The kit system (14) according to any one of the preceding claims, wherein the mechanical connection interface (33) of the support structure (15) corresponds to a mechanical connection interface (33) for a predetermined body type of the motor vehicle (10) in that the connection interface (33) in particular comprises a respective connection element for at least one engine bearing and/or for at least one engine bearing strut and/or for at least one hydromount.

The kit system (14) according to any one of the preceding claims, wherein at least one adapter (27) of at least one adapter type for mechanically and/or electrically adapting at least one of the equipping components (16) to a respective predetermined existing component of the motor vehicle (10) is respectively provided.

The kit system (14) according to any one of the preceding claims, wherein the support structure (15) is completely or partially configured as a grid frame (50) with at least one grid rod.

The kit system (14) according to any one of the preceding claims, wherein an energy storage unit is provided for an installation space of a fuel tank and/or a trunk of the motor vehicle (10), which comprises installation places for battery modules (25), wherein an electrical connection device is provided, which each provides an electrical connection to the electric traction drive (40) both with full equipment and with partial equipment of the installation places of the energy storage unit with battery modules (25).

The kit system (14) according to any one of the preceding claims, wherein a predetermined, spatial orientation of a rotational axis (55) of a rotor of the electrical machine (18) is preset in the support structure (15) by an equipment place for an electrical machine (18) of the electric traction drive (40) and the support structure (15) comprises at least one support element (54), which protrudes from the support structure (15) transversely or obliquely to this spatial orientation of the rotational axis (55), to in particular rest and/or abut in the engine compartment (12) as a torque support.

A support structure (15) for a kit system (14) according to any one of the preceding claims, wherein the support structure (15) comprises a mechanical connection interface (33) for fastening the support structure (15) in an engine compartment (12) of a motor vehicle (10) of a predetermined body type and equipment places (28) for fastening each one equipping component (16) in and/or on the support structure (15), wherein the respective equipment place for the respective equipping component (16), for which the respective fastening place is intended, is each shaped for abutting and/or for locking the equipping component (16) and/or comprises a fastening device for fastening the equipping component (16).
