AWD variant not available in high end??

Suspension is nice in this model. Can any one tell about the suspension and off road performance of AWD variant? And why renault down graded Awd variant into RXS model. Previously it is available in RXZ now it is in RXs missing somany features. Some of them Cruise Rear wiper & washer Foglamps Electrical ORVM. I hope renault will upgrade AWD variant to RXz.
