1. A powershift transmission of a motor vehicle having a motorized drive, the powershift transmission comprising:
a split group with a plurality of powershift stages, an input shaft, and an output shaft, the input shaft configured to be rotatably driven by a drive shaft of the motorized drive, wherein the split group transmits rotational movement in a stepped-up manner to the output shaft of the split group, the rotational movement corresponding to one of the plurality of powershift stages;
a synchromesh transmission group having a plurality of gear stages, an input shaft, and an output shaft;
an intermediate group having an output shaft and an input shaft, the intermediate group positioned between the synchromesh transmission group and the split group, wherein the synchromesh transmission group is configured to be rotatably driven in a stepped up manner by the output shaft of the intermediate group, the output shaft of the intermediate group is parallel to the input shaft of the intermediate group;
an axle transmission configured to be rotatably driven by the output shaft of the synchromesh transmission group; and
wherein the intermediate group has a multiple powershift intermediate transmission, and in each switching position, the input shaft of the synchromesh transmission group can be rotatably driven by an associated transmission of the multiple powershift intermediate transmission.
