Euro 6 is the name of the current exhaust emission standard for pollutants. It defines lower maximum values for particulate matter and nitrogen oxide emissions than EU5. From September 2018*, the EU6c emission standard will become compulsory, and in comparison to EU6b it specifies even lower limits for the content of particulate matternumber in petrol-engine vehicles. The same threshold limit values apply for diesel-engine vehicles within the cycle for both EU6b and EU6c. EU6d-TEMP from September 2019* and EU6d from January 2021* will again slightly lower the threshold limit values for the number of particles and nitrogen oxides in line with RDE.
*Applies to new vehicles. New vehicle @types will each be subject to the new exhaust emission standards 1 year earlier.
