Abstract: A method for controlling a powertrain of a hybrid vehicle having an engine, a motor/generator, a battery that is rechargeable using at least one of the engine and the motor/generator, and a powertrain control module (PCM) includes determining a current location of the vehicle as a starting point of a preferred route, recording a user-selected ending point of the preferred route, and processing route information using the PCM to thereby determine an optimally fuel efficient route for reaching the ending point. The method includes automatically executing the powertrain control strategy over the optimally fuel efficient route by substantially depleting a charge level of the battery as the vehicle travels over the optimally fuel efficient route such that the charge level of the battery is depleted when the vehicle reaches the ending point. When the ending point is not recorded, the PCM can default to a charge-sustaining mode.
