Xiaomi EV Road Simulation Lab: 3 Weeks of Testing Equals 300,000 km of Real-World Driving

Xiaomi Chairman Lei Jun recently introduced that Xiaomi’s Wheel-Coupled Road Simulation Laboratory—also known as the Four-Post Test Facility—can accurately replicate various rough road conditions indoors, including Belgian pave, speed bumps, and washboard roads, to validate the structural durability of entire vehicles. The lab is equipped with four hydraulic shakers, each delivering up to 5 tons of force, and integrates a rapid-switching thermal chamber capable of cycling between -40°C and 60°C, along with a solar simulation system, enabling accelerated fatigue testing under extreme climatic conditions. In just two to three weeks, the facility can simulate the equivalent damage of 300,000 kilometers of real-world driving, significantly shortening development cycles and enabling early identification of potential risks. To date, Xiaomi has built over 100 in-house laboratories in Beijing, Shanghai, Nanjing, and Wuhan. Additionally, the company conducts extreme-environment testing in Turpan, Heihe, Kunlun Mountains, and Hainan, and operates two full-vehicle test tracks in Guangde, Anhui, and Yancheng, Jiangsu, supported by a testing team of more than 800 engineers.
