The weight of new energy vehicles (NEVs) has generally surged to 2 to 3 tons—with certain models nearing 4 tons—due to the incorporation of components like batteries. This increase has ignited a debate concerning road wear and tear and the potential implementation of road maintenance fees. Relevant authorities are actively exploring policy adjustments, such as the allocation of road maintenance fees and the overhaul of the automotive industry's tax and fee framework, to better align with the evolving industrial landscape. At present, many of the tax and fee standards governing the automotive sector remain rooted in policies from the previous century, which are no longer adequate to address the current demands of development. Therefore, comprehensive research should precede the introduction of tax and fee reforms in the automotive industry. Notably, numerous tax and fee exemptions and reductions previously enjoyed by NEVs are being gradually phased out. As the market continues to mature, further adjustments to relevant tax and fee policies may be warranted.

In response to the escalating vehicle weights, the national standard "Energy Consumption Limits for Electric Vehicles Part 1: Passenger Cars" was put into effect on January 1st of this year. By implementing stringent system indicator designs, it encourages technological advancements among automakers, enforces energy consumption limits, and curbs the trend of increasing vehicle weights in the electric vehicle sector. The purchase tax technical standards slated for implementation in 2026 stipulate that for pure electric vehicle models with a curb weight exceeding 2,710 kilograms to be eligible for a 50% reduction in purchase tax, their CLTC energy consumption per 100 kilometers must not surpass 19.1 kilowatt-hours. This measure, to a certain extent, discourages automakers from indiscriminately increasing vehicle weights.
