A transmission arrangement (100) for an electric vehicle. The transmission arrangement comprises a differential (102) configured to connect a first electric machine (104) to a first and second wheel via a respective first and second driveshaft (106, 108). The transmission further comprises a coupled epicyclic gear (110) configured to connect a second electric machine (112) to the first drive shaft via the coupled epicyclic gear. The transmission arrangement comprises a coupled epicyclic gear using a single planet gear (120) which meshes with two sun gears (116, 118) of different size, which can be compared to instead using a stepped planet gear comprising two planet gear portions of different size.
