1. A rear axle drive for a motor vehicle having a Cardan shaft, comprising:
a pinion shaft having a pinion,
a hollow shaft having bevel gear toothing and spur gear toothing,
a differential having a differential spur gear firmly attached to a casing of the differential, and
a connecting shaft that is led through the hollow shaft, the connecting shaft comprising a connecting shaft spur gear which is different from the differential spur gear and part of an electronic torque vectoring transmission gearing, wherein the rear axle drive is configured such that rotation of the connecting shaft is transmitted to the differential by way of the electronic torque vectoring transmission gearing,
wherein the pinion shaft is connected to the Cardan shaft of the motor vehicle and the pinion of the pinion shaft engages with the bevel gear toothing of the hollow shaft and the spur gear toothing of the hollow shaft engages with toothing of the differential spur gear of the differential.
