The problem with the present GTI is, it is piggy in the middle between the frugal and relatively fast GTD and the performance orientated and superior R.
Now, when the R400/420 emerges and when the present piggy in the middle GTI is superseded by the GTI Clubsport, there will be no piggy in the middle. However, the GTI Clubsport still won't be as fast as an R.
Both GTIs might probably remain exclusive by default.
Interestingly, the bottom positioning of the GTD, for performance Golfs, is secure.
