Multi-link is known as the best and most practical
independent suspension . As independent suspension, multi-link wide used and
applied by car manufactured for rear suspension. Why it is called multi-link ?
By looking at the design of multi-link suspension, there are about three or
more lateral arms and one or more longitudinal arm. Thus, multi – link
suspension also called multi - arm suspension.

Multi link can have 3- link but it also can have as
much as 5-link. It is all depend on the theory and practical uses of the car’s
demand.

Since the late 80s, multi link suspension has been
popular choice when its come to rear suspension. Among the earlier car that
applied multi-link suspension are Nissan 200SX, Infiniti Q45, Mercedes S-Class
and BMW 3-Series.
Different approach has been applied when using multi
link suspension. Thus, different derivative giving different geometry and
different characteristic. An example, BMW multilink system giving Z shape.
Thus, it is called Z-Axle. In addition, Audi A4 ‘s Quadralink front suspension
has 4 link . Its look alike double wishbone but eliminate torque steer.
For now, the development of multi – link suspension
still under gradual progress by research company. In example, an Italian
company majored in auto electronics component, Magneti Marelli under
significant time to produce cost-effective multi-link system for small cars. In
its design it induce flexible link.
