You’ve heard of diesel particulate filters, but petrol ones? The Volkswagen Group has decided upon wide-scale use of particulate filters for petrol engines. From 2017, all VW Group direct injection TSI and TFSI engines will be fitted step-by-step with these gasoline particulate filters (GPF). Emissions of fine soot particles will be reduced by up to 90% as a result.

By 2022, the number of VW Group vehicles being equipped with this technology annually could reach seven million, Wolfsburg says. 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 new Audi A5. Implementation will then follow in further models and engine generations.

“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,” said Dr Ulrich Eichhorn, head of group research and development.

VW is also determined to reduce its diesel vehicles’ pollutant emissions as well. “In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology,” Eichhorn added.

VW says that using comparative measurements, independent testing bodies have established that both modern EU6 diesel and petrol engines from the Group are already the cleanest on the market. In its EQUA Air Quality Index, for example, London-based Emission Analytics looked at the world’s 440 most popular models and ranked the German group as the top performer by some margin.

The company that has been caught in the “Dieselgate” emissions scandal ranked first in three categories: EU6 petrol engine, EU5 petrol engine and EU6 hybrid vehicles. The best six EU6 diesel vehicles also come from Volkswagen, Audi and Skoda; among the EU5 diesels tested, a total of five models in the top 10, including the top two from Audi and Skoda, are also from the VW Group.
