1. A vehicular exterior door handle assembly, the vehicular exterior door handle assembly comprising:
a base portion disposed at a door handle region of a vehicle door;
a handle portion including a base end and a grasping portion;
wherein the handle portion is movable relative to the base portion between a recessed position, where the grasping portion of the handle portion is recessed at the base portion and not graspable by a user, and a deployed position, where the grasping portion of the handle portion protrudes outward from the base portion and is graspable by the user;
an actuator, the actuator comprising (i) an electrically-operable motor, (ii) an output element mechanically coupled to the handle portion, and (iii) a variable drive element coupled to the electrically-operable motor and the output element;
a connection connected between the electrically-operable motor and the variable drive element;
wherein the electrically-operable motor is electrically operated in response to an input signal;
wherein the actuator, when the electrically-operable motor is electrically operated, drives the variable drive element to move the output element;
wherein the actuator, when the electrically-operable motor is electrically operated, moves the output element to move the handle portion between the recessed position and the deployed position;
wherein, when the electrically-operable motor is electrically operated to move the handle portion from the recessed position toward the deployed position, the connection is engaged so that the connection limits the output element to move at a first speed to move the handle portion from the recessed position toward a partially deployed position; and
wherein, when the electrically-operable motor is electrically operated to further move the handle portion from the partially deployed position toward the deployed position, the connection is disengaged so that the output element moves at a second speed that is faster than the first speed to more rapidly move the handle portion from the partially deployed position toward the deployed position.
