A look at Audi A8's predictive active suspension

By CARSIFU | 25 July 2019

INGOLSTADT: The Audi A8 luxury sedan now gets predictive active suspension which can provide a first-class travel experience, ranging from the supreme ride comfort of a chauffeur-driven limousine or the firm handling of a sports car.

In Germany and other European markets, predictive active suspension can initially be ordered for the TFSI versions of the Audi A8.

Predictive active suspension in the Audi A8 has electromechanical actuators that adjust the suspension.

The active suspension can lift or lower the body by up to 85 millimeters (3.3 in) from its central position at all four corners within five-tenths of a second.

In conjunction with the air suspension and Audi drive select dynamic handling system (both standard), predictive active suspension in the Audi A8 enables an unprecedented spectrum for driving.

In the “dynamic” profile, the luxury sedan acquires the handling of a sports car.

The A8 turns in firmly, and when cornering fast with 1 g lateral acceleration the body inclination (roll angle) is just 2 degrees – as opposed to more than 5 degrees with standard suspension.

If, on the other hand, the “comfort plus” profile is selected in Audi drive select, the luxury sedan glides with velvety smoothness over any bumps in the surface.

The predictive active suspension works together with the front camera.

Thanks to this camera, the flagship model identifies uneven surfaces before they are reached and predictively regulates the active suspension.

Even before the car hits a bump, the predictive function developed in-house at Audi signals the correct positioning travel to the actuators and actively adjusts the suspension.
