Li Auto Inc. Appoints Chief Technology Officer

BEIJING, China, September 15, 2020 — Li Auto Inc. (“Li Auto” or the “Company”) (Nasdaq: LI), an innovator in China’s new energy vehicle market, today announced the appointment of Mr. Kai Wang as chief technology officer (“CTO”) effective September 15, 2020. In this role, Mr. Wang is responsible for providing overall leadership in advanced technology research and development in intelligent vehicles, including electronic and electrical architecture, intelligent cockpit, autonomous driving, platform development and Li OS, the real-time operating system of Li Auto.

Mr. Wang has 18 years of experience in research and development and management of core technologies in automotive and mobile phone industries. He is a world-renowned expert in the field of automotive electronic and electrical architecture, domain controller, intelligent and connected automotive technologies, and autonomous driving. Prior to joining Li Auto, Mr. Wang worked for Visteon Corporation for 8 years. In his last role as Visteon’s global chief architect and director of advanced driver assistance systems (“ADAS”), he was responsible for establishing and maintaining technology roadmaps covering both hardware and software disciplines. Mr. Wang was a key contributor of SmartCore™, the world’s first production cockpit domain controller, and DriveCore™, an open and extensible autonomous driving platform. In addition, since 2019, Mr. Wang has been an adjunct professor in the Automotive Institute of Tongji University in China.

“We expect rapid and forceful development in the automotive industry over the next five years, with revolutionary changes potentially overshadowing all the changes this industry experienced over the past century. As an automotive and technology company, we understand the crucial necessity for a top-notch CTO to drive the overall architectural vision for our vehicles and coordinate its implementation, all to ensure that we maintain our leadership position in the coming rounds of competition,” said Mr. Xiang Li, founder, chairman, and chief executive officer of Li Auto. “Kai is a first-class architect with not only comprehensive and deep expertise but also practical experience in the fields of chipsets, automotive systems, software, electronic and electrical architecture, intelligent cockpit, and autonomous driving. He also has forward-looking judgment and thinking on the development of frontier technologies for smart vehicles. His profound expertise and impressive track record make him an ideal choice for this role and we warmly welcome Kai to the team!”

“I am very excited to join Li Auto,” Mr. Wang said. “The automotive industry is undergoing a tremendous transformation from functional vehicles to smart vehicles, and is at the center of the accelerated integration of multiple industries, bringing technological advancement to people’s daily lives. China’s smart vehicle industry, in particular, has experienced rapid development while enjoying supportive regulatory policies as well as a huge end market. As an emerging force in China’s smart vehicle industry, Li Auto has successfully gone from zero to one, championing both a vision and values with which I couldn’t have agreed more. I am optimistic about its future development prospects, and believe the Company will assume an even greater future role in China’s automotive industry. It is a great honor to be a part of this outstanding team, working together toward the realization of our dreams and ideals.”
