Summary:The invention relates to a chassis of a motor vehicle optimised for absorbing a frontal impact. Said chassis (1) of a motor vehicle includes a firewall separating the passenger compartment of the vehicle from a front portion (1a) of the chassis intended for holding the engine, and a means for absorbing a frontal impact comprising two side rails (3) mounted on at least the front portion (1a) of the chassis (1) and arranged on either side of the chassis (1), each side rail (3) including a front portion (3a) and a rear portion (3b) assembled such as to overlap at least partially. The side rails (3) are arranged such that the overlap area is below the plane of the firewall, and the rear portion (3b) of the side rail includes a material which is less compressible than the front portion (3a) of the side rail.
