adaptive air suspension58
Dynamics and comfort were once opposites.
We’ve made the differences vanish into thin air.
Fully load-bearing air springs
on the front and rear axles of the
vehicle to provide a sporty and
comfortable driving feel.
*Please consult your Audi partner or national Audi website to find out more about the special features of the ceramic brake.
The fuel consumption and CO₂ emission figures can be found from page 120 onwards.
Every road is different - but there’s no reason for
you to notice. How do we do it? In the Audi A6 and
A6 Avant the optional adaptive air suspension
adapts the suspension for many different driving
situations and for the road. An electronically
controlled air suspension system operates
individually on each of the 4 wheels and is
combined with an infinitely variable adaptive
damping system. Sensors on the body and on the
axles monitor the current driving situation and
send information to the system during the journey.
The air springs also guarantee that, even when
carrying heavy loads, the vehicle’s driving
characteristics will hardly be impaired.
In the Audi A6 allroad quattro the standard
adaptive air suspension automatically regulates
the vehicle height and damping. The optional
Audi drive select allows you to choose between
5 pre-sets (dynamic, auto, comfort, allroad, lift)
which raise the A6 allroad quattro up to 18.5 cm
above the ground – a full 5 centimetres more
than is available in the A6 Avant.
In the Audi S6 and S6 Avant the new adaptive air
suspension sport with S6-specific setting is used
as a standard. The more tightly configured air
suspension with variable damper coordination
sets the trim of the body lower. The adaptive air
suspension sport is controlled by Audi drive
select and is designed to be very agile without
compromising comfort in the process. The
standard high-performance brake system in the
S6 and S6 Avant features strong, all-round
ventilated disc brakes and takes a powerful hold.
The brake discs comprise a cast friction ring
which is connected to the brake disc chamber by
means of steel pins. This so-called floating
mounting ensures that the friction ring remains
tension-free to a major extent, improving
stability under extreme temperature loads. For
tougher requirements, a 19-inch ceramic brake*
is available on request in the S6 and S6 Avant and
for specific engine models of the Audi A6. In this
brake system, the brake discs are made of a
carbon-fibre reinforced ceramic material. This is
based on hard and abrasion-proof silicon carbide.
This combination results in an enormous abrasion
resistance which allows extremely high mileages
to be achieved and at the same time reduces
sensitivity to high thermal loads.
