Do not leave long-distance HEVs until after arrival. After arrival, remediation options, negotiating leverage, and time are all more limited, allowing rated specifications that diverge from actual routes, loads, and refueling or charging conditions to become storage costs, delays, or customer complaints. Before shipment, verify records for duty-cycle mileage, roads, climate, load, and idle windows. Put unconfirmed items on an exception list and decide whether to accept them based on the requirement to explain CLTC, WLTP, and other test cycles side by side and assess real-world performance under operating conditions.
