The invention relaxes to a transport technical field and more precisely to power plants of cars and trucks arid may be used as a power plant of buses, motorcycles, electro-mobiles, in rolling stocks (electromotive, locomotive, carriage, van, etc.), metro, tram, trolleybus, in water-borne transportation and in air transport as well as for 2 creation of local power stations. The declared invention is characterized in that a combined aerodynamic power-plant (CAPP) in a vehicle motion generates by means of incoming air flow an electric energy and distributes it between the vehicle wheels. A quantity of the energy generated in air units of the power plant CAPP makes up not less than 50% of energy necessary and sufficient for uniform rectilinear motion of the vehicle. The construction of the power plant CAPP is smoothly combined with modern standard vehicles and with their power plants both in the electro-mobiles and the vehicles with hybrid power plants essentially improving their technical and ecological characteristics.
