How can consumers compare the energy consumption of different electric vehicle models?

Consumers can compare the energy consumption of different electric vehicle models by using the EPA's efficiency ratings. The Environmental Protection Agency evaluates electric vehicles based on their energy consumption metrics, typically expressed in miles per gallon of gasoline equivalent (MPGe) or kilowatt-hours per 100 miles (kWh/100 mi). These ratings provide standardized and objective information that allows consumers to assess how efficiently each vehicle uses energy to travel a certain distance.

This method of comparison is particularly valuable because it considers various factors including the vehicle's technology, battery size, and aerodynamics. As a result, consumers can make informed decisions based on quantifiable data rather than subjective marketing messages. The EPA ratings also allow for a consistent benchmark across different models, facilitating easier comparisons.

The other options do not provide the same level of reliable information for comparing energy consumption. Manufacturer marketing materials can be biased or selective in presenting features that may not accurately reflect efficiency. Checking the vehicle's weight could provide some insights into efficiency but does not give a direct measure of energy consumption per distance traveled. Similarly, the maximum speed of an electric vehicle does not correlate directly with energy efficiency and does not help in evaluating how much energy the vehicle uses for everyday driving.
