WM Motor was established in 2015 and is headquartered in Shanghai. The company name comes from the German "Weltmeister", which means "world champion". WM Motor is committed to the development and production of high-quality, high-performance, and high-intelligence new energy vehicles. Its models include EX5, EX6 and W6. Its products are known for their advantages such as long cruising range, technological innovation and intelligent interconnection, especially in autonomous driving and intelligent hardware.

However, in recent years, the company has experienced many equity freezes and legal disputes, has poor financial conditions, and has even applied for bankruptcy reorganization. In terms of after-sales service, many car owners report insufficient supply of parts and components and difficulty in maintenance, resulting in frequent after-sales problems. In addition, authorized repair centers in some areas can only provide basic maintenance services due to shortage of parts and cannot solve complex problems. These issues have seriously affected user experience and brand reputation.
