Disclosed is an underbody structure (10) for a motor vehicle, comprising a floor (14) and at least two longitudinal side rails (12) arranged on either side of the floor (14), respectively; the floor comprising a raised portion (16) under which a propulsion battery pack (17) is intended to be mounted; the underbody structure further comprising at least one cross-member (22) arranged above the floor (14) and attached to the side rails (12) by its ends. At least one cross-member comprises a rigid zone extending transversely over at least the width of the raised portion (16) of the floor; and zones at each end of the cross-member that are capable of compressive deformation in the event of an impact, each compression-deformable zone comprising means for promoting the gradual compressive deformation thereof. The underbody structure provides increased protection for the battery and the passengers of a vehicle.
