If I frequently drive on race tracks, which parts of the vehicle require special attention for maintenance?

Official answer
Compared to daily driving, intense track driving places higher demands on the vehicle's condition. Overall, the Xiaomi SU7 Ultra has undergone thorough validation and tuning on the Nürburgring Nordschleife in Germany and several top-tier racing circuits in China, ensuring it meets reliability requirements even under prolonged track conditions. However, we still recommend visiting an official Xiaomi Auto after-sales service center for a comprehensive inspection and maintenance before and after track driving to ensure the vehicle's condition and safety. We also advise that you fully understand the vehicle's performance before track driving, participate in professional driving training, and thoroughly master the professional knowledge and rules of track driving. In addition, please pay extra attention to the following aspects:

Braking System: On the track, vehicles need to brake frequently and forcefully, which accelerates the wear of brake pads. At the same time, long periods of intense driving generate significant heat in the braking system. Frequent high-temperature environments can degrade the performance of brake fluid, affecting braking efficiency. The Xiaomi SU7 Ultra comes standard with carbon-ceramic brake discs across all trims, which not only resist high temperatures and prevent brake fade but are also extremely wear-resistant, offering a lifespan far exceeding that of steel brake discs even under intense track driving.

Tires: On the track, vehicles accelerate, decelerate, and corner at high speeds frequently, generating significant lateral and longitudinal forces on the tires. This leads to accelerated wear of the tire tread, especially on the outer edges and center. The high temperature generated by friction between the tires and the ground during track driving accelerates the aging of tire rubber, reducing its elasticity and making it prone to cracking and hardening. The tires used on the Xiaomi SU7 Ultra are custom-made for the vehicle's performance by the factory, significantly reducing these risks. We recommend choosing original factory tires when replacing them; otherwise, handling and durability may be greatly reduced.
