Hainan Automobile Proving Ground in China Tests Vehicles on Rough Terrain and Simulated Water Crossing

Key summary

The Hainan Automobile Proving Ground in southern China conducts durability tests on vehicles across rough roads, gravel, mud, wave-simulated surfaces, and water crossing areas. The facility evaluates structural integrity, suspension, components, performance, stability, and handling at high speeds. High temperatures, humidity, and heavy rainfall in the region allow testing of heat and moisture impacts on materials and systems, including corrosion risks, which is relevant for markets like Southeast Asia and Thailand. The site includes a 9-kilometer Strengthened Durability Road with 14 simulated surface types covering 27 road conditions; a 6-kilometer High-Speed Circuit Track with a maximum straight section of 2.2 kilometers and a design speed of 250 km/h, featuring banked curves up to 52 degrees; and areas for gravel, mud, wave, and water driving simulations. Major domestic and international brands such as Tesla and Xiaomi use the facility, which sees approximately 10,000 vehicles tested annually. As the industry shifts to electric vehicles (EVs), testing now covers battery management systems, electric motors, power control systems, cooling systems, and software, including autonomous driving functions like lane-keeping assist, object detection, and traffic sign recognition. China operates a broader network of test tracks in regions with different climates, such as Changchun and Hulunbuir for cold weather testing, and Yancheng and Ningbo, to evaluate vehicles under varied temperature, humidity, and road conditions before market launch.
