A power wheelchair includes a frame, a powertrain including a motor, gearbox, and powertrain suspension coupled to a drive wheel. The powertrain suspension includes a powertrain mount connected to the motor. The mount is pivotally connected to and resiliently supported by an upper link and a lower link for movement of the drive wheel relative to the frame. The power wheelchair further includes a base suspension connected between the frame and the caster support arms. The base suspension is dynamically controllable to vary caster suspension movements in response to sensor outputs to reduce pitching motions.
