A transmission arrangement for a hybrid vehicle includes a powershift transmission, a summing gear assembly, a first transmission input shaft, and a second transmission input shaft. The summing gear assembly is for transmitting a drive torque to a drive shaft. The first transmission input shaft is connectable to an electric machine to transmit a first drive torque from the electric machine directly to the summing gear assembly. The second transmission input shaft is connectable to an internal combustion engine to transmit a second drive torque from the internal combustion engine to the summing gear assembly via the powershift transmission.
