Li Auto said the cause of the accident and detailed analysis of the results will be conducted at the scene of the accident.
The video and data show that at 16:08:54 on August 6, an object with a length of about 20 centimeters, suspected to be a piece of iron, appeared in front of the vehicle and then entered the bottom of the vehicle, which was traveling at 115 kilometers per hour.

Description of the incident
At approximately 16:09 on 6 August 2020, an accident occurred on the Erguang Expressway in Zhaoqing City, Guangdong Province, in the direction of Sihui and Lianzhou, resulting in a fire in a Li ONE.
Li Auto staff arrived at the scene immediately to confirm the condition of the user. Two passengers are currently in hospital for observation, while the rest of the occupants are safe.
According to video and data from the time of the accident, at 16:08:54 an object approximately 20cm in length, which appears to be a piece of iron, is seen in front of the vehicle. It then entered the underside of the vehicle, which was travelling at 115 km/h.
At 16:08:59, the fuel line pressure dropped abnormally. At 16:09:06, the driver pulled over and the vehicle caught fire.
According to the cloud-based monitoring data, there was no abnormality in the battery or range extender after the accident.
The cause of the accident was tentatively determined to be an object suspected of being an iron sheet that was rolled up by a high-speed vehicle and punctured the high-pressure fuel line, causing fuel to sputter and be ignited by the high temperature of the exhaust pipe.
The specific cause of the accident and detailed analysis of the results will be subject to the detailed investigation and analysis of the accident site.
