A hybrid drivetrain includes an output element, a combustion powertrain, an electrical powertrain, and a torque-transmitting, fixed-speed reduction gearing connected to the output element for reducing a speed of the internal combustion engine and the electric machine. The combustion powertrain has an internal combustion engine with a drive shaft for delivering a first torque, a generator with a generator shaft for converting the first torque into electrical energy, a variable transmission arranged to variably transmit the first torque, and a torque clutch for connecting and disconnecting transmission of the first torque between the internal combustion engine and the output element. The electrical powertrain has an electric machine with a rotor shaft for delivering a second torque. In an example embodiment, the torque-transmitting, fixed-speed reduction gearing has a direct combustion input stage for the combustion powertrain and a direct electrical input stage for the electrical powertrain.
