Method and system for starting an internal combustion engine of a hybrid vehicle, where the internal combustion engine is adapted to rotate a drive shaft providing torque to at least one driving wheel of the hybrid vehicle via a transmission unit; where the transmission unit comprises a first clutch connecting the internal combustion engine to an input shaft of a gearbox connected to a torque converter, where the torque converter is connected to a second clutch connecting the torque converter to the at least one driving wheel through a transmission, where the input shaft is connected to an electric machine; the method comprising the steps of; disengaging the second clutch to a predetermined torque level such that there is a slip in the second clutch; engaging the lock-up clutch; engaging the first clutch to bring the internal combustion engine to a first rotational speed; disengaging the first clutch when the internal combustion engine has reached the first rotational speed; starting the internal combustion engine by injecting fuel and igniting the fuel, and engaging the first clutch when the internal combustion engine has started and rotates with a second rotational speed.
