Just looked myself. It does show the word Macan. You can either go back to the dealer with pics lined up to show him... or pay for the word and put it on yourself. I would not think they're that expensive any longer. Model's been out snce '15.
Yes, and all that I have seen so far, have Macan. Tried looking online at tailgates and all have one form of Macan with S or GTS or just Macan, none without it. Was wondering if it had been wrecked and they just didn't put it back on when fixing, but no sign of any painting repairs.
I am guessing that who ever built this car choose to have the model designation deleted. I am sure if you would like your model on the back, your dealer will be more than happy to add it for you with probably a nice cost.
