1. A modular motor vehicle architecture for motor vehicles of different motor vehicle types with, in each case, at least one drive unit and at least one energy store assigned to the at least one drive unit, comprising:
a modular designed underfloor energy store assembly that has a plurality of energy store modules which are standardized in terms of at least one external dimension, the at least one energy store being received in the underfloor energy store assembly, wherein
each motor vehicle type is assigned one underfloor energy store assembly from a plurality of standardized underfloor energy store assemblies, and
each underfloor energy store assembly has a plurality of uniform module installation spaces which are standardized in terms of a longitudinal dimension which runs in a longitudinal direction of the motor vehicle, and which are configured to receive, in each case, at least one standardized energy store module;
wherein the underfloor energy store assembly has a further uniform module installation space region with at least one shortened uniform module installation space, the longitudinal dimension, running in the longitudinal direction of the motor vehicle, of the further uniform module installation space region and the longitudinal dimension, running in the longitudinal direction of the motor vehicle, of the shortened uniform module installation space being shorter than those of a regular standardized uniform module installation space region and a regular standardized uniform module installation space, respectively.
