Incorporating various significant improvements and refinements, the rear axle of the new BMW 3-Series makes an important contribution to the new model's improved driving dynamics and comfort. Its space-saving design is based on the tried-and-tested five-link design used on the predecessor model, with elastokinematics which have been specially tailored to the new sports sedan, featuring long spring travel and precise and confident wheel location in all situations.

Extra-wide mounts and supports on the wheel carriers for track and camber, extremely stiff control arms, the stiff axle subframe and thrust arms connecting the suspension and body provide an excellent basis for the agile and, at the same time, comfortable overall suspension qualities of the new BMW 3-Series Sedan. The large mounts and supports at the rear axle not only affect handling, they are also important for ensuring good acoustic insulation between the powertrain and suspension, particularly on vehicles with a powerful, high-torque engine. Thanks to the effective insulation of the powertrain from road excitations, the new rear axle therefore also provides first-class noise and vibration damping.

The classic BMW 3-Series rear-wheel-drive set-up and a balanced weight distribution also provide the ideal basis for resolving the conflict between ride and handling. As a result, the new BMW 3-Series impresses with extremely sporty handling combined with highest standards of stability and comfort. Last but not least, the reduced-friction wheel bearings, robust powertrain isolation and carefully targeted aerodynamics modifications at the rear axle also contribute to improved driving dynamics and efficiency.
