I have noticed this as an option only on the new A8s. I would like to know more about it, but can't find much info. Is there any aftermarket type device being offered and will Audi start offering it on the other models?

For the driving I do, I would find it a very useful feature. I am just wondering if I can somehow get a system for my current car as the A8 I really want is a bit away into my future.

I know of no way adaptive cruse control can be intergated in a after market setting.
I have it on my A8L and it is an excellent aid. Good luck

I figured, especially being a $2K option. When did they introduce this feature? I take that it is fairly new.

I'll just have to wait till I have some spare change for that W12.
