1. A method for vehicle route planning as a function of vehicle type, comprising:

  • determining a plurality of different routes for travel by a vehicle from a trip origin to a destination;

    identifying the vehicle as a hybrid vehicle type that generates operative energy through a regenerative braking energy component or an internal combustion engine vehicle type;

    recommending via a programmable device a route of the plurality of routes to an operator of the identified vehicle as a function of the identified vehicle type by;

    determining that traveling a first route of the plurality of routes will result in a faster total travel time to the destination relative to traveling a second route of the plurality of routes;

    determining that traveling the second route will cause more braking by the vehicle relative to traveling the first route;

    recommending the first route over the second route to an operator of the identified internal combustion engine vehicle type for traveling to the trip destination as a function of the faster total travel time;

    recommending the second route over the first route to an operator of the identified hybrid vehicle for traveling to the trip destination as a function of the more braking determination; and

    wherein a route recommended to the identified internal combustion engine vehicle type is different from a route recommended to the identified hybrid vehicle type.
