Euro 7 emissions standard: Is there a threat of the end of combustion engines from 2025?

Does the new Euro 7 emissions standard threaten the end of gasoline and diesel engines?

With the Euro 7 standard, the EU Commission is planning the strictest emission regulations for new cars. Is there a threat of the end of gasoline and diesel engines in 2025? A heated discussion has started!

R.and 3.6 million new cars were registered in Germany in 2019, due to the coronavirus there will be fewer in 2020. From 2025, if the new Euro 7 emissions standard is to come into force across the EU, there could be a lot less – because some cars can no longer exist. The EU Commission, led by Ursula von der Leyen, plans the strictest emission regulations to date with the next Euro standard.

In an initial reaction, the Association of the Automotive Industry (VDA) warned of serious effects on the future of gasoline and diesel vehicles. But there is also approval.

New vehicles should comply with these pollutant values ​​from 2025

EU Commission - RDE test graphic

The graphic shows: With Euro 7, the limit values ​​are significantly lower – without the exceptions permitted today.


The strict fleet targets for CO2 emissions have long been decided, now the issue is pollutants such as NOx, which have already led to driving bans in many European cities. A 66-page study by experts from all over Europe (“Advisory Group on Vehicle Emission Standards”), which is available to AUTO BILD, is being discussed on behalf of the EU. The content:

In future, new cars should only be allowed to emit NOx at 30 mg / km, in a second scenario even only 10 mg / km. Previous limit values: 60 mg for petrol, 80 mg for diesel. Carbon monoxide should be reduced from 1000 or 500 mg to 300 or 100 mg.
• The RDE testwho uses a mobile measuring device to measure compliance with the limit values ​​while driving (PEMS, Portable Emission Measurement System), should be tightened. RDE (Real Driving Emissions) takes certain parameters into account (average speed, outside temperature, sea level, at least 16 km of driving distance). Example: After a cold start, until the catalytic converter is warm, a car emits more pollutants than at operating temperature – also at full throttle. With the new test, full throttle is allowed, theoretically all the time, only is the route is much shorter at 5 km. In the future, cars will have to comply with these values ​​at temperatures of minus 10 to plus 40 degrees, even at an altitude of 1000 or 2000 meters (previously a maximum of 700 m) and over a theoretical “lifetime” of 15 years or 240,000 km of mileage (previously 160,000). The rules should also apply to roof boxes, bike racks or trailers.

The previous measurement tolerance of the PEMS of 25 to 30 mg is to be eliminated. Overall, this means that in order to get safely below 30 mg, a car should actually emit 0 mg NOx. That would be a challenge to modern combustion engines, which are just as clean as never before.

Industry association considers standards to be utopian

Hildegard Muller

VDA President Müller sharply criticized the planned EU regulations for exhaust emissions.


Industry experts talk about a “declaration of war” and the de facto end for diesel and gasoline enginesif Euro 7 were to be so decided. “The commission wants to stipulate that in the future a vehicle must remain virtually emission-free in every driving situation – be it with a trailer on a mountain or in slow city traffic. That is technically impossible, and everyone knows that,” criticized the head of the VDA industry association, Hildegard Müller . Engineers say the standards are set in such a way that they cannot be met at all.

Dudenhöffer: “VDA shouting incomprehensible”

Prof. Ferdinand Dudenhöffer, however, criticized the industry association: “The screaming of the VDA is incomprehensible. How to achieve important nitrogen oxide emissions many diesel vehicle models already have the values ​​planned for 2025 today. And: In China, gasoline engine limit values ​​will already apply from 2021, which are half as high as in the EU today, “said the director of the CAR Institute in Duisburg to AUTO BILD. Dudenhöffer believes that the additional costs through stricter emissions standards will be manageable. “I guess we’re talking there a maximum of 1000 euros per car“Even with the diesel particulate filter, the auto industry once warned of immense additional costs in” bad news “.” And today a part like this for the car manufacturer’s new car production costs maybe 200 euros. ” Dudenhöffer considers new limit values ​​to be overdue: “The current emission regulations are from 2014. So it is only understandable that after ten years the new Euro 7 standard will come.”
