Abstract: A vehicle has a roll axis, a pitch axis and a yaw axis and includes a tail portion and a beam fixed at the tail portion and extending according to the pitch axis, characterized by comprising at least two blades hinged to the beam around respective axes parallel to the pitch axis and defining respective faces, so that the blades are rotatable around the axes and selectively movable to a first configuration, in which the faces are arranged so as to be transversal, in use, to an aerodynamic flow of the vehicle along the roll axis, and to a second configuration, in which the faces are parallel to said aerodynamic flow and face one another.

Abstract: A wheel rim having a central axis and comprising a central hub configured to be fixed to a suspension of a vehicle; a peripheral ring, which is arranged around the hub with a predetermined radial distance from the hub itself and is configured to receive a tire of the vehicle on a radially outermost surface thereof; a plurality of spokes equally spaced angularly from one another around the axis and connecting the peripheral ring to the hub; and at least one projection protruding in a cantilever fashion towards the hub, starting from a radially innermost surface of the peripheral ring, opposite to the radially outermost surface, and defining an airfoil configured to generate, in use, during the forward travel of the vehicle, a channelling of the air towards the outside of the wheel rim.

Abstract: A car having: a passenger compartment; a body surrounding the passenger compartment and having: a roof, a tail provided with a rear bumper, and a joining portion connecting the 5 roof to the tail; a rear spoiler, which is arranged at the end of the joining portion in the area of the tail; and a deflector panel, which is arranged on the joining portion, is directly hit by an air flow brushing the joining portion during the travel and is mounted in a movable manner so as 10 to move between a rest position, in which the deflector panel rests on the joining portion, and an active position, in which the deflector panel is lifted and spaced apart from the joining portion.
