Which is better, multi-link or torsion beam suspension?
3 Answers
Multi-link independent suspension is better than torsion beam semi-independent suspension. The differences between multi-link independent suspension and torsion beam semi-independent suspension are as follows: Different suspension methods: Multi-link suspension is an independent suspension, while torsion beam suspension is a non-independent suspension. In an independent suspension, each wheel is individually suspended under the frame or body through an elastic suspension system. In a non-independent suspension, the body and tires are not directly connected. Different composition methods: Multi-link independent suspension consists of links, shock absorbers, and damping springs. This type of suspension uses more links than conventional suspensions. A four-link or five-link suspension is referred to as a multi-link independent suspension. Different stability levels: Because this type of suspension uses more links, it can keep the wheels as perpendicular to the ground as possible, minimizing body roll to the greatest extent. During driving, it helps maintain good stability of the vehicle.
As a driver who frequently uses family cars, I believe the choice of suspension depends on daily usage. The multi-link suspension in my family car makes a noticeable difference when taking trips with the family: less vibration over speed bumps and rough roads, the kids don't get as jostled in the back seats, and overall comfort is higher. However, the torsion beam version is cheaper and more durable. I've driven a friend's compact car with this setup—simple structure, easy maintenance, and perfectly adequate for city commuting. If you're on a tight budget, the torsion beam is a great choice; if you prioritize long-distance comfort, it's worth spending a bit more. When buying a car, consider road conditions—multi-link is better for bumpy rural roads, while torsion beam is more economical for smooth city roads. Additionally, multi-link systems have more complex components, making repairs expensive if something breaks. Torsion beams are easier and cheaper to maintain, saving money and hassle, which suits someone like me who prefers simplicity.
From a driving experience perspective, having driven many cars, I believe good handling is paramount. Multi-link suspensions provide much more stability when cornering, giving a strong sense of tire grip on winding roads, with precise and crisp handling. Torsion beams, on the other hand, are weaker in this aspect, as their lateral movement is limited, making them prone to wobbling during quick lane changes. However, torsion beams aren't without merit—they're simpler in structure and lighter, which improves fuel efficiency in budget models. My recommendation is to choose based on the car type: multi-link is better for sporty cars, while torsion beams are sufficient for economical daily drivers. Don’t forget maintenance costs—multi-link suspensions have more parts and are prone to issues, while torsion beams are rugged and rarely need repairs. This difference becomes clear after long-term driving.
