A motor-vehicle with driving and steering rear wheels comprises a rear suspension system that includes a support frame (2) for the rear suspension, mounted on the body of the motor-vehicle. For each rear wheel (R), a wheel support (K) is provided which is connected to the support frame (2) by means of a plurality of oscillating arms (7, 8), which are articulated to the wheel support (K) through joints that define a steering axis (S) of the rear wheel (R). An actuator (A) is mounted on the support frame (2), with two control rods (12), protruding from opposite ends of the actuator body (A), and connected to the wheel supports (K) by means of two control articulated arms (B) controlling the wheel supports. Within the space between the two rear wheels (R) there is a rear motor (M) of the motor-vehicle, or a rear differential unit of the motor-vehicle. The body of the actuator (A) is mounted on the support frame (2) along a transverse direction which is spaced apart from the axis (13) of the rear wheels (R) of the motor-vehicle to an extent sufficient to avoid interference with the motor (M) or the differential unit that occupies the space between the rear wheels of the motor-vehicle. The two articulated control arms (B) controlling the wheel supports (K) are substantially parallel to a transverse direction perpendicular to the longitudinal direction of the motor-vehicle, or anyhow form an angle therewith not exceeding 15 degrees. The control rods (12) protruding from the body of the actuator (A) are each connected to the articulated control arm (B) controlling the respective wheel support (K) with the interposition of a transmission.
