Notes: Chart and description have been changed to reflect Electric Vehicle Efficiency Ratio of 2021 LDV in the United States by Vehicle Class
The Electric Vehicle Efficiency Ratio (EVER) provides a measure of how much more energy efficient (on a mile per gasoline gallon equivalent basis) a BEV is compared to a gasoline internal combustion engine (ICE) vehicle. Excluding vehicles from vehicle size classes without a market available BEV option limits the comparison to more similar vehicles. More detailed comparisons by class provide a more precise efficiency ratio for each class. This does not include light-duty trucks or vans. On-road EVERs are calculated by weighting EVERs by vehicle registrations. Overall, all-electric vehicles are shown to be about 4.4 times more efficient than gasoline ICE vehicles on a combined drive cycle. The efficiency benefit is most pronounced in city driving, where the efficiency benefit reaches 5.1 overall. The overall EVER is most influenced by the midsize car and small sport utility vehicle classes with the highest concentrations of electric vehicle registrations.
