A method, system, and apparatus are provided for optimizing control of the rotational speed of a fan in a vehicle so as to reduce the aerodynamic drag of a vehicle in a given operating parameter, and accordingly, to improve fuel efficiency of operation of the vehicle. Certain exemplary embodiments include determining an optimized speed of rotation of a cooling fan of the vehicle for reducing overall fuel demand in given operating conditions, and controlling rotation speed of the fan at the optimized speed in order to minimize fueling demand of a prime mover of the vehicle.
