- Vehicles include continuous emission sensors, fault detection, connectivity to authorities, and tamper protection.
The Euro pollution standards have been in force since 1991, imposing increasingly stringent limits on vehicles traveling European roads. The new Euro 7 standard, officially presented by the European Commission on November 10, 2022, will replace Euro 6 (in force since 2014) and Euro VI for heavy vehicles.
According to specialists, Euro 7 will serve as a “defining set of pollutant characteristics for the latest generation of internal combustion engines in Europe”, marking the transition to zero-emission vehicles by 2035.
What the Euro 7 standard represents and its main changes
Unification of emission standards
For the first time, the Euro 7 rules bring together in a single regulatory bundle the emission limits for all motor vehicles:
- Passenger cars and light commercial vehicles (formerly Euro 6)
- Trucks and buses (formerly Euro VI)
- Electric and hybrid vehicles
Drastic reductions in pollutant emissions
The new regulations aim to significantly reduce emissions:
- NOx (nitrogen oxides): a 35% reduction for passenger cars and LCVs, 56% for trucks
- Fine particulates (PM): a 13% reduction for passenger cars and LCVs, 39% for trucks and buses
- Carbon monoxide (CO): improved control
- Hydrocarbons (HC): strict monitoring
- Nitrous oxide: special norms for heavy-duty vehicles
Technological and fuel neutrality
The Euro 7 standard imposes the same limits regardless of:
- Fuel type (gasoline, diesel, alternative fuels)
- Propulsion technology (internal combustion, electric, hybrid)
- Make and model of the vehicle
Revolutionary real-world testing
On-road tests in extreme conditions
Euro 7 introduces emissions tests that better reflect real-world use:
- Extreme temperatures: tests up to 45°C and at subzero temperatures
- Short urban trips: typical of daily commuter cycles
- Varied conditions: heavy traffic, hills, motorways
- Different altitudes: tests at sea level and in mountainous regions
Continuous sensor monitoring
All vehicles will be factory-equipped with:
- Monitoring sensors: continuous measurement of emissions
- Diagnostic systems: automatic fault detection
- Connectivity: data transmission to authorities
- Tamper prevention: protection against unauthorized modifications
