1.4 TSI in Tiguan and 2.0 TFSI in A5 will lead the way.

VW CEO Matthias Müller presented the “TOGETHER - Strategy 2025” plan in the second half of June and at that point he called it the “biggest change process in Volkswagen’s history.” During his speech, he talked about the company’s intentions of making gasoline engines cleaner by installing particulate filters. Now, VW is reiterating its plans for a wide-scale introduction of GPFs from next year on TSI and TFSI engines.

It is going to be standard equipment and will slash fine soot particles by as much as 90 percent, according to VW’s research. The rollout is scheduled to commence in June 2017 with the 1.4-liter TSI powering the Tiguan and the 2.0 TFSI available in the recently introduced Audi A5. GPFs will then be fitted to other engines and models from the VW Group and by 2022 annual sales of cars powered by engines with GPFs are estimated to reach seven million units.

On the diesel side, which is by far the most problematic at this point, VW wants to make its TDIs less harmful to the environment by fitting all turbodiesel-powered models across the group with the latest selective catalytic reduction (SCR) technology.

Interestingly, VW points out independent testing bodies have shown the company’s Euro 6-compliant gasoline and diesel engines are the cleanest in the business. London-based Emission Analytics’ EQUA Air Quality Index covered 440 of the most popular models and ranked VAG as “the top performer by some margin.” The group finished first in the Euro 6 gasoline engine category, as well as in Euro 5 gasoline and Euro 6 hybrid rankings. On top of that, the best six diesel cars with Euro 6 engines are from VW, Audi, and Skoda. In the top 10 of Euro 5-compliant diesel cars, there are five cars from the group and the top two come from Audi and Skoda.

Besides its push to make combustion engines cleaner, the VW Group is also working on a slew of alternatively-powered models, with the aforementioned “TOGETHER - Strategy 2025” revealing plans for 30 pure EVs by the middle of the next decade.

Volkswagen Group introduces particulate filter for petrol engines

  • Emissions of soot particles from direct injection petrol engines can be reduced by up to 90 per cent
  • Planned roll-out in Group models as of 2017

The Volkswagen Group is continuing to work assiduously on the environmental compatibility of conventional drive systems. The company has now decided upon wide-scale use of particulate filters for petrol engines, so-called 'gasoline particulate filters (GPF)'. From 2017, all Group direct injection TSI and TFSI engines will be fitted step-by-step with petrol particulate filters. Emissions of fine soot particles will be reduced in this way 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 Tiguan1 and the 2.0 TFSI in the Audi A52. Implementation will then follow in further models and engine generations.

Particulate filters for diesel engines are already proven and established. The gasoline particulate filter will now reduce the particulate emissions of direct injection petrol engines by up to 90 per cent. Dr. Ulrich Eichhorn, Head of Group Research and Development: "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."

Despite the outlay for complex exhaust gas treatment systems for new models, Volkswagen is determined to reduce its diesel vehicles' pollutant emissions as well. Eichhorn: "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology."

Using comparative measurements, independent testing bodies have established that both modern EU 6 diesel engines and petrol engines from the Volkswagen 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 Volkswagen Group as the top performer by some margin.

The company ranked first in three categories: EU 6 petrol engine, EU 5 petrol engine and EU 6 hybrid vehicles. The best six EU 6 diesel vehicles also come from Volkswagen, Audi and Skoda; among the EU 5 diesels tested, a total of five models in the top 10, including the top two from Audi and Skoda, are also from the Volkswagen Group.
