Ive never owned an Audi so o just have a few questions.Forgive my lack of knowledge

1.Are all models TFSI?
2.I have noticed in some models the little screen between the tachs is a multi color screen but the one I viewed was orange.Why is that?
3.Another difference I spotted was in other Audi’s the buttons controls were around the gear yet in this one the below the radio.Why exactly?


i hope this is the right board to post this in

thank you in advance
