Every modern automobile has a suspension, and engineers are usually forced to choose between firm springs and dampers that maximize grip, or soft ones that increase ride comfort at the expense of traction. Mercedes-Benz, however, came up with a system called Active Body Control that automatically adjusted suspension response to keep the car level and comfortable at all times. It was introduced as standard on the CL-Class, S600, and S55 AMG, and as an option on the S430 and S500.
“Conventional suspension systems rely on substantial body movements to move oil through dampers and compress the springs. The power of ABC comes from its ability to detect the slightest steering wheel and body movements on entry to a corner and to anticipate what corrections will need to be made at each wheel before any large body motions occur. It works amazingly well.” – KC
