Chinese heavy truck manufacturer SANY has confirmed that it is preparing for mass production of its fourth-generation autonomous electric semi-truck, with the first units expected to roll out within the next year. Developed in partnership with autonomous driving specialist Pony.ai, the new platform introduces a pragmatic approach to automation aimed at overcoming regulatory and operational barriers.
Rather than deploying fully driverless vehicles across public roads, SANY and Pony.ai are promoting a “1+4” platooning model. In this configuration, a human-driven lead truck is followed by four autonomous trucks that operate in synchronisation. The concept is designed primarily for controlled environments such as smart ports, logistics hubs and drayage routes, where predictable traffic patterns and fixed routes reduce risk.
The fourth-generation truck is built on a battery-electric platform and features a 400 kWh swappable battery pack, supported by regenerative braking. From a technical standpoint, the vehicle is equipped with a fully redundant drive-by-wire chassis covering steering, braking, power supply, communication, computing and sensor systems. Radar and camera arrays provide the foundation for autonomous operation, while the entire system has undergone extreme-temperature and electromagnetic compatibility testing to meet freight safety requirements.
Pony.ai has indicated that the Gen-4 system uses 100 percent automotive-grade components, cutting bill-of-materials costs by roughly 70 percent compared to earlier generations. The platform is designed for a service life of up to one million kilometres, with fleet-scale deployment expected from 2026.
Trial operations suggest that the human-led platoon model can reduce freight costs per kilometre by approximately 29 percent, while improving operating profit margins by nearly 195 percent. Carbon emissions are also expected to drop significantly, aligning with China’s broader push towards intelligent, low-carbon logistics.
While autonomous trucking remains some distance from widespread open-road use, especially given ongoing global scrutiny around systems such as Tesla’s driver-assist technologies, SANY’s approach demonstrates how incremental automation could deliver real efficiencies without waiting for full autonomy. For markets like South Africa, where regulation, infrastructure and labour considerations remain complex, the model offers a glimpse into how automation may first enter heavy-haul operations in controlled, high-volume freight environments.
