  • Patent number: 5383683
    Abstract: The present invention is concerned with a motor vehicle, in particular, a motor vehicle having an electric motor, comprising a chassis having at least three wheels, with the side walls of the bottom part of the chassis containing the seats being formed of cross-connected hollow elements and the upper part of the chassis being formed as a hatch to be opened at least partly. To essentially reduce the front-sided in-flow drag, in the practice of the invention, the hollow elements are formed of two tubular supports open at the front and rear ends. All cross-sections of the supports, between the openings of identical cross-section, correspond to the cross-sections of the openings. The cumulative cross-sections of the two supports correspond at least to half the cross-sectional size of the bottom part of the chassis.
