Audi Belgium have a YouTube channel which has examples of most of the Driver Assist options:

Edit - URL didn't work, found this longer video which I think has most of the assist videos combined.

So how does the acc utilize full stop? With gradual slowdown with the car in front to a full stop? Emergency braking is just slowing 25 down. Thanks for sharing this knowledge. This is really Important to know what the car is really capable of. These details truly help.

I was driving on the interstate today using ACC when I ran into backed up traffic (must have been an accident ahead). The system brought the car to a complete stop without me applying the brakes. Although I must say, I was just about to put the brakes on, I was getting nervous it wouldn't stop. Anyway, if I wasn't testing the system I would have slowed down and put the brakes on well before the system did since I could see the stoppage coming up well ahead of time. Nonetheless, it was good to know, that it will stop the car.

Setting the ACC distance to the car in front and also ensuring ACC is in comfort mode can help make it less aggressive.

Had mine set to 3, the default. I can see setting it to 4 or 5 would have it engage sooner.

It would be extremely helpful, for me anyway, to experience all the driver assist features in a controlled test track type setting. I've used ACC Traffic Assist and that is no problem. What I'd be real interested is the pre sense especially the pedestrian avoidance.

Is it possible to locate such a test track? I live in Mass. Already called one of those "defensive" driving schools and have not heard back. Any thoughts?

There seems to be conflicting information on all the pre-sense language.

The question; is there a difference between pre-sense and pre-sense plus?

Presense is the general term for the systems. Presense rear (which can anticipate a rear end collision by rolling up the windows and tightening the seat belts) and presense front are components of presense "plus".

AND I had on the left turn signal, under the 6.2 MPH with NO oncoming traffic as the oncoming car had already passed behind me. Think we should consider requiring a little more than a "test drive" and require a USA car complete and through demo on just how it does work. I am writing a note to Consumer reports asking that they look into the different type of AEB provided by the different models. Audi was ambiguous, IMO, or their sales reps were .

We had the EXACT same thing happen to us. Making a left turn, after oncoming traffic passes, the car came to a sudden and abrupt stop in the intersection. Very fortunate we weren't rear ended. Consequently, we're now pretty uncomfortable with the auto-safety features as we just don't understand how or what they react to.

Worth checking.
