Last weekend, I went to a Tesla test drive event and drove a new Model S 100D (likely Dec 2017 production). The one difference I noticed when compared to my 2016 90D (post-refresh) is that the steering seemed to offer more feedback from the road, and it also had a considerably more pronounced return-to-center feel. I was driving in Sport mode. The demo car was running all-season 19-inch tires.
