Things can be left as they for me. A GTi doesn't need 300bhp. That's for the enthusiasts, not the typical GTi driver that has no intention of ever taking it anywhere near a track.
I'd bet the majority of GTi buyers don't visit forums such as this one, and most won't know exactly how fast it is to 60mph. They'll have bought/leased it simply because it's a GTi and that's something with heritage and a reputation. It makes no commercial sense to remove the GTi as one of VW's most renowned cars from the mainstream market and aim it at enthusiasts instead. 🤷♂️
