The invention relates to a vehicle body structure in the floor region of the occupant compartment having on both sides a respective longitudinal beam () in the floor region of the occupant compartment between a transmission tunnel and a side sill. According to the invention each longitudinal beam () extends longitudinally continuously over the entire footwell length from the front end () to a heel plate. The longitudinal beam () is here formed on the bottom side as a closed longitudinal hollow beam by virtue of a longitudinal beam stepped edge () of the floor panel (AB) and on the top side as a longitudinal beam closure part (SW) by virtue of a longitudinal beam angle section connected to the top side.

The invention relates to a vehicle body structure in the region of the A-pillar and the windshield cross member, including an A-pillar on both sides of the body, wherein in the pillar construction of the A-pillar, the A-pillar has an A-pillar inner steel plate oriented approximately vertically and in the vehicle longitudinal direction. An approximately horizontal windshield cross member is connected at the ends thereof to the associated A-pillar inner steel plate by means of a welded connection. According to the invention, the windshield cross member is produced as a composite component made of an elongated aluminum beam having steel plate adapter parts that extend the aluminum beam at the ends thereof but are short in comparison to the overall beam length, and the steel plate adapter parts are connected to the associated A-pillar inner steel plate by means of the welded connection and to the aluminum beam by means of a riveted connection.
