Chengdu Accident Investigation Results for Xiaomi SU7 Ultra Released

[Safety Incident] Investigation results disclosed regarding the fatal Chengdu crash involving a Xiaomi SU7 Ultra caused by drunk driving and excessive speed.

Core Findings: 167 km/h Overspeed Impact and Low-Voltage Power Loss Leading to Door Failure

Three seconds before impact, the vehicle was traveling over 200 km/h, far exceeding the road’s speed limit of 80 km/h. The violent collision caused high-voltage electricity to surge into the low-voltage system, resulting in a complete power failure that disabled external electronically controlled doors.

Key Facts: Drunk Driving + Full Liability + Death by Fire

The driver, Deng Moumou (31 years old), was found to have been driving under the influence and severely overspeeding, bearing full responsibility for the accident. Forensic examination determined the cause of death was vehicle fire and combustion, not direct trauma from the collision.

Strategic Insight: Electronically Controlled Doors Pose Risks in Extreme Scenarios

The involved model, SU7 Ultra, lacks external mechanical door handles. After low-voltage power loss, doors cannot be unlocked from outside. The interior hidden mechanical release is extremely difficult to operate during rollover and fire conditions, revealing insufficient safety redundancy.
