MOTOR VEHICLE

A motor vehicle is described (11), propelled by an internal combustion engine or by a hybrid engine, comprising means for the recovery of part of the energy employed in its travel. Said energy is employed in the production of compressed air, to be stored and/or used in activities connected with the vehicle (11) itself. [0002] According to a first embodiment, the electric energy produced by the transformation of said compressed air is used for supplying an electric motor which acts, in assistance to internal combustion engine (15), on differential gear (14). [0003] According to a second embodiment, on an idle axle an electric motor (21) can act, powered by the electric energy produced by the cogenerator (10).
