1. A method for producing at least two design variants of a motor vehicle having a housing element for a storage housing of a storage device, the storage device being configured for storing electrical energy and having a plurality of storage cells arrangeable in a receiving space of the storage housing and in which the electrical energy is stored, the method comprising:
providing a first reinforcing element, in the form of a first perforated plate, which is exclusive to motor vehicle design variants;
providing a second reinforcing element, in the form of a second perforated plate, which is different from the first reinforcing element, and is exclusive to different motor vehicle design variants; and
providing at least one basic element which is universal across motor vehicle design variants and from which a housing part, which is universal across motor vehicle design variants and at least partially delimits the receiving space, is produced, wherein:
(i) either the housing part is reinforced by the first reinforcing element, as a result of which a first motor vehicle design variant is produced, or the housing part is reinforced by the second reinforcing element, as a result of which a second motor vehicle design variant is produced;
(ii) the respective reinforcing element intrinsically has a plurality of through openings extending through the perforated plate which are spaced apart from one another and are separated from one another, the plurality of through openings forming a respective pattern of perforations of the respective reinforcing element;
(iii) the reinforcing elements differ from one another in their pattern of perforations and/or in their shape of the respective through openings; and,
(iv) the housing part is connected to a self-supporting body of a motor vehicle such that a main floor of the motor vehicle at least partially delimits the receiving space.
