In a double-wishbone suspension, two triangulated wishbone-shaped arms and a track rod guide the wheel. The suspension strut is attached to the lower wishbone and provides the necessary vertical support. The characteristics of this suspension design include a low installed height and a generous through-loading width, enabling the adoption of wheel suspensions that favour a sporty overall set-up. This has a beneficial effect on 4MOTION drive, the transmission of high active forces and road holding. The double-wishbone suspension takes up little room and, with an appropriate track rod layout, prevents severe load alteration effects. Further variants include the extremely compact trailing-link double-wishbone suspension and the trapezoidal-link rear suspension.
