When selecting a hybrid truck, you must prioritize the Powertrain Architecture (Parallel, Series, or Power-split) and Battery Capacity (kWh). Ensure the vehicle features a High-Efficiency Internal Combustion Engine (ICE) paired with a robust Electric Motor. Key metrics include the Payload Capacity, Gross Vehicle Weight Rating (GVWR), and the Regenerative Braking Efficiency. For long-haul operations, verify the Fuel Consumption Rate in Hybrid Mode and the Pure Electric Range for urban 'last-mile' compliance.
