VW air rule violation allegations 'stunning,' $18B fine unlikely

The big automotive news today was the US federal allegations that VW quietly and illegally installed software on approximately 482,000 diesel vehicles sold in the United States so that they would not return substandard results on government emissions tests. To say the least, this is potentially a very big deal. You can read the details of the government's allegations here. The problem seems to be with the NOx trap. Sam Abuelsamid, a former AutoblogGreen editor who is now a senior research analyst at Navigant Research's Transportation Efficiencies program, told me that there were some hints that VW's diesel emissions strategy had issues a while back. The vehicles affected by today's announcement are all equipped with the 2-liter, 4-cylinder TDI, he said. They all have the lean NOx (nitrogen oxides) trap, whereas all other current modern diesels use urea to treat NOx emissions. "When VW launched those vehicles, I went to the TDI launch program in Santa Monica and asked them if they were going to put the diesel engine into the Tiguan because that would be an ideal application," he said. "They said no, because it would be too heavy. Turns out, the NOx trap was enough to meet the emissions standards in the smaller cars, but not the Tiguan. That seems to be where the problem is, in the NOx trap. All the other big VW and Audi diesels, they use urea, just like BMW and Mercedes do." Abuelsamid added that, in California, to do an emissions test, testers don't stick a probe up the exhaust, as you would suspect. Instead, they just do a visual test to make sure nothing was tampered with and then plug a scanner into the OBD-II port to read the codes. The news today basically says that the cars were programmed to send out false codes, giving readings that testers are looking for instead of what's actually going on. "That's the background, as far as I know at this point," he said. This could be "a black eye on the auto industry." - John O'Dell Speaking at the AltCar Expo in Santa Monica just hours after the news first broke this morning, Edmunds.com's John O'Dell said the Fed's allegations were "stunning." The idea that VW might have gamed the system, he said, "underscores how important EPA clean air numbers are, that a company would allegedly stoop to this to try and meet them. Obviously, people are paying attention to that sort of thing.

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.

BMW says its diesels are above board

BMW got yanked into the riptide of the Volkswagen diesel scandal thanks to a report in Auto Bild, which Auto Bild has now clarified. On Thursday the German magazine said that when the International Council on Clean Transportation tested the X3 xDrive 2.0d, the ICCT discovered the diesel X3's tailpipe emissions exceeded the European limit by more than 1,100 percent. The key detail, though, is that apparently at no time did the ICCT find that BMW cheated on any emissions tests. No one has explained why the X3 diesel had such high emissions and the ICCT wouldn't comment on the Auto Bild report. But the mag has issued a clarification asserting that in spite of the excessive emissions, there is no evidence BMW engaged in regulatory subterfuge. Every other BMW vehicle ICCT tested was within compliance, but the organization's report from October 2014 - that no one paid attention to - found that nitrogen oxide emissions in 15 vehicles it tested averaged seven times the European limit. The brand's stock is still suffering from the taint. It dropped almost ten percent the day the report came out before rallying to close at five percent down. But on Monday BMW stock closed at 84.01 euros, and as of writing on Friday it's still trying to fight its way back above 80 euros. With so many people still just trying to find out how widespread the the issue is, and trust rather low, it's likely BMW won't be the one dragged down, fairly or not. Related Video:
