  6. The motor vehicle according to any one of the preceding claims, wherein the opening device (5) comprises - a motor (10) controllable by the control unit (ECU); and - a pushing assembly (11) operable by the motor (10) to exert a transversal thrust upon the door (4); wherein the pushing assembly (11) comprises - at least one thrust portion (12), which is movable, through translation, along a straight direction (A); - a transmission configured to transmit an output of the motor (10) to the thrust portion (12) so that the thrust portion (12) translates in response to the output of the motor (10), thereby exerting said thrust.
  7. The motor vehicle according to claim 6, wherein the straight direction (A) substantially extends along a forward moving direction of the motor vehicle (1).
  8. The motor vehicle according to claim 6 or 7, wherein the pushing assembly (11) comprises a fixed structure (15) and a curved arm (14), the arm (14) comprising - a first end (14a), which is fixed to the door (4); and - a second end (14b), which is hinged to the structure (15) about a hinge axis (B) transversal to the straight direction (A), wherein the thrust portion (12) is coupled to the arm (14) so that the arm (14) rotates in response to a translation of the thrust portion (12).
  9. The motor vehicle according to any one of the preceding claims, wherein the opening device (5) is controllable to move the door (4) from the open configuration towards the closed configuration.
  10. The motor vehicle according to any one of the preceding claims, wherein the control unit (ECU) is configured to control the opening device (5) so that the door (4) rotates from the open configuration towards the closed configuration.
  11. The motor vehicle according to claim 10, wherein the control unit (ECU) is configured to control the opening device (5) so that the door (4) rotates from the open configuration towards the closed configuration based on a closing request command.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This patent application claims priority from Italian patent application no. 102021000028820 filed on November 12, 2021. TECHNICAL SECTOR The invention relates to a motor vehicle, for example a sports car, and more specifically to a door thereof and to a relative door opening device. PRIOR ART As everybody knows, car doors are manually opened from the outside through a door handle, which usually also includes a manual control, for example a button or a lever, to unlock a lock of the door. Generally speaking, known motor vehicles need to be improved, in particular by increasing door opening comfort, when the door has to be opened from the outside of the motor vehicle, though without jeopardizing the safety of the motor vehicle in case of theft and of the people or objects surrounding the motor vehicle. The object of the invention is to fulfil the need discussed above, preferably in a simple and effective fashion. DESCRIPTION OF THE INVENTION Said object is reached by a motor vehicle as defined in claim 1. The dependent claims define particular embodiments of the invention. BRIEF DESCRIPTION OF THE DRAWINGS Hereinafter, an embodiment of the invention will be described, in order to allow the latter to be better understood, by way of non-limiting example and with reference to the accompanying drawings, wherein: figure 1 is a perspective view of a motor vehicle according to the invention;figure 2 shows, on a larger scale, a detail of the motor vehicle of figure 1;figure 2a is a further perspective view of an area of the motor vehicle comprising a door portion, in particular shown in an open presenter configuration;figures 3 and 4 are further perspective views of the door, in a closed and open configuration respectively, specifically completely open. EMBODIMENTS OF THE INVENTION In figure 1, reference number 1 is used to indicate, as a whole, a motor vehicle. The motor vehicle 1 comprises a body 2 and a plurality of side doors, in particular a front side door 3 and a rear side door 4. Each one of the doors 3, 4 is hinged to the body 2 so that it can rotate around an axis towards a side of the vehicle, in particular the same side where the doors 3, 4 are located, i.e. the side where a user U is shown in figure 1. In other words, the axis is substantially vertical, meaning that the inclination of the axis relative to a vertical direction could range, for example, from 0° to 30°. In figure 1, the doors 3, 4 are shown in a closed configuration. Each one of the doors 3, 4 can rotate between the closed configuration and an open configuration, for example a completely open configuration, like in figure 4. Hereinafter, for brevity reasons, reference will be made to only one of the doors 3, 4, specifically the door 4, assuming that the information disclosed below could be applied, alternatively or in addition, to the door 3. The motor vehicle 1 comprises an opening device 5, schematically shown in figure 1, to open the door 4. The opening device 5 is motorized and is controllable to move the door 4 from the closed configuration towards the open configuration. Furthermore, the opening device 5 also is conveniently controllable to close the door 4, namely to move the latter from the open configuration towards the closed configuration. In other words, the opening device 5 moves the door 4 in an autonomous manner, namely without any intervention of the user U. Besides the opening device 5, the motor vehicle 1 can also comprise a lock device 6 controllable to lock the door 4 in the closed configuration and to further unlock the door 4 locked in the closed configuration. For example, the lock device 6 could be controlled by the user U by means of a remote control not shown herein. In order to operate the opening device 5, the motor vehicle 1 comprises a command receiving device 7, which is configured to receive an opening request command for the door 4 from the outside of the motor vehicle 1. Specifically, the device 7 comprise a member that be touched from the outside of the motor vehicle 1, for example a lever, which is well visible in figure 2. Alternatively, the touchable member could be a button or even a touch-sensitive surface, for example of the capacitive or inductive type or the like, or a heat-sensitive surface. The touchable member is preferably coupled to the body 2. Furthermore, the touchable member conveniently is separate from the door 4. Hence, in this case, the opening request command comes from the user U, who touches the device 7, as shown in figure 2. This is not limiting; as a matter of fact 7, the device could comprise an electromagnetic signal receiver. Therefore, the opening request command could be an electromagnetic signal, for example emitted by an electronic device, for example a remote control, a mobile phone and the like, according to a corresponding command of the user U. The motor vehicle 1 further comprises a control unit ECU coupled to the devices 5, 7. T
