Xiaomi SU7 Max Sets Fastest Lap for Sub-¥500K Four-Door Production Car at Zhejiang Circuit

The Xiaomi SU7 Max set a new lap record at the Zhejiang International Circuit with a time of 1:37.974, becoming the fastest mass-produced four-door car under RMB 500,000 and ranking fifth among all mass-produced four-door cars on the circuit’s official leaderboard. The test vehicle was a production-spec SU7 Max fitted only with three optional high-performance components from Xiaomi’s original equipment lineup: Sailun PT01 high-performance tires, ITT high-performance brake pads, and ENDLESS RF650 high-boiling-point brake fluid. All other aspects of the car remained in standard factory condition. These performance upgrade parts are now available for purchase: the high-performance tires start at RMB 2,250 per tire, and the brake kit—including labor—costs RMB 4,133. Xiaomi has simultaneously opened official channels for customers to buy and install these performance packages according to their preferences.
