An electric drive configuration for a skid steered vehicle comprises: a pair of propulsion motors ( 74 a, 74 b), each with a motor shaft protruding from both ends of the motor and mounted on the same axis across the vehicle, each being coupled at the outer end to drive one of a pair of tracks or set of wheels of the skid steered vehicle; a control differential steep gear unit ( 72 ) positioned between the two propulsion motors and in driveable communication with the inner ends of the two motor shafts: and a steer motor ( 71 ) in driveable communication with the controlled differential ( 72 ), the steer motor ( 71 ) being controllable from zero speed giving straight line running in which both motor shafts are coupled to run at the same speed, to a range of speeds in both directions of rotation giving steering capability in both directions.
