A hybrid drive unit includes a transmission having an input shaft and first and second countershafts. An internal combustion engine is directly couplable to the input shaft via a clutch. There are seven shiftable gear pairings, each including a gearwheel arranged coaxially to the input shaft. The first gear pairing has a first gearwheel formed as an idler gear and arranged coaxially to the input shaft, and a second gearwheel formed as an idler gear and arranged coaxially to the first countershaft. The electric machine is connected to the first gear pairing such that torques are transmittable from the electric machine to the transmission via the first gear pairing. Viewed in an axial direction, the first shiftable gear pairing, a first shifting element plane, the second shiftable gear pairing, the third shiftable gear pairing, the fifth shiftable gear pairing, a second shifting element plane, the sixth shiftable gear pairing, and the seventh shiftable gear pairing are arranged one behind the other in that order. The third and the fourth shiftable gear pairings are arranged on the same axial gear plane.
