- Tractor Unit Mechanics: For a tractor unit, the "Max Loading Capacity" (最大载重) refers to the GCW (Gross Combined Weight)—the total weight of the tractor, the semi-trailer, and the cargo combined. The GVW (53,000 kg) is the maximum weight allowed on the tractor's own axles.
- Configuration Differences:
- Option A : Lighter setup (6T front, 13T rear axles, 262.75 kWh battery, 10,200 kg curb weight) with a 40-ton towing capacity and 140 km range. Better for short, heavy port shuttles.
- Option B : Reinforced setup (7T front, 16T rear axles, 400.61 kWh battery, 11,215 kg curb weight) with a 46-ton towing capacity and 200 km range. Better for regional heavy freight and longer distances.
