The Vehicle Technologies Office's Advanced Vehicle Testing Activity carries out testing on a wide range of advanced vehicles and technologies on dynamometers, closed test tracks, and on-the-road. These results provide benchmark data that researchers can use to develop technology models and guide future research and development. The following set of reports (part of the medium and heavy-duty truck data) describes data collected from testing on FedEx Express and UPS hybrid-electric delivery trucks developed by Azure Dynamics. This research was conducted by the National Renewable Energy Laboratory (NREL).
