- Vehicle Type: This is an Electric Tractor Unit (纯电动牵引车), designed to pull semi-trailers.
- Weight & Towing: The GVW (25,000 kg) is the weight of the tractor itself plus the load on its own axles. The Max Loading Capacity (55,000 kg) in this context refers to the GCW (Gross Combined Weight)—the total weight of the electric tractor plus a fully loaded trailer. The combination of a 400 kW motor and dual 13-ton rear axles makes it highly capable of pulling 55-ton loads.
- Battery & Range: Powered by a huge 400.61 kWh CATL battery, giving it a range of 220 km. This is an ideal setup for regional logistics, port drayage, or short-haul distribution where heavy trailers need to be moved efficiently, and the truck can fast-charge at the hub.
- Tires: Equipped with 12.00R22.5 tires, which are standard heavy-duty commercial tires used on highway tractors and trailers.
