An amusement ride vehicle includes a vehicle chassis that rolls on caster wheels. Pinch drive wheels, driven by on-board electric motors, engage a guide rail and propel the vehicle along a rack. A motion base is positioned on top of the vehicle chassis. A yaw ring is rotatably supported on the motion base. A passenger cabin is mounted on to the yaw ring. A slip ring assembly extends from the vehicle chassis to the passenger cabin, to provide electrical power and audio signals to the passenger cabin. A yaw drive motor turns the yaw ring, allowing the passenger cabin to spin on the motion base, and to provide continuous yaw movement. The motion base provides pitch and roll movements, as well as heave, slip and surge movements.
