When selecting a hybrid van, you must prioritize the Powertrain Configuration (Plug-in Hybrid PHEV vs. Full Hybrid HEV) to match your range requirements. Key specs include Battery Capacity (kWh), which determines the electric-only range, and Payload Capacity, ensuring the chassis can handle cargo weight plus the battery weight. Look for Regenerative Braking Systems to maximize fuel efficiency in urban stop-and-go traffic and verify the Charging Interface Standard (e.g., Type 2 or CCS) for compatibility with your local infrastructure.
