Abstract

An energy test method configured to determine fuel consumption of a vehicle is disclosed. The method includes the steps of installing at least one sensor on the vehicle; connecting the at least one sensor to a data recorder; running a baseline test lap on a pre-determined circuit; using the data recorder to record data from the at least one sensor while running the baseline test lap; modifying the vehicle; running a modified test lap on the pre-determined circuit; using the data recorder to record data from the at least one sensor while running the modified test lap; and calculating a fuel savings between the modified test lap and the baseline test lap.
