GolfR is awesome.
New one will be on the new sportier chassis.
135i is awesome too but I'm willing to bet on a average British day in average British roads with the average driver a golf R will be quicker than a 135i on the twisties.
That's down to driver confidence, rather than the car's ability.
VAG are very good at making safe feeling cars that flatter the driver, so anyone can get in one and instantly give it Billy big balls and go tentenths.
Thats good and hilarious fun, but what are you learning?
I'm about 90% confident in my car, it still has the ability to scare me and get the adrenalin going, but it really rewards if you're prepared to stay committed. Having driven a stock Golf R, I know I'd be significantly faster in a 135i in anything but rain. It has 50:50 weight distribution and is unaffected by torque steer. Haldex is clever, but not Subaru/Evo clever, its trump card seems to be 0-60 straight line launches and exiting wet roundabouts, otherwise it's just dead weight being dragged about.
Drag time pub bingo and going fast in the rain is not on my list of wants when buying a new car.
There seems to be a perception that RWD has no grip, in the dry it has way more than FWD and HaldexAWD. In the wet yeah sure, it'll be overwhelmed by power, but then so is FWD - the only difference is the enevitible entering of that hedge being forwards or backwards.
VAGs are great cars, I've had a few and really enjoyed them, I dare say I may have another at some point - but you can't beat RWD and that's why I've gone back to it.
