4 TECHNOLOGY PERFORMANCE 4.1 Energy consumption The energy consumption metric evaluates the sales-weighted average certified energy consumption of BEVs sold by each manufacturer. Energy consumption measures the amount of energy consumed per distance traveled. For vehicles with the same battery size, the more efficient vehicle can drive longer distances per charge. BEVs that consume less energy consume less electricity and have lower upstream emissions from vehicle use. Vehicles that consume less energy also reduce energy costs for operators. Additionally, with lower energy consumption, the same range can be achieved with a smaller battery, and that can lower vehicle cost. METHODOLOGY We computed the energy consumption of each BEV model in our database by dividing the net (usable) battery capacity by the certified driving range, expressed in Wh/km. The resulting energy consumption values were usually lower than the rated energy consumption reported to regulatory agencies, which accounts
