What suspension does the BMW M140i use?

[Willis]

BMW M140i uses an independent suspension system. The front suspension is a double-joint independent suspension, and the rear suspension is a multi-link independent suspension. Here is an introduction to the multi-link independent suspension: 1. Definition: The multi-link independent suspension consists of links, shock absorbers, and damping springs. It has more links than a typical suspension. By convention, suspensions with 4 or more links are referred to as multi-link suspensions. 2. Function: The multi-link suspension not only ensures a certain level of comfort but also, due to the increased number of links, allows the wheels to maintain as vertical a position as possible relative to the ground, minimizing body tilt. This maximizes tire contact with the road surface.

I've driven the BMW M140i several times and particularly admire its suspension system. The front suspension is a MacPherson strut independent suspension, while the rear is a multi-link independent suspension, which is quite common in sports models. The MacPherson setup is simple and lightweight, allowing for more precise steering and strong support during cornering, giving a feeling of flying close to the ground. The multi-link rear suspension optimizes handling balance, providing superb stability at high speeds, especially on winding mountain roads where the body barely tilts. Of course, this doesn't mean it's stiff—comfort mode still absorbs shocks on bumpy roads, making daily commutes smooth. I think this suspension design perfectly complements its powerful B58 engine, with overall tuning leaning toward sportiness, making every drive feel like an exhilarating track experience. For long-distance driving, it might feel a bit firm, but for me, that small sacrifice is worth the pure driving pleasure it delivers.

As a young owner who just got my hands on the M140i, I have to say its suspension design is truly practical. The front wheels use MacPherson independent suspension, while the rear features a multi-link independent setup—this combination makes city driving exceptionally smooth. During daily commutes, the suspension absorbs most vibrations when encountering potholes, keeping the ride comfortable inside the cabin. On weekend getaways, whether taking corners or accelerating, it remains stable with excellent handling. Maintenance isn’t complicated either—I regularly check the shock absorbers to prevent wear from prolonged rough rides. However, the suspension has a sportier tune, so you’ll feel its firmness over speed bumps at high speeds, but it’s manageable once you get used to it. Overall, this system strikes a great balance between comfort and performance, making it perfect for someone like me who enjoys spirited driving without too much hassle.

With over 20 years of car repair experience, I find the BMW M140i's front MacPherson strut and rear multi-link suspension quite reliable. These structures are common in sports cars and offer strong durability – the shock absorbers have a long lifespan, only prone to damage under aggressive driving or harsh road conditions. I recommend owners inspect the rubber bushings every 20,000 kilometers and replace them if cracks appear to prevent abnormal noises. Maintenance is straightforward; just pay attention to cleaning accumulated dust around the wheel hubs during regular car washes. This suspension setup is tuned for firmness and precise handling, but it produces noticeable noise on bumpy roads, which new drivers may need time to adapt to.
