The suspension for the A8 (type 4N) has been redesigned, with new technologies and control systems to achieve even greater levels of comfort, dynamics and safety. All of the available suspension options include air suspension with electronic damping control. The front and rear axles each consist of a responsive, high-precision five-link construction made in large part out of aluminium.

Progressive steering, included in the standard vehicle equipment, reduces the amount of steering effort required. Optional dynamic steering, offered by Audi here for the first time, combines dynamic steering with rear wheel steering. This system enhances certain essential subjective and objective dynamic characteristics of the driving experience.

The generously proportioned brake system offers substantial performance reserves for any driving situation.  A ceramic brake system is available as optional equipment. The 9th generation ESC system provides high-performance stability control for the vehicle.
A wide range of steering wheels, wheels and tyres is available for further customisation. With the Audi A8 (type 4N), ACC is included for the first time in the new driver assist system “adaptive cruise assist”. For further information, please refer to self-study programme 668.

Audi A8 (type 4N) vehicles are equipped exclusively with running gear versions with quattro four-wheel drive. The following running gear versions are available:

  • Running gear with air suspension and damping control (adaptive air suspension, 1BK)
    This running gear version is part of the standard equipment.
  • Running gear with air suspension and damping control (adaptive air suspension sport, 2MA). This running gear version is available as optional equipment. The suspension and damping are regulated for a more dynamic driving experience.
