Xiaomi’s electric sedan, the SU7 Max, has set a new global endurance record for production electric vehicles. The car covered 4,264 kilometers in 24 hours during a continuous drive-and-charge test.
The test was conducted on a 7.8 km oval track in Yancheng, China. The sedan maintained high speeds—up to 240 km/h—throughout the day, stopping only for brief ultra-fast charging sessions. CEO Lei Jun described the challenge as a “marathon at sprint speed,” highlighting the intense stress on the vehicle’s powertrain and battery.

The result surpasses the previous record of 3,961 km set by the Xpeng Next P7 in 2025. It also outpaces premium competitors like the Porsche Taycan (3,425 km) and the new Mercedes-Benz CLA electric (3,717 km). The distance covered is roughly equivalent to driving from New York to Los Angeles.

Key to the achievement was the car’s advanced thermal management system and 897-volt architecture. This allows its 101.7 kWh battery to sustain extreme performance and recharge up to 670 km of range in just 15 minutes.
The 2026 SU7 Max model features new V6s Plus electric motors capable of 22,000 rpm, a top speed of 265 km/h, and a maximum range of 835 km. Its official launch is scheduled for April 2026, with a starting price in China of $44,500.
