Disclosed is a technique for ranking a driver's fuel efficiency among other drivers based on various variables associated with the environment in which the vehicle is being driven. More particularly, the present invention, selects, as a category, one or more factors affecting fuel efficiency, and, as one or more, variables another one or more. Vehicle data is then collected by a communications device which is associated with a particular trip. Next an average of the fuel efficiencies and an average of the variables for the trip are calculated accordingly the selected one more categories. The fuel efficiency of the trip corresponding to a same category for every coordinate point of the variable is then statistically processed to calculate the average of the fuel efficiency and the standard deviation of the fuel efficiency and regularized (processed as a GAP calculation) to determine the ranking of a vehicle driver.
