Adaptive suspension is a useful feature offered on many new vehicles. These systems allow drivers to adjust their suspension for specific conditions, and often include settings like Eco, Comfort, and Sport. So simply pushing a button can greatly impact how the vehicle performs.
Availability of these systems was once reserved for luxury brands. But today, they've become increasingly available on more affordable models. While exactly what&#;s included within the "adaptive" definition varies among brands, the adjustability typically covers traits like how well the car soaks up bumps, and how athletically it corners.

What Are the Benefits of an Adaptive Suspension?
In short, an adaptive suspension eliminates the inevitable compromises of a one-size-fits-all setup. This allows carmakers to fine tune a vehicle&#;s ride in ways once unimaginable. Now, a driver can tailor the firmness of the suspension as needed, perhaps softening the ride for passenger comfort, or stiffening it for improved cornering.
In a Comfort setting, for example, the suspension is more compliant, making it better at absorbing potholes. On the opposite end, Sport steps up the suspension&#;s control of wheel movement, and communicates more feel to the driver. These adjustments can improve roadholding by keeping the tires in better contact with the road surface, which is essential for sporty driving.

What Vehicles Offer Adaptive Suspension?
Adaptive suspensions are marketed under various names, including BMW Adaptive M Suspension, Lexus Adaptive Variable Suspension, and Mercedes-Benz Adaptive Damping System. A technology called MagneRide, developed by General Motors in the early s, was first introduced by Cadillac before migrating to the Chevrolet Corvette. Later, even the Ford Mustang and some Ferrari models would utilize MagneRide.

How Does Adaptive Suspension Work?
A number of mechanisms are used by adaptive suspensions to achieve their desired performance. Some systems, like ZF&#;s Continuous Damping Control, use electronically adjustable valves within the suspension dampers, and control movement by the internal flow of oil. When the valves are mostly closed, oil movement between chambers is restricted, and the suspension is firm and direct. When the valves open wider, the suspension is softer, and the damping effect is reduced.
MagneRide uses electromagnetic coils acting on a special damper fluid that contains tiny metallic particles. Varying the magnetic field shifts the alignment of the particles in the magnetorheological fluid, changing its flow characteristics to soften or firm up the suspension action.
Some sophisticated adaptive suspensions can also adjust to road conditions automatically, and make changes in a fraction of a second. To achieve this, sensors monitor a variety of factors, including the movement of each wheel, and alter the stiffness as you drive. Rolls-Royce even has a feature &#; called Flagbearer &#; that uses cameras to scan the road ahead, and prepare the suspension for bumps before the wheels ever encounter them.

The predictive active suspension is a fully active, electromechanically operated suspension system. It can increase or reduce the load on each wheel individually to adjust to the road as needed. The system therefore actively controls the position of the body in every driving situation.
For each wheel there is one electric motor supplied by the 48-volt primary electrical system. The electronic chassis platform (ECP) sends control signals to the active suspension every five milliseconds. One power electronics unit per axle processes them for the electric motors. A belt drive and compact strain wave gearing step up the torque of the electric motor to 1,100 Nm (811.3 lb-ft) and transfer it to a steel rotary tube. The tube houses and is rigidly joined to a pre-tensioned titanium roll bar. This bar is more than 40 centimeters (15.7 in) long, roughly 22 millimeters (0.9 in) thick and, despite its high strength, can be twisted more than 20 degrees. The force is transferred from the end of the roll bar to the suspension via a lever and a coupling rod. This force is exerted at the front axle on the pneumatic strut of the adaptive air suspension and at the rear axle, on the transverse link.
The range of ride characteristics takes on a whole new dimension thanks to the flexibility of the active suspension. If the driver chooses &#;dynamic&#; mode in the Audi drive select system, the car becomes a sports car. It turns firmly into corners and body roll angles are reduced by half compared with a conventional suspension. The body hardly dives at all during braking. In &#;comfort&#; mode, however, it glides smoothly over any and all road surface irregularities. The active suspension settles the superstructure by continuously adding energy to or removing energy from the body depending on the respective driving situation. This significantly reduces the system&#;s energy consumption. Its average power consumption is between 10 and 200 watts.
In combination with the Audi pre sense 360˚ safety system, the active suspension also enhances passive safety. The system uses the sensors networked in the central driver assistance controller (zFAS) to detect risks of a collision around the car. In the event of an imminent side impact at more than 25 km/h (15.5 mph), the suspension actuators raise the body on the exposed side by up to 80 millimeters (3.1 in) within half a second. As a result, the collision is directed to the even stronger areas of the vehicle, such as side sills and floor structure. The load on occupants is reduced by up to 50 percent compared with a side impact where the body is not raised.
