Core Viewpoint - The article discusses the proposed revisions to mandatory national standards for passenger vehicle fuel consumption and electric vehicle energy consumption, emphasizing the need for stricter regulations to enhance energy efficiency and support carbon reduction goals [4][5][16]. Summary by Sections Introduction of New Standards - The Ministry of Industry and Information Technology is soliciting opinions on four mandatory national standards, particularly focusing on the "Evaluation Methods and Indicators for Fuel Consumption of Passenger Cars" and "Energy Consumption Limits for Electric Vehicles" [4][5]. Changes in Fuel Consumption Evaluation Methods - The new standard replaces GB 27999-2019 and introduces a transition period of over six months, with implementation starting from January 1, 2026. It applies to M1 class vehicles, including various fuel types [5][7]. - Key changes include the definition of average fuel consumption for traditional energy passenger vehicles and average CO2 emissions for enterprises [7]. Determination of Fuel Consumption - The method for determining vehicle fuel consumption has been revised, with specific guidelines for different types of hybrid and electric vehicles, utilizing the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) [8][9]. Fuel Consumption Targets and CO2 Emissions - The new standard sets a comprehensive target for passenger vehicle fuel consumption by 2030, with specific calculations for vehicles with different seating capacities. It also introduces a method for calculating average CO2 emissions for enterprises [10][11]. Annual Requirements for Average Fuel Consumption - From 2026, the ratio of average fuel consumption to target values will be strictly regulated, with decreasing percentages each year until reaching 100% in 2030 [11][13]. Calculation of Average Fuel Consumption for Traditional Energy Vehicles - The new standard includes a detailed calculation method for average fuel consumption of traditional energy vehicles, emphasizing stricter compliance with energy-saving policies [14][15]. Importance of Standard Revision - The revision is crucial for national energy security, supporting carbon peak goals by promoting advanced low-carbon technologies, and facilitating the automotive industry's transformation towards high-quality development [16]. Electric Vehicle Energy Consumption Limits - The new standard for electric vehicles replaces GB/T 36980-2018 and introduces significant changes, including the application and determination of type approval for energy consumption limits [17][18]. - It also establishes production consistency requirements and criteria for determining the same vehicle type [20][21]. Significance of Electric Vehicle Standards - The revised standards aim to promote energy efficiency and low-carbon development in electric vehicles, enhance technological advancements in the automotive industry, and curb the trend of vehicle size increase [22].
