The invention relates to a hybrid drivetrain comprising a combustion powertrain and comprising an electrical powertrain, both for the needs-based provision of torque to an output element, wherein thecombustion powertrain has at least an internal combustion engine, a generator, a variable transmission, and a torque clutch for connecting and disconnecting a torque transmission from the internal combustion engine to the output element, and wherein the electrical powertrain has at least one electric machine, and wherein the hybrid drivetrain also has 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 hybrid drivetrain is primarily characterised in that the reduction gearing hasa direct combustor input stage and a direct electrical input stage, the variable transmission is offset in parallel to and/or axially overlaps the internal combustion engine, and/or only a single-stage fixed-speed torque-transmission drive is provided as an axial extension of the drive shaft. With the proposed hybrid drivetrain, a very compact architecture is created which can be flexibly adaptedto any installation space requirements.
