The climate and seat warmer/cooler controls are capacitive touchscreen, I think...but most of the controls for infotainment are physical. The overall UI/UX for the car is pretty sweet...save form some odd quirks (for some reason my phone will occasionally reboot when android auto is being used; sometimes if I drive the car after my wife, the seat tries to kill me), it's been pretty good.
What is very clever is that the star button can be custom-mapped. I have it set up for "Passenger talk". It lowers the radio and turns on an in-car intercom so I don't have to yell for my kids to hear me.
