Thirty-Six Month Evaluation of UPS Diesel Hybrid-Electric Delivery Vans
This report focuses on a parallel hybrid-electric diesel delivery van propulsion system currently being operated by United Parcel Service (UPS). The hybrid propulsion system is an alternative to the standard diesel system and allows for increased fuel economy, which ultimately reduces petroleum use. This 36-month evaluation used six P70H hybrids and six P70D standard diesels that are located in two UPS facilities in the Phoenix, Arizona area. Dispatch and maintenance practices are the same at both facilities. Global Positioning System logging, fueling, and maintenance records are used to evaluate the performance of these hybrid step delivery vans. The hybrids had an average monthly mileage rate that was 18% less than that of the diesel vans. The hybrids were consistently driven a fewer number of miles throughout the evaluation period, but they also experienced extended downtime late in the first year as a result of an accident and Eaton calibration issues. The hybrids spent more time idling and operating at slower speeds than the diesels did, and the diesels spent slightly more time operating at greater speeds; this accounted for much of the hybrids’ fewer monthly miles. Other data in this report includes: fuel economy, maintenance costs, fuel costs, operating costs, and reliability.
