Abstract

A motor vehicle rear (10) has left and right longitudinal members (12) forming a supporting structure of the motor vehicle. A receiving housing (18) is arranged between the longitudinal members (12) for receiving a traction battery. The receiving housing (18) has a left and right side walls (22, 24) running in the forward direction of travel. A back wall (20) is connected to the left and right side walls (22) and running transverse to the forward direction of travel. An impact profile (26) is connected to the left and right longitudinal members (12, 14) and absorbs impact energy in the event of a rear crash. Left and right reinforcing elements (32 34) connect the impact profile (26) to the respective left and right side walls (22, 24) for reinforcing the impact profile (26) and conducting away some of the impact energy into the left and right side walls (22, 24).
