Ultra在高速行驶中发生碰撞后起火燃烧，现场多名人员参与救援但未能打开车门，驾驶员邓某某遇难。2026年2月，四川西华交通司法鉴定中心出具《司法鉴定意见书》，披露了该起燃爆事故的细节。第一财经记者从这一《司法鉴定意见书》获得的一些关键细节显示：涉事小米SU7 Ultra与前车碰撞时车速达167公里/小时，远超事发路段80公里/小时的限速。碰撞后低压系统断电，导致车门外把手电释放功能失效，这是现场救援人员无法打开车门的直接原因。驾驶员邓某某的死因系车辆起火燃烧，而非碰撞本身。EDR（事故数据记录器）记录显示，燃爆前6.5秒内，驾驶员曾三次启动制动系统。此外，事故中驾驶员安全带处于扣系状态，安全带预紧装置与座舱内7个标配安全气囊均未展开。从法律层面看，《道路交通事故认定书》已认定处于酒驾的驾驶员邓某某需要为这一事故负全责，但媒体曝光的四川亚峰律师事务所律师吴昊的声明认为，这份责任认定区分的是驾驶主次责任，与邓某某的死亡结果无必然因果关系。这一声明试图将公众的注意力从驾驶员的违规操作，转向车辆本身的安全设计。根据《司法鉴定意见书》，涉事车辆约在2025年10月13日03:18:51时撞上分隔带，3:19:00时低压系统断电, 导致车辆前后灯具及其他低压用电系统（包括门锁系统）不工作，车门外把手电释放功能失效。也就是说，碰撞后仅9秒，车辆低压系统便断电，导致电释放门把手失效，而该车型未配备外置机械把手，外部救援人员无法操作内部应急机械拉手，这段时间成为影响现场救援的关键因素。此外，涉事车辆右侧中后部及车顶部见过火痕迹，座舱内烧损程度严重，可燃物烧损、碳化，部分烧毁。客观而言，驾驶员严重超速是该事故发生的直接且首要原因。但小米汽车在这一事故中展现出的车门无法打开等实际安全表现，也让其再次陷入安全争议。回溯小米汽车的发展历程，安全始终是其对外宣传的关键词。自2024年3月首款车型SU7正式发布以来，小米汽车用不足20个月的时间，实现了50万辆下线的最快纪录，刷新了全球新能源车企的规模化速度。雷军在50万辆下线仪式上明确表示，“下一步，小米汽车将坚持不懈抓安全、抓交付，在保证安全和品质的基础上全力以赴加快生产”，并多次在公开场合重申“安全是基础，安全是前提”“安全高于一切”的核心理念。为支撑这一理念，小米对外详细披露了其四维安全体系：被动安全上，采用MI铠甲笼式钢铝混合车身，高强度钢与铝合金占比超90%，强度最高达2200MPa，还配备“丢轮保车”等主动防护技术；电池安全上，构建五重防护体系，通过超1000项安全实验，远超国标要求；主动安全上，全系标配激光雷达与高算力芯片，可提前2.5秒识别风险并启动分级制动。小米甚至在答网友问中承诺，SU7高速碰撞后，会自动降低车窗、点爆安全气囊、激活双闪、切断高压系统并呼叫救援，全维度保护乘员安全。结合公开信息来看，小米车主因超速引发交通事故已多次出现，但部分情况与上述宣传存在落差。除成都这起致死事故外，2025年3月，安徽铜陵也曾发生一起小米SU7高速碰撞事故，该事故中同样出现车门锁死情况，最终导致三人遇难。根据行业常规表述，安全气囊的展开受碰撞角度、力度、受力面积等多重因素影响，我国法律未对气囊弹出设定统一的硬性标准，因此小米SU7 Ultra此次气囊未展开，不能直接判定为产品缺陷。但车辆门把手设计存在的不足，确实成为阻碍救援、加剧事故后果的关键因素——在新能源汽车智能化、电子化的发展趋势下，小米为兼顾科技感与美观，采用纯电释放外把手，未配备外置机械把手，未充分考虑碰撞断电等极端场景下的逃生需求，这与“安全高于一切”的理念存在执行层面的偏差。值得注意的是，小米汽车在2026年2月上市的新款SU7中，新增机械应急开启结构，提前适配2027年车门把手新国标。这一改进是对市场争议的回应，也是对产品安全设计的完善，但其推出时间在成都事故发生之后。2026年2月，由工业和信息化部组织制定，市场监管总局、国家标准委批准发布的强制性国家标准《汽车车门把手安全技术要求》正式获批发布，将于2027年1月1日起正式实施。新国标对汽车门把手在机械冗余、操作空间、明确标识和结构强度上作出了明确要求。其中，要求车门内、外把手必须配备机械释放功能，确保在车辆断电等极端情况下能手动开门；车门外把手必须预留不小于特定尺寸的手部操作空间，确保易于抓握。对小米汽车的安全争议，背后也反映出跨界造车过程中“消费电子逻辑”与“汽车安全逻辑”的适配问题。小米从消费电子领域跨界而来，擅长以参数堆料、快速迭代、规模化扩张的模式抢占市场，这种模式使其在短时间内实现销量突破，但在这一过程中，对汽车行业核心的安全底线考量还需真正落到实处。对于汽车来说，颜值与参数不能替代安全，从SU7上市之初因中控物理按钮会“硌疼膝盖”，到极端场景下的安全冗余，其在造车的安全细节方面仍需提升。从行业层面来看，小米面临的问题，也是当前新兴车企中的共性问题。在电动化、智能化的市场竞争中，一些车企在追求科技感与差异化的过程中，将隐藏式门把手、无实体按键等设计作为产品卖点，却对其在极端场景下可能存在的安全风险考量不足；部分车企过度宣传安全配置与技术参数，但在实际落地过程中存在执行偏差。对于雷军而言，“抓安全、抓交付”的表态，需要更多实际行动来支撑。千亿研发投入、严苛的安全标准宣传，最终都要转化为产品的安全性能，才能真正赢得消费者的信任。","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"-1","news_tag":"policyRegulatory","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
