Imagine a car that constantly adjusts its suspension in response to changing road conditions in order to ensure a continuously smooth ride. It gives you a firm/sporty ride, without being jarring and crash over bumps/rough roads. As this happens, the metal particles within the fluid are aligned, greatly increasing its thickness (viscosity) and effectively stiffening the suspension to reduce body roll. This inherently involved a compromise, as cars designed to be luxurious offered a soft ride at the expense of good handling, and vice versa., The idea behind adaptive suspension is to eliminate any trade-offs between ride and handling by allowing the customer to choose the settings that best suit their driving environment.
