The invention relates to a side wall group (1) for a passenger vehicle, comprising a B-pillar (2) made of fiber-reinforced plastic, at least one additional pillar (3, 4) made of fiber-reinforced plastic and situated after the B-pillar in the rear direction, and a side wall (6) which is made of fiber-reinforced plastic and defines a segment of the outer skin of the passenger vehicle. According to the invention, to make it possible for a side wall group of this kind to offer high stiffness for absorbing operating and crash loads while being low-weight, to have a high surface quality, and to be economical to produce with short production times, the B-pillar (2) comprises a hollow pillar (2.1) made of metal as a core element.
