifically affects units from the 2007-2014 model years, manufactured between October 24, 2006, and December 28, 2013. In those affected vehicles, the ball joints in the front suspension may corrode due to water leaking into the fitting. According to the statement below, if the ball joint rusts, the front lower control arm could separate, resulting in a loss of steering control. And needless to say, that could lead to a crash. To repair the issue, Mazda will have to replace both the left and right lower control arms, and will naturally do so free of charge, but will undertake the repairs in stages. First, owners of the affected vehicles will receive a notification that a recall campaign is under way. Then they'll get a second letter when the parts are ready and they can bring their vehicles into their local dealers. The company will start first with 2007-09 vehicles, specifically those registered in the snowy states of the Northeast and Midwest. Specifically: Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington, DC. (Oddly, states in the the western portion of the Midwest, as well as the Rocky Mountains and the Pacific Northwest, were not included in that initial phase. Nor was Alaska, for that matter.) After that they'll call in 2010-14 models in the same states before undertaking repairs on vehicles in other areas to the west and south.

The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting. CONSEQUENCE: Over time, the ball joint corrosion may result in the front lower control arm separating from the ball joint, causing a loss of steering control and increasing the risk of a crash.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
