Abstract: A self-supporting underframe for a vehicle, the vehicle, and a production method thereof. The underframe has two elongate monocoques arranged parallel and spaced apart from each other and at least 50% closed on at least four sides, wherein the monocoques each have a single-part, trough-like element having at least one lower base and two side walls extending upwards from the base. At least one cover element closes the trough-like elements over at least 50% of the longitudinal extent of the particular trough-like element. The at least one cover element of each of the two monocoques in each case includes at least one cross-strut cover element, and the cross-strut cover elements of the two monocoques are designed as a common, single-part cross-strut cover element spanning an intermediate space located between the trough-like elements of the monocoques. The cover elements are fixedly connected to the side walls of the monocoques.
