What is the "24-Hour Endurance Challenge"? Why conduct a "24-Hour Endurance Challenge"?

Question

Introduction to the rules of the 24-Hour Endurance Challenge and its purpose of verifying the vehicle's comprehensive performance.

Accepted Answer

The "24-Hour Endurance Challenge" draws inspiration from the 24 Hours of Le Mans. It involves a vehicle driving continuously at high speeds on a closed test track circuit with "drivers changing but the car remaining the same." The time spent charging is also included within the 24-hour period, and the final result is the total distance the vehicle can cover.
Such a challenge is equivalent to "running a marathon at sprint speed." It places immense demands on the vehicle's technical capabilities in areas such as the electric drive system, battery, and thermal management. The core aspects include:
Whether the electric drive system can maintain ultra-high speeds while keeping energy consumption low;
Whether the power battery can consistently ensure charging/discharging power and efficiency;
Whether the cooling system can guarantee temperature control under extreme operating conditions;
Whether the vehicle's aerodynamic design can minimize the impact of wind resistance on energy consumption, among others.
The new generation Xiaomi SU7 Max test vehicle underwent the "24-Hour Endurance Challenge." Through intense testing far beyond daily driving conditions, it verified the vehicle's comprehensive abilities, including performance, range, energy consumption, and reliability. This ensures that future mass-produced vehicles will deliver stronger performance, longer range, and a more reliable user experience.
