The Euro 5 and Euro 6 emission standards play a crucial role in the environmental compatibility of vehicles. But what exactly differentiates these two standards, and what impact do they have on drivers and car mechanics? This article clarifies the most important questions regarding the difference between Euro 5 and Euro 6.
What Do Euro 5 and Euro 6 Mean?
Euro 5 and Euro 6 are European emission standards that set limits for pollutant emissions from vehicles. They aim to improve air quality and reduce environmental impact. These standards were introduced in stages, with Euro 5 introduced for new vehicle types in 2009 and Euro 6 in 2014.
The Main Differences Between Euro 5 and Euro 6
The main difference between Euro 5 and Euro 6 lies in the stricter limits for nitrogen oxides (NOx) and particulate matter. While Euro 5 stipulates a limit of 180 mg/km for NOx in diesel vehicles, Euro 6 reduces this value to 80 mg/km. The limits for particulate matter, particularly the number of particles, have also been significantly tightened. “Reducing NOx emissions is crucial for people’s health,” emphasizes Dr. Hans Müller, an expert in exhaust technology, in his book “Modern Exhaust Gas Purification Systems.”
For car mechanics, the introduction of Euro 6 means new challenges. The more complex exhaust aftertreatment systems require special knowledge and tools for diagnosis and repair. “Further training in the field of exhaust technology is essential for car mechanics,” says the renowned automotive expert, Eng. Klaus Schmidt.
Impact on Drivers
For drivers, Euro 6 generally means higher purchase costs for vehicles. The more complex exhaust purification technology is reflected in the purchase price. In addition, higher maintenance costs can arise due to the more elaborate systems. “However, investing in a Euro 6 vehicle is a contribution to environmental protection and health,” says Dr. Müller.

Advantages of Euro 6 for the Environment
The stricter emission standards of Euro 6 significantly contribute to improving air quality. The reduced pollutant emissions minimize health risks for the population and protect the environment.
Questions and Answers About Euro 5 and Euro 6
- What is AdBlue? AdBlue is a urea solution used in diesel vehicles with SCR catalysts to reduce NOx emissions.
- How often does the DPF need to be regenerated? The diesel particulate filter regenerates automatically during driving.
- Which vehicles must comply with the Euro 6 standard? All newly registered vehicles must comply with the respective Euro standard.
