From August 21 to October 20, 2024, the Ministry of Industry and Information Technology (MIIT) is seeking public feedback on the revised mandatory national standard draft GB 27999 Fuel Consumption Evaluation Methods and Targets for Passenger Cars.

In March 2024, the State Council issued the Action Plan for Promoting Large-Scale Equipment Renewal and Consumer Goods Replacement. This document emphasized the need to "accelerate the improvement of energy consumption, emission, and technical standards, and to speed up the upgrade of energy consumption limits for passenger cars and heavy commercial vehicles." This indicates a clear need to enhance automotive energy-saving indicators and market entry thresholds. Consequently, in June 2024, China began revising the mandatory national standard GB 27999-2019 Fuel Consumption Evaluation Methods and Targets for Passenger Cars.

The main technical changes in this revision include: first, tightening the fuel consumption target values for passenger car models in line with national management requirements, expected technological advancements, and the impact of testing conditions; second, modifying the method for calculating the average fuel consumption of passenger car enterprises, including adjustments to the accounting multiple for new energy vehicles and the conversion method for energy consumption; and third, clarifying the annual fuel consumption target requirements for enterprises.

GB 27999 is one of the two main standards in China's passenger car fuel consumption regulation system (the other being GB 19578 Fuel Consumption Limits for Passenger Cars). The stricter fuel consumption indicators introduced by this revision will present new challenges for passenger car manufacturers. Given that the current standard GB 27999-2019 is for the period from 2021 to 2025, it is anticipated that the new standard will be quickly completed and released, coming into effect on January 1, 2026. It is advised that relevant enterprises prepare for these changes promptly.
