My simple answer would be by all means staying with your Model S.
As to why, well, I don't know if I really need to tell these things on a Tesla forum but anyway, if you need to be told, then you would be delivered. That turbocharged engine will burn a load of gas. I know because I own an Audi of same injection type. If you park in a closed garage, it will smell and it WILL be disgusting. Getting a Tesla is what I want the most right now (however, my current budget doesn't let me to, but that's not the topic), so I'm not sure why anybody would be in the mind of ditching a Tesla for ANY Audi. There are other issues like the transmission used in it that leads to various issues, but I'm not going to get into those and just leave at this.
