What type of strut is less complicated and commonly used in unibody vehicles?

The MacPherson strut is often considered the simplest type of strut suspension system and is widely utilized in unibody vehicle designs. This design features a single strut that combines a shock absorber and a spring into one assembly, allowing for a more compact configuration. This simplicity reduces the number of components and makes for easier assembly, which is advantageous in mass production settings.

Additionally, because unibody vehicles typically prioritize weight efficiency and space constraints, the MacPherson strut's configuration fits well within these requirements. It allows for a lighter and less complex suspension system, enhancing handling and ride quality while also providing sufficient support and stability for the vehicle's body structure.

In contrast, other types such as the double wishbone strut, rigid strut, or independent strut systems generally involve more components and complexity, which can impact the manufacturing costs and space efficiency. Thus, the MacPherson strut’s design is ideally suited for the needs of modern unibody vehicles.
