Comparation w/DCC vs without/DCC

[Twiki]

It is known the influence of the DCC system in the car suspension.
However, I have found information that relates the impact of the system not only in the steering (also noticeable) but also in the car acceleration and braking. Even in a communication scheme between different car modules, I found that ACC (Cruise Control) is somehow linked to the operation of the DCC.

Apparently, in Sport mode, throttle response is quicker and the braking more abrupt.

Testing the two limit positions (Sport and Comfort) we clearly note major differences in the behavior from the suspension and the steering. In the case of engine or braking, I don`t know if it is a fact or just psychological.

The truth is that the DCC system communicates with the module ABS / ESP and also with the engine module. How he does, I don't know.
Is there a remapping?

Does anyone know a comparison between a car with DCC (in Sport mode) or without DCC in terms of acceleration or braking?

Is the behavior of a car without DCC equal to a car with DCC in normal mode?

The description of the DCC system is in the attached link. It appears that the various modes - comfort, normal and sport work within their own separate 'windows' so are not constant but adaptive to road surface conditions within those windows. The only time this does not happen is if the system fails and goes into 'safe' mode. The shock absorbers then act like conventional shock absorbers. Therefore normal mode cannot be compared to cars without DCC.

The steering is sharper in sport mode as the modules communicate with each other via the canbus. The canbus also connects to the ABS system and accelerator position in the diagrams in the link description but it is not totally clear if their performance is modified by suspension mode although I think it probably is and that is why they are included.

I saw the same description in a site named my-GTi:

And from and official VW site I found this:

"Adaptive chassis control (DCC) makes it possible to adjust the running gear to a normal, sporty or comfortable tuning. The electrically adjustable damping system adapts automatically to the setting, as does the electromechanical power steering.
DCC responds continually to changing driving situations and takes braking, steering and accelerating operations into account.
Adaptive chassis control (DCC) provides for considerably enhanced driving characteristics. The driver is no longer restricted to a certain running gear configuration. Rather, he is able to individually adapt his vehicle. A push of a button on the centre console is all it takes."

As you said, probably also braking and acceleration is changed but that is unfortunatly not clearly said.
