According to auto media including Yiche and Late Auto, Saidou Technology, the all-new EV brand co-developed by Seres and ByteDance’s Volcengine, is scheduled for official release on June 9. Centered on AI-native intelligent vehicles equipped with Doubao large model cockpit, the brand targets young consumers in the new energy vehicle market. Former Chongqing Landian Technology completed its name change to Chongqing Saidou Technology on May 29, establishing the formal legal entity for the cross-industry cooperation.

Compared with Volcengine’s shallow co-development with SAIC Roewe, ByteDance’s technical participation in Saidou reaches an unprecedented depth focusing on in-vehicle large model and intelligent cabin R&D. All upcoming cars adopt Doubao LLM and abandon Huawei Kunpeng intelligent driving solution to build exclusive intelligent features. The brand’s first model is set to launch within 2026 as a cross-over coupe SUV with both BEV and extended-range options for daily urban driving and long-distance trips. Production is arranged at Seres Phoenix Plant, where production line renovation has been finished.

For sales layout, Saidou builds its independent dealership network separated from existing AITO stores and rolls out products for domestic and overseas markets simultaneously. Priced between 100,000 and 200,000 RMB, it forms a complementary product layout with high-end AITO lineup and completes Seres’ full-price-range product portfolio. Chongqing state-owned capital, Seres and CATL hold shares of Saidou; ByteDance takes no equity stake but empowers vehicle development via full-stack cloud and AI technologies, realizing industrial implementation of internet AI. Industry insiders comment that Saidou helps Seres diversify its intelligent driving supply chain while fulfilling ByteDance’s strategy of empowering automakers without manufacturing cars itself.
