I note when you look at the 19's on the configurator it says "Progressive steering" which it doesn't on the 18's.

Reading around this seems like it is genuinely something different with a Audi derived steering rack. I wonder how much of the "feel" reviewers have talked about might be down to this.... all of the press cars have 19's and DCC....
And then you have to choose between "Dynamic Chassis Control (DCC) variable suspension settings, sport comfort and normal - for 19" alloys" or "Sport Suspension for 19" wheels"
Which means there isn't a choice of 18 rated suspension with 19's....
The lack of explanation of these things and the pros and cons is crazy. I know the Mk7 was the same but this is nuts.
