On November 20–21, 2025, Xiaomi EV revealed endurance test results for its next-generation Xiaomi EV SU7 Max as the updated electric sedan prepares for its official market launch in April. The test establishes a new milestone for mass-produced electric vehicles under comparable conditions.
The Xiaomi EV SU7 Max achieved a total driving distance of 4,264 kilometers during a continuous 24-hour endurance test. This result sets a new record for production vehicles, exceeding the earlier benchmark of 3,961 kilometers established by the updated P7 model from Xpeng in August last year.
Xiaomi EV SU7 Max Performance Compared With Global Benchmarks
In similar endurance evaluations, the 2019 Taycan from Porsche covered 3,425 kilometers, while the 2024 CLA from Mercedes-Benz achieved 3,717 kilometers. A higher figure was recorded by the Mercedes-Benz AMG GT XX concept car, which completed 5,479 kilometers in an endurance test conducted in August 2025.
During the Xiaomi EV test, the vehicle operated continuously for 24 hours, including charging time, to push the maximum achievable range. The sedan reached speeds of up to 240 kilometers per hour during the run, emphasizing sustained high-load performance rather than efficiency-focused driving alone.
“It’s like running a marathon at sprint speed,” Xiaomi founder, chairman, and CEO Lei Jun said on Weibo on Monday.
Xiaomi EV SU7 Max Powertrain, Battery, and Charging Details
The Xiaomi EV SU7 Max used in the test is equipped with Xiaomi’s V6s Plus motor, capable of spinning at 22,000 rpm and supporting a top speed of 265 km/h. The vehicle is built on an 897-volt silicon carbide high-voltage electric platform designed for sustained high-performance operation.
Battery specifications include a 101.7-kWh ternary lithium battery pack. The system supports a peak charging rate of 5.2C and delivers a CLTC-rated range of 835 kilometers per charge under standard testing conditions.
Xiaomi completed the endurance test between 10:10 pm on November 20, 2025, and 10:10 pm on November 21, 2025, in Yancheng, Jiangsu province, eastern China. According to Lei Jun, the SU7 Max uses the same thermal management system as the higher-priced SU7 Ultra, enabling a 15-minute charge to add up to 670 kilometers of driving range.
