Euro 7: What's really changing?

The Euro 7 regulation marks a significant step forward in the evolution of environmental standards for vehicles, but not as drastic as many imagine. For cars and vans, the most significant change isn't a radical reduction in existing emissions limits, but rather a broadening of the scope: emissions from brakes and tires are now also taken into account, there's increased focus on performance durability over time, and specific requirements for the batteries of electric and plug-in hybrid vehicles are introduced.

It's not just a new version of Euro 6

The key point is this: Euro 7 doesn't simply "tighten" existing parameters. For cars and vans, exhaust emission limits remain largely aligned with those of Euro 6, while the real regulatory leap concerns what were previously less addressed or completely excluded: brake particulate matter, tire abrasion, battery life, and the durability of the vehicle's environmental performance over time.

For cars and vans, exhaust emissions limits do not change radically

For passenger cars and light commercial vehicles, the test conditions and exhaust limits remain substantially those of Euro 6, even if more stringent requirements for some solid particles and, above all, a broader control framework are introduced. This is why many headlines speak of a "revolution", but the technical reality is more nuanced: the paradigm shift is above all in the type of controlled emissions and in the duration of compliance with the rule.

The real novelties of Euro 7

1. Brake emissions come into play

For the first time, European standards include limits on particulate matter emitted during braking. This is a significant development because it shifts attention to a source of pollution that remains critical even with the spread of electric vehicles. In other words, we're no longer just looking at the exhaust pipe.

2. The issue of tire abrasion arrives

Euro 7 also takes into account emissions related to tire wear, including microparticles and abrasion. This is a significant regulatory breakthrough because it affects all fuel systems, including electric cars, which have no exhaust emissions but still generate non-exhaust emissions.

3. Batteries become part of environmental compliance

For the first time, the standard introduces minimum durability requirements for batteries in electric and plug-in hybrid cars. For cars, the battery must maintain at least80% of the capacity up to 5 years or 100,000 km and at least the 72% until 8 years or 160,000 km. For vans, the thresholds drop to respectively 75% e 67%.

4. Vehicles must remain compliant longer

The logic of the regulation also changes in terms of durability: the vehicle must remain compliant for a longer lifespan, not just in the initial years. The Commission, already in its proposal, spoke of a doubling of the durability requirements compared to the previous framework; many analyses summarize this change as an extension up to 10 years or 200,000 km for cars.

5. More data available with the vehicle environmental passport

The regulation also provides for a Environmental Vehicle Passport, a digital card with information on the vehicle's environmental performance at the time of registration, including emissions limits, fuel consumption, electric range, and battery life. This feature enhances transparency and technical traceability.

Since it comes into force

After the final adoption by the EU Council in April 2024, the application will be staggered by vehicle type. new types of cars and vans, the regulation applies after 30 months; for all the new cars and new vans After 42 months. Translated into practical terms, the most up-to-date editorial reconstructions place the launch of the new models at end of November 2026, with extension to new vehicles sold to end of 2027.

For buses, trucks and trailers, the departure is further ahead: 48 months for new types and 60 months for new vehicles.

What changes for those who buy a car

For the consumer, the change is not so much “from tomorrow all cars will be different”, but rather this:

• new approvals will have to comply with broader environmental controls;

• manufacturers will have to work more on brakes, particulate management, monitoring and battery;

• Future cars could become more technically complex and, in some cases, more expensive to produce.

What doesn't change for those who already have a car

Euro 7 does not impose to replace a vehicle already registered and does not automatically transform A compliant car today will be a "substandard" vehicle tomorrow. The regulation concerns the approval and marketing of new vehicles, not a general retroactive effect on the existing fleet.

Why this rule also applies to electric cars

One of the most interesting aspects is that Euro 7 goes beyond the idea that only internal combustion engines are environmentally relevant. Electric vehicles also fall within the regulatory framework through:

• brake particulate matter;

• tire abrasion;

• battery life requirements.
  This broadens the concept of “environmental performance” from just exhaust emissions to the entire behavior of the vehicle in use.

The most important aspect to understand

The real difference introduced by Euro 7 is that the vehicle is assessed more comprehensively and less "exhaust-centric." This means a more modern regulation, better suited to a market transitioning between internal combustion, hybrid, and electric vehicles, and more consistent with the fact that a car's environmental impact depends on more than just its engine.

FAQ

Does Euro 7 lower exhaust emissions for all cars?

Not so drastically for cars and vans: for these vehicles, the exhaust limits remain largely aligned with Euro 6. The most significant changes concern emissions from brakes, tyres, batteries and durability.

Does Euro 7 also apply to electric cars?

Yes. Not for exhaust gases, but for brake and tire emissions and for battery life requirements.

When does Euro 7 start?

For new types of cars and vans, application is expected 30 months after the regulation comes into force, which in practical summaries corresponds to the end of 2026; for all new cars and vans, approximately 42 months, i.e. the end of 2027.

Does Euro 7 require you to change your car?

No. The law regulates new vehicles and new approvals; it does not automatically require the replacement of cars already in circulation.

The advice of CDR Italia: If the radiator is more than 10 years old or over 200,000 km, the regeneration often it is not enough. In these cases, the replacement With a high-quality component is the only way to protect the value of your vehicle.
