The invention discloses an automobile body torsion box and an automobile. The automobile body torsion box comprises a threshold inner plate, a front longitudinal beam rear section outer sealing plateand a front auxiliary frame rear mounting plate assembly which are connected in sequence; the automobile body torsion box further comprises a front torsion box main plate assembly and a front surrounding plate lower cross beam assembly; one end of the front torsion box main plate assembly is connected with the threshold inner plate; the other end of the front torsion box main plate assembly is connected with the front longitudinal beam rear section outer sealing plate and the front auxiliary frame rear mounting plate assembly; the front surrounding plate lower cross beam assembly is connectedwith the front torsion box main plate assembly and the front auxiliary frame rear mounting plate assembly; four first independent cavities are formed between the front longitudinal beam rear section outer sealing plate and the front torsion box main plate assembly; two second independent cavities are formed between the front auxiliary frame rear mounting plate assembly and the front surrounding plate lower cross beam assembly; and the front longitudinal beam rear section outer sealing plate, the front torsion box main plate assembly and the threshold inner plate form a triangular structure. With the automobile body torsion box and the automobile adopted, the problems of low strength and poor direct impact force and side impact force transmission effect in the prior art can be solved.
