I have a 2020 S3 (in the US). I've heard that there are differences between the all-wheel drive on the S3 and the S4. I've found nothing about this in web searches. San you help?
S3/S4

The S3 AWD is similar to VW Golf system. The S4 is all Audi. I'm not sure how it comes out on the road, I guess most drivers wouldn't notice the difference. Before is was that the Golf AWD was Haldex-based, which meant the car was actually front-wheel driven most of the time, and the rear joined in when the wheel spin was detected. The A4/S4 system was AWD all the time. It seems this might not be the case anymore, since the S3 tehcnical data also says the all-wheel-drive system is constant.
Thanks, JKP. Any more specific/technical information is welcomed as well. It's odd to me that there isn't more discussion of details like this on a forum like this. 
I guess I'm used to motorcycle forums, but it seems the Audi crowd is more mature and doesn't have as much time for such dalliances.
