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.

U.S. tariff threat hits European automakers' stocks

FRANKFURT, Germany — A U.S. warning that it may introduce tariffs on foreign auto imports hit shares in German carmakers BMW, Daimler and Volkswagen on Thursday, which together have a more than 90 percent share of North America's premium car market. Washington said on Wednesday it had launched an investigation into whether car and truck imports are a national security issue due to signs they had damaged the U.S. auto industry. That could lead to new U.S. tariffs — up to 25 percent — similar to those imposed on imported steel and aluminum in March. BMW and Daimler shares fell as much as 3.1 percent in early Thursday trading, while Volkswagen's dropped as much as 2.5 percent. "(U.S. President) Donald Trump is obviously not thinking about how to prevent a trade war. Import duties on cars would be a nightmare for the German auto industry and would lead to a massive sales impact," said Thomas Altmann at Frankfurt-based asset manager QC Partners. BMW on Thursday condemned the move to consider tariffs. "The BMW Group is committed to free trade worldwide. Barrier-free access to markets is therefore a key factor not only for our business model, but also for growth welfare and employment throughout the global economy," it said. Daimler, which makes Mercedes-Benz cars, and Volkswagen, which makes upmarket Audis and Porsches, were not immediately available for comment. German carmakers produced 804,000 cars at local factories in the United States and exported 657,000 German-made cars into North America last year, according to German auto industry association VDA. China took pains on Thursday to welcome German firms and investments, with Premier Li Keqiang talking up relations after a meeting with German Chancellor Angela Merkel. BMW and Mercedes have expanded production capacity in the United States, but BMW, Audi, Volkswagen and Daimler have also invested billions to build new factories in Mexico in the hope of selling locally produced cars into the United States. German carmakers hiked vehicle production in Mexico by 46 percent to 620,000 cars last year, while production levels inside the United States fell by 6 percent to 804,000 cars because of a shift to Mexico, according to the VDA. BMW has its biggest factory worldwide in Spartanburg, South Carolina, and is the largest vehicle exporter among all the carmakers in the United States measured by value of goods exported. More than 70 percent of BMW's U.S.-made cars are exported.

French probe alleges 2 million PSA cars had engine cheats

PARIS — A French investigation into alleged emissions cheating by PSA Group found that suspect software had been used on almost 2 million vehicles sold by the maker of Peugeot and Citroen cars, Le Monde reported on Friday. Paris-based PSA denies any use of fraudulent engine software, a spokesman said in response to the newspaper report, which sent PSA shares sharply lower. The stock was down 4.4 percent at 17.78 euros as of 1019 GMT. So-called "defeat devices" restrict exhaust output of toxic nitrogen oxides (NOx) under regulatory test conditions while letting emissions far exceed legal limits in real-world driving. In February, PSA became the fourth carmaker to be referred to French prosecutors by the country's DGCCRF watchdog over suspected emissions test-cheating, after Volkswagen, Renault and Fiat Chrysler. PSA's engineering chief acknowledged at the time that emissions treatment in the group's diesels was deliberately reduced at higher temperatures to improve fuel efficiency and carbon dioxide (CO2) emissions in out-of-town driving, where NOx output is considered less critical. According to Le Monde, an internal PSA document obtained by DGCCRF investigators includes discussion of the need to "make the 'defeat device' aspect less obvious and visible." However PSA insists there is nothing fraudulent or illegal about its engine calibrations. "PSA denies any fraud and firmly reaffirms the pertinence of its technology decisions," the company said on Friday.
