The standard applies to M1 vehicles, including vehicles capable of burning gasoline or diesel fuel, battery electric vehicles, fuel cell vehicles, and vehicles burning gas and alcohol-ether fuels.

The second one specifies the limits for energy consumption, application and determination of type approval, conformity of production, same type judgment for battery electric passenger cars. The main contents of this revision include: adding application and determination of type approval, changing the energy consumption limits, adding conformity of production, adding criteria for same type judgment, adding energy consumption type approval report and type approval application report.  It applies to M1 category battery electric vehicles with a maximum design total mass not exceeding 3500 kg.

The proposed date of entry into force of the first one is the 1 January 2026.
