A dazzling flame cut through the night sky on Tianfu Avenue in Chengdu. An out-of-control new energy vehicle exploded instantly after the impact. The flames were like a ferocious beast, completely engulfing the car body within 90 seconds. The exclamations of passers-by, the futile knocking, the final harsh sound of cutting the car body - all these efforts failed to save the life inside the cab.
This tragedy that occurred in the early morning of October 13 was not only a traffic accident, but also a concentrated exposure of new energy vehicle safety issues. Three fatal details are shocking: the door cannot be opened inside or outside after the collision, the battery pack explodes rapidly under a seemingly low-speed impact, and conventional rescue tools completely fail.
Video from the scene showed enthusiastic passers-by elbowing and kicking the car window, but the glass was extremely strong. Xiaomi officials once claimed that the SU7 would automatically switch to mechanical unlocking after a collision, but a fatal situation occurred at the accident site where "the door could not be opened due to power outage."

This tragedy that occurred in the early morning of October 13 was not only a traffic accident, but also a concentrated exposure of new energy vehicle safety issues. Three fatal details are shocking: the door cannot be opened inside or outside after the collision, the battery pack explodes rapidly under a seemingly low-speed impact, and conventional rescue tools completely fail.
Hidden door handles: the life and death test behind aesthetics
Video from the scene showed enthusiastic passers-by elbowing and kicking the car window, but the glass was extremely strong. Xiaomi officials once claimed that the SU7 would automatically switch to mechanical unlocking after a collision, but a fatal situation occurred at the accident site where "the door could not be opened due to power outage."
Automobile safety engineers analyzed that the semi-hidden electronic door handle used by Xiaomi SU7 relies entirely on electronically controlled switches, while the traditional mechanical pull ring is placed lower on the inside of the door.
When a serious vehicle collision causes the entire vehicle to lose power, the external electronic door handle immediately fails, and the internal mechanical device needs to be smashed through the window and reached out to operate - this is an almost impossible task in the face of a rapidly spreading fire.
Comparing the 2024 data of China Insurance Research Institute, the probability of the door successfully popping open after a side collision for models equipped with electronic door handles is only 67%, which is far lower than the 98% of traditional mechanical door handles. Behind these cold numbers is a cruel choice between design aesthetics and life safety.
Battery deflagration: potential safety hazards of 800V high-voltage platforms
The flames spread upward from the chassis and engulfed the entire body in just 40 seconds. Industry experts analyze that the 800V high-voltage platform used by SU7 has extremely high requirements for battery separator materials. If the structural protection is insufficient, slight collisions may also trigger a thermal runaway chain reaction.
The police report showed that the vehicle in the accident collided and crossed the green belt, and its impact may have been far greater than expected. No matter what advanced battery technology is used, when lithium-ion batteries are severely physically squeezed, they may cause internal short circuits and lead to thermal runaway. In contrast, BYD's blade battery disperses impact force through a honeycomb structure, CATL's Kirin battery is equipped with an independent explosion-proof valve, and whether there is a compromise in Xiaomi's battery safety design has become an urgent question to be answered.
Failure of the rescue system: traditional methods are helpless in the face of new energy fires
Rescuers on the scene tried to use fire extinguishers to put out the fire, but were unable to stop the spread of the fire. Traditional fuel vehicle fires can be controlled with dry powder fire extinguishers, but lithium battery fires require continuous cooling to prevent re-ignition. What's even more serious is that the high-voltage system of electric vehicles forces firefighters to wait for professional power-off equipment, and existing rescue training has not yet popularized these new procedures.
This exposes the contradiction between the rapid development of new energy vehicles and the lagging emergency rescue system. When the speed of technology iteration far exceeds the development of standards and the update of rescue training, the occurrence of similar tragedies is almost inevitable.
The price of silence: Technological loopholes trigger crisis of trust
After the accident, Lei Jun and his team's "silent response" triggered an avalanche of public opinion. Weibo lost 290,000 followers, its market value evaporated by HK$120 billion, and old cases were brought up again—this tragedy has evolved from a technical failure into a crisis of trust.
At present, the domestic smart electric vehicle industry is falling into a development paradox of "emphasis on experience and neglect of safety". When car companies are crazily stacking screen size and computing power parameters, do they not regard "collision-power-off-escape" as the highest priority? In the face of the right to life, any technical brilliance pales in comparison.
Industry dilemmas and solutions
The "Technical Requirements for Automobile Door Handle Safety" being formulated by the Ministry of Industry and Information Technology for public comment has exposed the serious lack of "escapeability" assessment in current crash tests at the right time. The problem of standards lagging behind technological innovation has become a common challenge that the new energy automobile industry must face.
This tragedy is a warning to the entire industry: safety redundancy design is not a cost burden, but a life insurance. Whether the car door can be opened after a collision, whether the battery pack has multiple protections, and whether rescuers can rescue quickly - these basic safety issues should be given higher priority than cruising range and smart configuration.
New energy vehicles represent the future direction of travel, but the development of any technology should not be at the expense of safety. When a car becomes an inescapable "mobile stove" after an accident, we have to reflect on whether, while pursuing intelligence and beauty, we have forgotten the most fundamental mission of the car - to safely deliver passengers to their destinations.
The value of life cannot be measured by parameters, and security vulnerabilities will not disappear through silence. This tragedy should serve as an opportunity for the entire industry to self-examine and promote comprehensive upgrades from technical standards to rescue systems.
