MagneRide on the S550 Mustang is an adaptive suspension. The magnetic ride replaces the traditional dampers found on passenger cars with monotube dampers that are filled with magnetorheological fluid.
Magnetorheological fluid, or MR fluid, is known as a smart fluid in that its properties can be controlled by applying electric current to it. Electromagnetic coils in the dampers apply the current according to conditions which are measured by various electronic sensors.
The fluid in the dampers travels faster or slower depending on the amount of current applied to the coils. Less resistance gives a better ride quality. As driver input or road conditions change, the resistance of the fluid is rapidly adjusted which can stiffen or loosen the ride.
There are no moving parts in the MagneRide dampers. With no moving parts, there is nothing to wear out. The MR fluid allows the shock absorbers to adjust almost instantly — 300 times faster than the blink of an eye according to the manufacturer.
After reading how a traditional damper works, you can begin to understand how this will improve the Mustang’s handling capabilities in all conditions making it sharper and safer.
