The Evolution of the Stelato S9 and S9T: Huawei and BAIC’s Flagship Luxury Electric Duo
The Stelato S9 and its wagon variant, the S9T, represent one of the most technologically advanced entries into China’s modern full-size electric vehicle segment. Developed under the Stelato brand, a joint venture between BAIC BluePark and Huawei’s Harmony Intelligent Mobility Alliance (HIMA), these models were designed to compete directly with global luxury sedans and high-end electric wagons.
The Stelato S9 was officially launched in 2024, followed by the debut of the S9T wagon in 2025, marking Huawei’s first entry into the luxury station wagon segment. Together, they form a flagship product line that combines advanced electrification, range-extender technology, and Huawei’s extensive autonomous driving and digital ecosystem.
Origins of the Stelato Brand
The Stelato brand was created as part of Huawei’s broader automotive strategy under HIMA, which collaborates with multiple Chinese automakers to produce smart EVs. In this case, Huawei partnered with BAIC Group, one of China’s major state-owned automakers.
Unlike traditional automakers, Huawei does not manufacture vehicles directly. Instead, it supplies:
- Smart cockpit systems (HarmonyOS-based)
- Advanced driver assistance systems (ADS)
- Sensors, LiDAR, and autonomous driving software
- Vehicle design and digital architecture integration
BAIC handles vehicle engineering, production, and assembly, primarily at facilities in Beijing.
The Stelato S9 was conceived as a full-size luxury executive sedan, while the S9T expanded the lineup into the increasingly popular premium wagon segment in China.
