My 2015 R's parcel shelf is the same as my 2013 GTD's was. Can't see any reason to have any variants except perhaps colour (light grey vs anthracite etc.) to match different interiors in the range. The dimensions of the boot is the same in all cases for the hatch, even the R (only difference being the R's boot floor can't be put in the lower position that the GTI/GTD can).
