It is still a possibility that other automakers cheated on diesel emissions tests.
While we’re all aware that Volkswagen has cheated on diesel emissions tests, a German government committee is looking to retest 30 cars that show “inexplicably high CO2 emissions.” The country originally tested 53 diesel cars for illegal software like the defeat device Volkswagen used, and looks to revisit 30 of those vehicles after the initial round of testing. The German transport ministry didn’t elaborate on which cars will be retested or which automakers produce them.
Last November, however, the KBA motor transport authority did say it was testing cars from the Volkswagen Group, Ford, Opel, BMW, Mercedes-Benz, Fiat, Renault, Peugeot and Toyota. The committee plans to present a CO2 report following the results of these tests, according to a spokeswoman from the German transport ministry.
So far, the KBA has found that only the Volkswagen Group used a defeat device, but it is investigating and considering other techniques automakers may have used to tweak engine performance that results in high emission levels outside test conditions.
