A body for a motor vehicle includes a side member, which is made from a fiber-reinforced plastic composite, and a deformation element. The deformation element is designed such that it can absorb collision energy in a low relative speed range of the motor vehicle through fracture. The side member is designed such that it can absorb collision energy in a high relative speed range of the motor vehicle through brittle fracture. A side member start-of-fracture force level, at which the side member first starts to fracture, is greater than a side member mean fracture force level, at which the side member goes on to fracture. A deformation element start-of-fracture force level, at which the deformation element first starts to fracture, and a deformation element mean fracture force level, at which the deformation element goes on to fracture, are lower than the side member start-of-fracture force level. The deformation element mean fracture force level is lower than the side member start-of-fracture force level and greater than a force level corresponding to a side member mean fracture force level reduced by 10%, preferably 5%.
