After the Dieselgate scandal, Volkswagen is making the best of its particulate filters in order to not repeat the mistake. The German manufacturer announced that these particulate filters will also be introduced on the petrol engines.

The gasoline particulate filter will now reduce the particulate emissions of direct injection petrol engines by up to 90 per cent.

By 2022, the number of Volkswagen Group vehicles being equipped with this technology annually could reach seven million. The process is starting in June 2017 with the 1.4-litre TSI engine in the new Volkswagen Tiguan and the 2.0 TFSI in the Audi A5. Implementation will then follow in further models and engine generations.

Dr. Ulrich Eichhorn, Head of Group Research and Development said: "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard."
