The Xiaomi SU7 Breaks an Endurance Record

The Xiaomi SU7 Max sets a new world record for range over 24 hours for a production electric car.
The electric sedan from Xiaomi, the SU7, has made a strong impact. During an endurance test, the SU7 Max version covered 4,264 km in 24 hours, establishing a world record for a production electric car. This is not just a number; it proves that mainstream electric vehicles can now combine power and range.
The test took place on a 7.8 km oval track in Yancheng, China. Despite a high average speed on the track, exceeding 240 km/h, the SU7 Max showed impressive consistency. The key to the record is, of course, the rapid charging, which allowed for short and non-penalizing stops.
To put this record in perspective, the Mercedes-AMG GT XX concept achieved 5,479 km, but it is not yet a production model, and its launch is not expected until mid-2026 at the earliest. Its price is also expected to be ten times that of the SU7. This makes Xiaomi’s achievement even more impressive for an accessible car.
Technology in Service of Range
Behind this record lies a true technical feat with a 101.7 kWh battery paired with a 897-volt architecture and an advanced thermal management system. Equipped this way, the SU7 Max can recover up to 670 km of range in just 15 minutes thanks to its ultra-fast charging, a performance that was key to maintaining such a hectic pace.
According to the Chinese CLTC cycle, the SU7 Max achieves 902 km. In European WLTP standards, this corresponds to just over 750 km, placing this sedan among the market leaders for public vehicles.
