China: New GB standards for energy consumption of cars

 

China has published two new standards relating to the energy consumption of cars – one for fuel, and one for electric cars.  These standards are:

GB 27999—XXXX Fuel consumption evaluation methods and targets for passenger cars

GB 36980.1—XXXX Energy consumption limits for electric vehicles—Part 1: Passenger cars

The first one specifies the evaluation methods and indicators, conformity of production, same type judgment, and implementation date for fuel consumption of passenger cars and corporate average fuel consumption. The main contents of this revision include: changing the scope; adjusting the method of fuel consumption for vehicle models; adjusting the fuel consumption target; adding the calculation method for the reference value of the average CO2 emissions of corporate, and removing the multiple of vehicle model accounting for corporate average fuel consumption; adjusting the targets of corporate average fuel consumption; adding the calculation method for the corporate average fuel consumption of traditional energy passenger cars. 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.

For the second one, the implementation date is also January 1, 2026. For products newly applied for type approval, it will be implemented from the implementation date of this document. For products that have obtained the type approval, the implementation will start from the 25th month from the implementation date of this document.
