Four-link suspension

The four-link suspension is different from other types of designs due to the independent operation of the control and suspension elements. Using four-link front suspension, the structure of the car is indirectly supported by the strut mounted on the support arm. The wheel is guided by four rod-shaped wishbones and a track rod. This structural principle improves steering behaviour and minimises the effects of road bumps on steering.

For the rear axle, four-link suspension can be designed very compactly. This allows for longer displacement that is compatible with all-wheel drive. Moreover, the four-link rear suspension works as a lane-corrector in the border area.

In SEAT models, the multi-link rear axle (or multi-link rear suspension) is used as a design according to the four-link principle. It features 3 transverse arms and 1 trailing arm per wheel.
