The main features of the design are an aluminium-intensive frame structure consisting of profiles and nodes, functionally integrated shear surfaces as sandwich structures. Sills and side members are designed as aluminium profiles, which offer both length variability and adaptability in cross-section as well as further potential for functional integration. The transition from the floor module to the front/rear section is realised using node structures. The node structures offer a good opportunity to integrate as many functions as possible at these module interfaces and to create module interfaces for the various derivatives. Sandwich structures are used particularly in the area of the double floor and the battery box. The UMV Basic, Long and Peoplemover derivatives do not have a rigid B-pillar, which is integrated into the doors. The target weight of the UMV Basic body shell is 182 kg. The modular system is therefore designed in such a way that a large number of identical parts can be used to create very different derivatives at an attractive price.
