Motor driven toy vehicles which may assume the form of different vehicle bodies, each having a chassis with a base-plate at the bottom thereof provided with a generally rectangular opening into which may be inserted different and interchangeable module casings containing drive mechanisms for the vehicles. These mechanisms may assume different forms although they are composed essentially of a small direct-current motor, a dry cell for energizing the motor and a switch mechanism for controlling the connections therebetween. One embodiment of module makes possible the movement of the vehicle in forward and backward directions from a position of rest. Another embodiment permits energization of the motor in a single direction only which compels movement of the vehicle in diverse and haphazard directions by combining the steering control for the vehicle with the traction drive therefor.
