That autocar article is jut a cut and shut of a million other articles.
No more door has been an on and off thing for ages now. Last I heard yes to 3 door, but not to convertibles.
All of the other bits in that article you could guess pretty much by looking across the VAG range. It is highly unlikely that anything in the Mk8 Golf will not have been seen before in an Audi or other VW car that's recently been revamped.
So lets just play lego with those bits and say "it could have" and insert some of those features.
Of course, it won't get all of them, but I'll say again, there will be nothing you haven't been able to see before here.
The only real guessing game is quite how much it looks like a Passat vs a Vauxhall Astra.
