How was the "24-Hour Endurance Challenge" for the new generation SU7 Max test vehicle specifically completed?
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 generation SU7 Max test vehicle charged 44 times, with each charging session lasting only about 8-10 minutes, ultimately achieving an excellent result of 4,264 km.
Throughout the process, the Xiaomi HyperEngine V6s Plus super motor, with a maximum speed of 22,000 rpm, maintained an output power of 135 kW, with the rotation speed consistently staying above 18,000 rpm. Even in the latter half of the challenge, its power and rotation speed showed no decay, demonstrating strong, enduring performance and excellent energy efficiency.
