Insights
Hesai's selection for Didi and GAC Aion's L4 Robotaxi represents a significant commercial validation for the company's lidar technology in the autonomous vehicle market. The announcement that each vehicle will incorporate four AT128 sensors is particularly notable, as it establishes a substantial per-vehicle revenue opportunity for Hesai.
The technical specifications highlighted are impressive – the AT128's
What makes this announcement particularly concrete is the defined timeline: mass production beginning this year (2025) with deployment in 2026. This clear commercialization roadmap differentiates this deal from conceptual partnerships that lack definitive production commitments.
The partnership with Didi, China's largest mobility platform, and GAC Aion, a subsidiary of one of China's major automakers, provides Hesai access to potentially significant deployment scale. While financial terms and production volumes remain undisclosed, limiting quantification of revenue impact, securing a position in what appears to be China's first mass-produced L4 robotaxi establishes Hesai as a leader in the high-end autonomous vehicle sensor market.
This partnership marks a critical milestone in autonomous vehicle commercialization. The selection of Hesai's AT128 for what's described as the "first L4 production-ready Robotaxi" by Didi and GAC Aion signifies the technology's maturation from experimental to commercially viable.
The multi-sensor architecture (four lidars among 33 total sensors) reinforces that L4 autonomy requires redundant, high-performance perception systems. Hesai's prominent position within this architecture – providing the primary 3D sensing capability – secures its role in the autonomous driving stack.
Particularly noteworthy is the transition to actual production. While many AV companies announce partnerships and prototypes, this announcement specifically commits to mass production in 2025 with deployment beginning in 2026. This concrete timeline suggests the technology has passed rigorous testing and validation phases.
For context, L4 autonomy represents fully autonomous operation within specific operational domains – a significantly more advanced capability than the driver-assistance systems common in today's consumer vehicles. Robotaxis represent the most commercially viable initial application for L4 technology due to their controlled operational environments and service-based business model that can absorb higher technology costs.
While the announcement lacks deployment scale details, securing a position with Didi – which operates China's largest ride-hailing network – provides Hesai with substantial growth potential as autonomous mobility services expand.
The new Robotaxi model features four Hesai AT128 lidar sensors, playing a central role in the vehicle's 360° blind-spot-free perception system. With an industry-leading 1200×128 resolution, the AT128 captures 1.53 million points of data per second, offering detailed and reliable perception in complex and dynamic driving environments. Its long detection range of up to 200 meters, and 120° field of view enable early detection of obstacles, significantly enhancing safety in urban and highway scenarios. The Robotaxi integrates 33 sensors in total, using a heterogeneous sensor fusion architecture to deliver real-time, 360° situational awareness. The deployment of four AT128 lidar sensors enhances depth perception, ensuring safe navigation through complex traffic environments.
"We are honored to support the L4 Robotaxi with our AT128 lidar," said David Li, Co-Founder and CEO of Hesai. "Our collaboration with Didi Autonomous Driving and GAC Aion exemplifies the powerful synergy between advanced lidar innovation and full-stack autonomous driving systems and demonstrates what's possible when cutting-edge lidar technology meets sophisticated autonomous driving systems to transform how people move through the world."
The L4 Robotaxi production model is the result of a multi-year strategic collaboration between Didi Autonomous Driving and GAC Aion. The vehicle combines GAC Aion's globally adaptable safety redundancy platform for L4 autonomous driving with Didi's upgraded hardware platform, multi-layered safety redundancy, and full-stack autonomous driving software.
Hesai remains committed to pushing the boundaries of lidar technology and supporting its partners in achieving safe, scalable, and cost-effective autonomous driving.
