The front axles of the current BMW 5 and BMW 7 series can be considered as further developed traditional strut-type suspension, see figure.
→Substitution of the lower wishbone by two struts.
→Formation of a virtual point of intersection of the steering axis to the plane of the lower wishbone, which on the one hand causes a minor steering offset, which increases with the steering angle, as well as the disturbing force lever arm, and on the other hand permits a larger brake disk to be installed due to a minor wheel offset.
→Front-axle bracket is an aluminum weld assembly and hence a weight reduction of 5.4 kg is achieved.
