The invention relates to a hybrid powertrain in a motor vehicle with an internal combustion engine (1), an electric machine (2), a variable transmission (4) and one or more driven wheels (3). The transmission (4) includes at least a variator unit (9) for varying the output speed of the internal combustion engine (1) and a first differential gearing (5) with three rotary members (51, 54, 53) that are respectively drivingly connected to an output shaft (92) of the variator unit (9), a rotor shaft (21) of the electric machine (2) and a wheel shaft (31) of the driven wheels (3). The invention concerns a method for operating such a hybrid powertrain.
