E82 Complete Vehicle
Rear Axle "HA 5"
The rear axle on the E82 is of the development designation "HA 5" and was used for the
first time on the E90. Currently all E9X vehicles are equipped with a version of this rear
axle assembly.
It is designed as a multi-link independent rear suspension axle with 5 different link arms.
The designation "HA 5" does not refer to the five links but represents the consecutive
development designation used at BMW.
