BMW has reiterated that its exhaust treatment systems on its diesel engines are active whether rolling on the test bench or driving on the road.
Numerous automakers are under the microscope now that Volkswagen has admitted to cheating on diesel emissions tests and German publication Auto Bild is alleging that road tests conducted by the International Council on Clean Transportation (ICCT) found the BMW X3 20d xDrive diesel emitted more than 11 times more nitrogen oxide than the legal limits of Euro 6. BMW has said that two studies carried out by the ICCT have confirmed that the BMW X5 and 13 other BMW vehicles comply with the legal requirements and no discrepancies have been found in the X5 between lab testing and field testing.
The company is not familiar with the test results that Auto Bild is mentioning and has contacted ICCT for clarification on the tests that were carried out with the X3 diesel.
BMW also shared some sales data on its diesel vehicles, saying that they account for 38 percent of vehicles sold worldwide last year. In Europe, 80 percent of BMW models sold were equipped with a diesel engine while in the U.S. it’s only six percent, equaling approximately 20,000 vehicles in the U.S.
Update: BMW has released an extra statement saying that Auto Bild has published a clarification of its article saying: “No evidence of emission manipulation by BMW… The values mentioned in the document were only generated in a single, hour-long road test. Auto BILD has no access to the details of the test trail, which might explain the discrepancies to the test cycle NEDC.”
