此监管升级紧随多起高关注致死事故：在中国发生的两起Xiaomi Corp.电动车起火撞击事件中，外界怀疑因断电导致车门无法开启，使乘员无法逃生或被救援而死亡。虽然新规仅直接约束在中国销售的电动车，但中国在全球汽车供应链与市场规模上的权重，使其标准可能外溢；Tesla的车门设计已在美国面临安全调查，欧洲监管机构亦在研议制定相应规则。Bill Russo（Automobility创办人）将此解读为中国从「最大电动车市场」转向「新技术监管规则制定者」，并可能借由国内市场规模锁定可由本土与外资车厂共同遵循的安全标准，进而随中国电动车出口影响全球规范。
成本与冲击呈现不均：一位熟悉中国电动车厂设计流程的人士估算，每一款车型改造成本可能超过1亿元人民币（约1,440万美元）。设计普及度高，China Daily曾报导，在某年4月的「前100名畅销新能源车」中约60%配备隐藏式把手；因此改造可能优先集中在高毛利的豪华车型，包括Tesla Model Y与Model 3、BMW iX3（中国版计划于2026年推出）、以及Nio ES8、Li Auto i8、Xpeng P7等；Xiaomi的YU7（2025年6月上市）亦需调整，且其SU7在2025年3月与2025年10月各发生一起致命事故，加速了规范推进。技术细则要求车外需有至少6公分×2公分（原文亦标示2.4英吋×0.8英吋）的凹槽供手抓握把手，车内需有不小于1公分×0.7公分的开门标示并规定配置位置；新规也使部分既有备援（如机械拉索、备援门电池）在功能上可能变得冗余。部分车企已回归外露把手（如Geely Galaxy M9、BYD Seal 06），Tesla表示将为中国做必要调整，且Chair Robyn Denholm提到正考虑在电池电压偏低时让车锁自动解锁；同时，中国亦计划限制起步加速能力并加强对先进驾驶辅助系统的监管。
China’s Ministry of Industry and Information Technology issued new safety rules on 2026-02-02 21:17 (GMT+8 = UTC+8) banning concealed/flush door handles on electric vehicles, making China the first country to outlaw a design popularized by Tesla Inc. From 2027-01-01, cars sold in China must provide a mechanical release both inside and outside. Models already approved and nearing launch get a transition window until 2029-01 to change designs.
The crackdown follows multiple high-profile fatal incidents, including two fiery Xiaomi Corp. EV crashes in China where suspected power failures may have prevented doors from opening, leaving occupants unable to escape or be rescued. Although the rules apply to EVs sold in China, China’s scale in the auto industry makes spillover likely: Tesla’s doors face a safety probe in the US, and European regulators are considering their own requirements. Bill Russo, founder of Automobility, frames the move as China shifting from the largest EV market to a rule-setter that can lock in safety standards domestically and potentially export them through Chinese EV sales abroad.
Costs and impacts appear uneven: a person familiar with a Chinese EV maker’s design process estimated redesign could exceed 100 million yuan (about $14.4 million) per model. Adoption is widespread—about 60% of the top 100 selling new-energy vehicles in one April reportedly used concealed handles—so changes likely concentrate on higher-margin luxury models such as Tesla’s Model Y and Model 3, BMW’s iX3 (China version due in 2026), and models from Nio, Li Auto, and Xpeng; Xiaomi’s YU7 (launched June 2025) also needs an overhaul, after SU7 fatal crashes in March 2025 and October 2025 pushed the issue into public view. The rules specify an exterior recessed space at least 6 cm by 2 cm (also noted as 2.4 in by 0.8 in) for grasping a handle, plus interior signage no smaller than 1 cm by 0.7 cm with placement requirements; they may also render some existing backups (e.g., pull-cables and backup door batteries) redundant. Some makers have already reverted to exposed handles (e.g., Geely’s Galaxy M9 and BYD’s Seal 06); Tesla says it will make necessary China changes, and Chair Robyn Denholm has said Tesla is considering auto-unlocking when battery voltage is low, alongside broader Chinese moves to limit standstill acceleration and tighten oversight of advanced driver-assistance systems.
