Vehicle propulsion system or the like characterized by energy interchange between a plurality of flywheel assemblies each including a driving/driven induction motor/generator, and a plurality of vehicle drive wheel assemblies including drive wheels each directly driving/driven by an induction motor/generator, with energy makeup provided by a heat engine driven generator means, operated on demand, such energy interchange being by means of a multi-directional bus to which the flywheel and drive wheel motor/generators are selectively connected by variable frequency switch means and to which the engine driven generator is connected when operating, the switching being under control of a digital computer type controller, the controller receiving as inputs various vehicle operating conditions including flywheel, drive wheel, brake, steering angle and speed control positions, and bus voltage and heat engine driven generator operating condition, and the controller generating switch means controlling outputs causing energy transfer from or to the bus and to or from the drive wheel motor/generators to accelerate or decelerate the vehicle responsive to operator inputs, and causing energy transfer from or to the bus and to or from the flywheel motor/generators when the bus voltage is greater than or less than a predetermined value and to maintain the flywheels at substantially equal rotational speeds, and operating the heat engine and cause electrical energy transfer from the engine driven generator means to the bus whenever the total energy available from the motion of the vehicle and the kinetic energy of the flywheels is less than a predetermined value.
