A report created by European Federation for Transport and Environment indicates automakers other than those within Volkswagen Group may use software or similar technologies to skirt emissions lab tests, according to Automotive News.
The report was based on a review of date collected by the International Council on Clean Transportation, the same research group that accidentally broke the VW ‘Dieselgate’ scandal. It indicates that there are major discrepancies between lab and real-world results on several different automakers’ cars including BMW, Mercedes-Benz and General Motors’ Opel arm.
The results show that these cars may be fitted with a similar defeat device as VW’s 2.0-liter TDI car, which would detect when the car was undergoing lab emissions tests and self adjust engine settings to reduce emissions. Nico Muzi, spokesman for Transport and Environment, says VW’s violations are “just the tip of the iceberg.”
BMW has denied the allegations, telling AN its vehicles meet emissions standards both in lab and real world tests and pointing out that the original ICCT report backed this up. Mercedes-Benz and General Motors did not respond when asked for comment.
