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 i…

The severity of the "24-Hour Endurance Challenge" far exceeds daily driving conditions and is currently one of the most extreme scenarios for comprehensively verifying an electric vehicle's "three-electric performance" and "ultimate range." To achieve good results in the "24-Hour Endurance Challenge," the vehicle must possess comprehensive technical capabilities in charging/discharging, heat dissipation, and driving efficiency. Among these, the three-electric technology and performance are cruci…

This "24-Hour Endurance Challenge" took place from 22:10 on November 20, 2025, to 22:10 on November 21, 2025, at the CATARC Yancheng Automotive Proving Ground (the temperature during the test was 0-15°C). A new generation SU7 Max test vehicle, using the "drivers changing but the car remaining the same" format, drove continuously for 24 hours (including charging time) on the high-speed ring road of the proving ground at an ultra-high speed of 240 km/h. Throughout the entire challenge, this new ge…

Before the new generation Xiaomi SU7 conducted the "24-Hour Endurance Challenge," many excellent automakers had already conducted similar challenges. We have listed some results below for your reference (data sourced from public online information). We also welcome more brands to participate in the "Pure Electric Vehicle 24-Hour Endurance Challenge" to jointly promote the development of the automotive industry! Porsche Taycan (2019): 3,425 km Mercedes-Benz CLA (2024): 3,717 km Xiaomi YU7 (2025):…

The new generation SU7 Max (test vehicle) achieved an impressive result of 4,264 km in the "24-Hour Endurance Challenge." This performance is inseparable from the continuous "technological breakthroughs" and "design optimizations" by Xiaomi Auto engineers, as well as the upgrades in the new generation SU7 Max, which features an 897V silicon carbide (SiC) high-voltage platform, the Xiaomi HyperEngine V6s Plus super motor, and a 101.7kWh ternary lithium battery, delivering stronger power, longer r…

When the ambient temperature or tire temperature is low, the front wheels may sometimes emit a "clunk" sound when performing sharp turns during low-speed parking maneuvers. This is usually a normal manifestation of the steering system's "Ackermann angle" design under cold conditions, so there is no need to worry. The "Ackermann angle" design refers to the difference in steering angles between the two front wheels when the vehicle turns, designed to make the turn smoother and more precise (typica…

After the official launch of the new generation SU7, users who placed a small deposit and convert to a firm order and lock their configuration within the "benefit validity period" will enjoy priority production scheduling. The "benefit validity period" refers to a period of time after the launch during which converting to a locked order will grant priority production scheduling. The specific validity period will be announced when the new generation SU7 is officially launched. In addition, when u…
