A dual-clutch transmission of a countershaft design includes a main transmission and a downstream group transmission. The main transmission has a solid first transmission input shaft connected to the output of a first powershiftable clutch, a hollow second transmission input shaft connected to the output of a second powershiftable clutch/electric machine, through which the first transmission input shaft extends, and two countershafts arranged coaxially with one another. The first countershaft is a hollow shaft and the second countershaft passes through the first countershaft. A drive output shaft of the main transmission is arranged coaxially with the two transmission input shafts and is the drive input shaft of the group transmission. The drive input sides of the powershiftable clutches/machines are connected to a drive aggregate, and to bridge across the group transmission, the second countershaft can be connected via a shifting element to the group transmission drive output.
