In a remarkable display of safety engineering, a BYD Qin L plug-in hybrid sedan was involved in a severe accident, as captured in viral footage reported by TT. Despite significant front-end damage from a 45-degree collision with a gasoline-powered sedan, the electric vehicle’s safety mechanisms effectively prevented a battery fire, contrasting sharply with the gasoline vehicle, which burst into flames.
The Qin L’s lithium-iron phosphate blade battery pack remained intact, with no signs of thermal runaway. Upon collision, sensors activated an automatic high-voltage power cut-off. Fortunately, all passengers escaped unharmed before emergency services arrived.
Crash Site Insights
Based on the vehicle registration (辽B FA9218), the crash took place in Dalian, Liaoning Province. Local infrastructure, including a nearby Jinghua Car Wash and distinctive northern municipal features, helped pinpoint the location. The gasoline vehicle was identified as a third-generation Mazda 3 Axela from 2014 to 2019, confirmed by its door contours and window shapes despite severe fire damage.


Advanced Battery Safety Features
The BYD Qin L’s battery system employs quick-response high-voltage circuit isolation, preventing electrical arcing within milliseconds of impact. The lithium iron phosphate blade batteries are designed to resist oxygen release, maintaining stability even under physical stress. This ensures the battery pack remains inert, safeguarding the vehicle’s occupants.
Upon impact, the vehicle’s safety systems activated dual airbags and a transmission gear lock, immobilizing the vehicle to protect against fire hazards. The safety measures ensure that electrical pathways are severed, enhancing occupant safety.
Fire safety in vehicles is a critical concern in China’s automotive market. Real-world incidents, such as the poplar fluff fire and the spontaneous combustion of a sedan, underscore the importance of effective crash-triggered isolation protocols.
Market Performance
The BYD Qin L is positioned in a competitive market segment with pricing under 150,000 yuan (approximately 21,000 USD). According to data from the China EV DataTracker, the model saw domestic deliveries of 10,019 units in May 2026, reflecting a decrease from the peak of 31,304 units in June 2025.
