Q: How was the “24 – hour endurance challenge” of the new – generation SU7 Max test vehicle completed?
A: The “24 – hour endurance challenge” was carried out from 22:10 on November 20, 2025, to 22:10 on November 21, 2025, at the Yancheng Automobile Test Field of China Automotive Technology and Research Center (the test temperature was 0 – 15°C). A new – generation SU7 Max test vehicle continuously drove for 24 hours (including charging time) at a super – high speed of 240 km/h on the high – speed circular track of the test field in the form of “changing people but not the vehicle”. During the whole challenge, the new – generation SU7 Max test vehicle was charged 44 times, and each charging took only about 8 – 10 minutes, ultimately achieving an excellent result of 4,264 km. Throughout the process, the Xiaomi super motor V6s Plus with a maximum speed of 22,000 rpm always maintained an output power of 135 kW and a speed above 18,000 rpm. Even in the second half of the challenge, its power and speed did not decline, showing strong and long – lasting performance and excellent energy – efficiency performance.
