Purpose of The System




The E65/E66 front suspension uses the double pivot spring strut axle design with tension rods (based on the E39 528i). The multi-link rear suspension with the integral axle is also used in the E65/E66 to allow each wheel to move and flex individually without transmitting loads and forces through the sub-frame to the other wheel.

The suspension is equipped with coil springs on the front and rear (standard equipment) providing the best comfort possible.This suspension systems keep the vehicle level during hard acceleration, braking and cornering.

One of the factors that influenced the E65/E66 suspension design was weight reduction. This results in improved fuel economy and handling characteristics (reduction of unsprung weight). The front and rear axle carriers, front and rear control arms, tension rods and front hub carrier assemblies are all made from aluminum. The weight is reduced by approximately 30% as compared to using steel components.
