Euro 7 has become central to the recent automotive news agenda. One of the most debated issues was the confusion between the effective date and the date the new regulation would be implemented. Therefore, although many people thought Euro 7 would come into effect this year, this is not the case. The regulation was published in the European Union on May 8, 2024, and came into force on May 28, 2024. These implementation dates directly affected manufacturer processes and sales schedules.
The actual transition plan for passenger cars and light commercial vehicles is set for November 29, 2026. This applies to vehicles that will receive new type approval. For models currently on sale with existing type approval, the transition will take place on November 29, 2027, and from that date onwards, all new M1 and N1 class vehicles sold on the European market will have to comply with Euro 7 requirements. The date for heavy commercial vehicles is further in the future: May 29, 2028 for new type approval, and May 29, 2029 as the final date for all new vehicles to comply with Euro 7. This process indicates that the regulation did not begin in a single day; the transition is first implemented for new designs, followed by the sales side of existing models.
The situation of current vehicle owners is also important at this point. Euro 7 focuses on new type approvals and new vehicle sales, rather than suddenly retiring existing vehicles from the road. Euro 6 vehicles currently in use will not suddenly become obsolete due to the regulation; the change will be felt in manufacturers' processes for developing and selling new vehicles.
Euro 7 goes beyond just exhaust emissions, expanding the scope of the regulations and limits. The new regulation also covers particulate matter from brakes, tire wear, battery life, and emission system lifespan. This brings hybrid and electric vehicles under its purview. While most of the basic emission limits from the Euro 6 era are retained for passenger and light commercial vehicles, new measurement methods are being introduced in some areas.
Particulate emissions from braking systems are directly limited, and these rules apply to internal combustion engines, hybrids, and electric vehicles. Battery endurance in electric vehicles is also clearly defined; there is a requirement to maintain a minimum capacity within specific mileage and annual values. Separate limits are stipulated for the first five years or 100 kilometers, and for periods after 8 years or 160 kilometers.
This regulation, which also impacts the future used electric vehicle market, mandates systems designed to monitor battery health. Furthermore, an environmental vehicle passport is being introduced for each vehicle, recording environmental data, consumption figures, and battery durability at the time of registration. Monitoring emission performance throughout the vehicle's lifespan requires manufacturers to go beyond just laboratory testing. On-the-road performance is also monitored through sensors and software.
Stricter limits will be applied to heavy commercial vehicles; long-haul transport, especially for diesel engines, will require extensive adaptations in terms of engine, exhaust treatment, and software. Limits are being raised for particulate emissions from braking, including tire wear. The transition is earlier for C1 class tires, while later dates are being considered for C2 and C3 classes. For electric vehicles, battery monitoring and durability requirements are being clarified, and emission performance will be monitored throughout the vehicle's lifespan. This approach, which goes beyond gasoline and diesel vehicles, focuses on common goals across all powertrain types.
These new standards also bring about a major change in terms of environmental records and data transparency. With the environmental vehicle passport, consumption, emissions, and battery performance of vehicles will be recorded from the time of registration and can be monitored over the years. However, in addition to the individual effects of the regulation, battery and tire manufacturers are also directly involved in the process for the automotive ecosystem. This transformation brings not only stricter emission limits but also long-term monitoring of vehicles based on reliability and durability.
