One youtube review that I remember was saying that the engine calibration is a bit different. Golf R feels a bit more eager to be revved. But I didn't drive any of them so I'm in the dark.
I test driven the Focus RS and the ride (we have really bad roads in Romania) is unbearable. Beside the sh*tty interior.
I want a good all arounder: nice interior, good dynamics, winter drivebility, low taxes (in Romania running a 2L costs 50e/year in local taxes, running a 3L and you go up ten times to 500e/year). So RWD with 3L is not really for me.
