In this article I am going to discuss the advantages and disadvantages of air suspensions systems. But before I begin, I would like to briefly explain what an air suspension actually is.
What is an Air Suspension System?
Air suspension is a type of vehicle suspension that is powered by an electric or engine-driven air pump or compressor. In an air suspension system, the steel springs or leaf springs are replaced with an air spring. Air springs comprise of a rubber membranes that hold pressurized air. This pressurized air is what the car rides on.
The Advantages of an Air Suspension System:
Air suspension system is sometimes called “air ride”. Air suspension has many different benefits which may be useful to drivers interested in luxury cars. The main advantage of an air suspension system is the improved ride quality it offers. Cars with air suspension are often said to “glide” over bumps, when compared to steel spring suspensions (which cause a harder ride). Air suspensions are often adjustable, as the electric or engine driven air compressors can be controlled.
The biggest advantage of an air suspension is that SUVs with this feature have an increased towing capability. In most SUVs, the driver can increase firmness when towing. This makes it easier to overcome the heavy load. In cars with the traditional suspension (spring suspension), large loads can weigh down the vehicle.
The Disadvantages of an Air Suspension Systems:
There are two major disadvantages of this system and both are related to the cost. First of all, the air spring suspension is mostly an optional feature in a car. Only luxury cars like the Mercedes S-class and Range Rover etc. include this feature as a standard. In short, it is a quite expensive feature.
Secondly, if you purchase a used car with this system, the cost of repairing it and maintaining it is expensive. Air suspension is great when it’s working fine, but is quite expensive to fix if it spoils. Many used car owners with this system often replace the damaged air suspension with the regular spring suspension.
Well, should you go for the air suspension or not? It’s recommended to take the car for a test drive, with and without the feature. This way you can decide if it is really worth the extra bucks. If you are buying a used car with the air suspension, get the suspension inspected by a mechanic or get in touch with PakWheels CarSure to examine the car’s condition.
