The Federal Motor Transport Authority (KBA) of Germany decided to widen its investigation on diesel models to 23 brands in total.
According to a report from Reuters, more than 50 models from 23 German and other car makers will be tested on suspicion of manipulating their nitrogen oxide emissions of their diesel engines.
KBA said that they decided to investigate other brands’ diesel models after Volkswagen’s admission of manipulating the emission tests of several of its own diesel vehicles but also after verified indications from third parties that showed “unusual pollutants emissions”.
The German authority has begun the investigation since the end of September, comparing emission results in a laboratory with readings taken from portable meters in real-life tests, with two-thirds of the measurements already taken. KBA has yet to announce which brands and models are under this investigation.
Car makers and the Federal Motor Transport Authority are now in talks about “partly elevated levels of nitrogen oxides” found in raw data from the investigated models, KBA said in their statement.
Many industry experts have indicated since the first reveal of VW’s “Dieselgate” scandal that it is highly unlikely for Volkswagen to be the only company that cheated on the emission tests, but we have to wait for the official results to see if they were right or wrong.
