A new generation of the acc is used in the 
Audi A6 Avant `05. This acc incorporates the 
following modifications:

the exterior dimensions and weight of the acc unit 
(sender and control unit) were substantially 
reduced.

adaptive cruise control (acc)

The number of radar transceivers integrated into the sender was increased from three to four. 
As a result, it was possible to increase the beam angle from 8 degrees to 16 degrees. By increasing the range 
of the sensor, objects in the path of the vehicle can be detected earlier. The maximum range of the object 
detector was increased to 180 metres from 150 metres. The acc functionality was significantly improved with 
regard to lane-changing and winding country roads.
