Horizon Robotics Unveils Cabin-and-Driving Integrated Chip 'Stellar'

[Technical Breakthrough] Horizon Robotics will launch China's first cabin-and-driving integrated chip, 'Stellar,' reducing vehicle costs by RMB 1,500–4,000 per unit.

Key Development: Cabin-and-Driving Integrated Chip 'Stellar' to Launch on April 22

At the High-Level Forum on Intelligent Electric Vehicle Development (2026), Yu Kai, Founder and CEO of Horizon Robotics, revealed that the company will unveil China’s first cabin-and-driving integrated AI chip, 'Stellar,' on April 22. The chip consolidates computing tasks previously requiring two separate domain controllers and memory systems, enabling seamless integration of intelligent cockpit and autonomous driving functions, and cutting costs by RMB 1,500 to 4,000 per vehicle.

Key Metrics: Nearly 50% L2 Market Share, 4 Million Units Shipped in 2025

As of 2026, Horizon Robotics has cumulatively shipped 10 million ADAS units, including 4 million units in 2025 alone. It holds nearly 50% market share in the L2 ADAS segment, ranking first, and is among the top three in the NOA market. In 2025, the company invested approximately RMB 5 billion in R&D, and user-driven mileage powered by its HSD large model exceeded 40%, with a target to surpass 50% within the year.

Strategic Foundation: Organizational Integration Aligns with Centralized Computing Trend

Yu Kai emphasized that automotive computing is shifting from distributed architectures toward centralized integration. OEMs must break down the organizational silos between cockpit and autonomous driving teams to drive internal convergence. Horizon Robotics maintains its positioning as an open-ecosystem Tier 2 supplier, with over 95% of its revenue generated through partners.
