Automotive vehicle of the hybrid-powered type wherein the traction wheels are driven at low speeds by electric energy stored in a battery and at high speeds by an internal-combustion engine simultaneously recharging the battery. The engine, when running, may also load a mechanical force storer, such as an air pressure accumulator, used to assist in the starting of the vehicle to conserve battery power; in the absence of such a stored force, the engine is used for starting and then ceases to operate until a certain minimum speed is reached. |
