On April 3, 2025, YBCSA received a letter of guarantee for the submission of intermediate shaft parts for the M9 project approved by the customer. This marks another win for the company in the field of high-end electric vehicles.

As we all know, the high-end electric vehicle brand of HarmonyOS represented by Wenjie is developing rapidly, with high recognition from end customers and broad market development prospects. As the company's key development customer, the M9 project had received great attention from the company's leaders at the beginning of the project. The brand had extremely strict requirements for supplier quality control, and because this project was a B point development project, the customer had put forward more stringent requirements for YBCSA than A point suppliers in terms of R&D, quality, service and cost. The entire project team completed the development process from supplier certification, sample production, test evaluation, and output pull in 7 months, and at the same time comprehensively optimized the company's traceability management, incoming material management, and on-site management.

With the mass production of mid-to-high-end projects such as TSL, Cadillac, Zeekr and Wenjie, it means that YBCSA's products have been widely recognized by the automotive industry. This has laid a solid foundation for the company to further internationalize.
