A method for manufacturing a central underbody portion of a structural body of a motor vehicle to delimit a bottom of a passenger compartment of the vehicle. The method includes assembling a floor of the central underbody portion, attaching an integral central profile to the floor, arranged in a longitudinal direction of the vehicle and having a length dependent on a length of the central underbody portion in the longitudinal direction, and assembling at least one end piece forming an extension of the central profile. The end piece has an interface providing a connection and a function of absorbing and transmitting forces with a structural portion of the body that is separate from the central underbody portion and/or with the floor. The attaching includes adapting the length of the central profile as a function of the length of the central underbody portion in the longitudinal direction.
