SYSTEM FOR DISPLAYING FUEL EFFICIENCY OF VEHICLE ON TERMINAL AND METHOD THEREOF

A system for displaying fuel efficiency of a vehicle on a terminal and a method thereof are provided. The system for displaying fuel efficiency on a terminal, includes: a vehicle terminal calculating average fuel efficiency of a vehicle using vehicle data; and a vehicle information center averaging average fuel efficiencies of respective vehicles of the same vehicle type when the average fuel efficiencies of a plurality of vehicles are received from respective vehicle terminals of the plurality of vehicles to calculate and transmit a reference average fuel efficiency to each of the respective vehicles, in which the vehicle terminals compare the average fuel efficiencies with the reference average fuel efficiency and display the comparison result on a screen, respectively.
