Rainwater Technologies reported on June 28 that some media outlets tested the Xiaomi Yu7 on the track and saw fire on the brake pads, which drew a lot of attention.
Xiaomi Auto’s official Weibo account was quick to explain the issue. The statement noted that the Xiaomi Yu7 Max in the video was stopped directly under extreme conditions without a radiator cooling cycle, which caused the brake pads to burn due to short beads and flying rings from the Tianjin V1 race track. Xiaomi has officially emphasized that the braking system itself has no failure issues and all functions are working properly.
Specifically, it’s worth noting that the test kit at the time did not use the “Energy Recovery Enhancement” feature in Xiaomi’s YU7 Max Master mode. Xiaomi emphasizes that this feature is designed to increase the intensity of energy recovery in track conditions, thereby reducing the burden on the mechanical braking system. Even with ABS locking, this feature can still provide up to 0.2G of braking energy recovery, which effectively reduces extreme conditions at braking system temperatures of 600°C and above.
Official note from Xiaomi: In a railroad driving environment, vehicles are often required to brake at ultra-high speeds, making the braking system even more taxing than in daily driving. Under such extreme operating conditions, the temperature of the brake discs will rise rapidly, which can lead to material launch if effective heat dissipation measures are not taken. This is similar to any high-performance tool on the track, and it’s not an issue unique to Xiaomi.
Additionally, as a mid-size and large SUV, the Xiaomi Yu7 weighs more and has a relatively small, high-powered performance SUV, resulting in a higher track tail. All of these factors mean that the braking system generates more heat during forced braking. Effective cooling is therefore vital and basic common sense in track driving. Good braking performance is closely linked to cooling capacity and cannot be ignored in any vehicle when challenging track limits.
The Xiaomi Yu7 Max uses low-metal brake pads, which include metallic fibers, abrasives, resins, and other organics. Under high temperature environments (usually above 300°C), resins and other organic matter will undergo a rupture reaction of polymer branches, resulting in moisture, carbon monoxide, carbon monoxide and other organic matter. resulting in moisture, carbon monoxide, carbon dioxide Millet formally states that this is a normal bodily phenomenon that does not lead to braking performance failure.
The Xiaomi Yu7 is positioned as an urban luxury high-performance SUV. Xiaomi officials also strongly recommend that you should not try the track easily without professional upgrades and preparation. We must learn driving skills step by step to fully understand the boundaries of product performance and to master the boundaries of professional driving knowledge. Safe driving is always a top priority for the average consumer.
If you really want to drive professionally, you need to upgrade the vehicle’s tires, braking system, dissipation and dissipation of key components, and use the main mode and turn on the energy recovery enhancements to avoid safety risks in extreme operating conditions. This reflects Xiaomi’s strict approach to safety.
