A two-stage power-split gear unit for automobiles consists of an input shaft (2), of a planetary gear unit as an off-road gear stage, of a differential gear unit, of a first output shaft (13) and of a second output shaft (15) which is connected to an offset output (19), the input shaft (2) being capable of being coupled selectively to the sun wheel (5) and to the planet carrier (7) of the planetary gear unit, the planet wheels (8) of which roll in a ring gear (9) fixed in space, and the differential gear unit having compensating wheels (11) and first and second output wheels (14, 16) driven by these and in each case located on the first and the second output shafts (13, 15). In order to arrange the output wheel (16) for the front axle as far forward as possible and to save space, the compensating wheels (11) are mounted on the planet carrier (7) of the planetary gear unit of the off-road gear stage, and the first output wheel (14) is arranged in front of the planetary gear unit (5, 8, 9) of the off-road gear stage and the second output wheel (16) is arranged behind said planetary gear unit.
