Some embodiments are directed to a drive configuration for a skid-steered vehicle that has a pair of traction motors for rotationally driving opposite outputs of the drive configuration. The traction motors are operatively connected to the outputs via respective gearing arrangements for selectively varying gear reduction between each of the traction motors and the corresponding output. The drive configuration also has a steer differential in a torque connection with the first and second outputs of the drive configuration. The drive configuration additional has a steer motor operatively connected to the steer differential for selectively varying the rotational speed of the first and second outputs in use. Also, the traction and steer motors define a volume in which the gearing arrangements and steering differential are at least partially located.
