What is independent rear suspension?

Independent rear suspension (IRS) is a type of rear suspension system in vehicles that allows each wheel to move independently of the other. This means that the movement of one wheel does not affect the movement of the other, providing a smoother and more comfortable ride for passengers.

IRS is typically used in higher-end or performance vehicles, as it offers improved handling and overall driving dynamics compared to solid rear axle suspension systems. It also helps to reduce body roll during cornering and provides better traction, especially when driving on uneven or bumpy surfaces.

There are a few different types of independent rear suspension systems, including double wishbone, multi-link, and MacPherson strut setups. Each system has its own advantages and disadvantages, but they all work to provide a more refined and better-performing ride quality compared to solid rear axle suspension systems.
