What is an eGallon?
An eGallon is a fuel cost comparison between an electric vehicle (EV) and a gasoline vehicle.

Did you know?
It costs about half as much to drive an electric vehicle as a gasoline powered vehicle.

Data and Methodology:
The eGallon represents how much it would cost to drive an EV the same distance as a conventional vehicle on one gallon of gasoline.

An eGallon is calculated by multiplying the cost of electricity or the electric price (EP) by the average comparable passenger car adjusted combined fuel economy (FE) by the average fuel consumption of popular electric vehicles (EC). 
eGallon ($/gas) = FE X EC X EP
