The Sanyou automobile brand is associated with several different companies. First, Zhejiang Sanyou Group is a diversified company involved in various fields such as motorcycles, plastic pipelines, and woolen textiles, and it launched a vehicle travel recorder in 2004, marking Sanyou Group's entry into the high-tech industry. Additionally, Changchun Sanyou Automobile Co., Ltd. was an enterprise that once existed; it was a joint venture with Thailand's Sammitr company to produce motor vehicle parts and manufactured some models in the 1990s, such as the CY6500 station wagon and CY1020 pickup truck based on the Nissan D21 pickup. These models were priced high at the time but ultimately Sanyou Automobile transitioned into a motor vehicle parts manufacturer. Furthermore, Sanyou Holding Group Yinyou Motorcycle Co., Ltd. is a motorcycle manufacturing enterprise with brands such as "Sanyou," "Sanyou," and "Kadhibao," offering motorcycle research and development, manufacturing, sales, and services. There is also information showing that electric vehicles produced by Sanyou Holding Group officially entered mass production after testing, including a series of products such as Leku, Ruiguan, Ruiying, Xingtu, Xingguang, and Xingyao. This information indicates that the "Sanyou" brand has multiple different business directions and product lines in the automobile and motorcycle industries.
