Early 518 models are equipped with carburetors, but on all other models systems of injection of fuel are installed. Transmissions are established either five-step manual, or three - or four-stage automatic. Transmission is located on a back part of the engine, and power is transferred to completely independent back bridge via the driveshaft, two-piece. The block of the main transfer is reliably attached by bolts to a cross beam of a frame and sets in motion back wheels by means of the power shafts equipped with the internal and external hinges of equal angular speeds (HEAS).
Forward suspension bracket - rack-mount, like McPherson, with the block of a twisted spring / shock-absorber making connection of the top part of a suspension bracket. The back suspension bracket consists of type racks a twisted spring on the shock-absorber or of a twisted spring and the ordinary shock-absorber, depending on model.
