A method provides a sequence of travel instructions that reports fuel-efficient routes calculated with regard to vehicle specifications, geography of terrain, and complexity of travel route. An operator selects the desired starting and ending location via a client interface of a software application. When the user selects "most fuel efficient route," the fuel-efficient route (FER) utility of the application prompts for entry of the make, model, and year of the operator's vehicle. If the FER utility is embedded in an in-car navigation system, the information about the vehicle characteristics is preprogrammed during installation (e.g., at the factory). The FER utility uses a number of metrics and the vehicle's characteristics, to generate an optimal route for efficient fuel consumption. The invention provides means for an operator of a route planning application to optimize the driving directions for optimally predicted fuel usage.
