Small Engine Fire Incident Involving Xiaomi Yu 7
Xiaomi officials have addressed the recent incident in which a Xiaomi Yu 7 car experienced an engine fire during a test drive on a circuit. According to official statements, frequent emergency braking at high speeds can lead to sudden and significant increases in brake disc temperature.
The company emphasized that this is a normal physical phenomenon, but it does not affect the overall performance of the braking system. Additionally, officials clarified that the vehicle's performance was normal throughout the incident, with no loss of braking functionality.
In response to reports, officials stated that:
- The test car was stopped directly following the second lap and failed to undergo any heat dissipation processes under extreme conditions, resulting in a fire caused by the organic materials in its brakes.
- The system however remained functional. The test vehicle did not use the 'Energy Recovery Boosting' mode, which would have enhanced energy recovery at circuit speeds. This function increases strength under extreme driving situations, even while ABS is locked and provides maximum 0.2G braking force.
During high-speed racing, the car requires frequent emergency braking, leading to increased temperature on its brake components as part of this normal process. High heat levels can occur if adequate heat dissipation procedures are not applied to the vehicle at extreme circuit speeds or conditions, resulting from inherent physical effects.
Racing involves intense demands that significantly increase the stress on brakes compared to driving in everyday conditions. Braking and cooling requirements in motorsport differ substantially from those applicable during regular travel. Consequently drivers must realize the importance of implementing proper and thorough heat dissipation techniques in order to meet this demand effectively.
