Tyres make the difference. The new Euro ratings help with choice although need to be careful as the same tread on different wheel sizes make a difference to noise levels. My MKVI is on Bridgestone and can't wait for them to wear out! Very noisy. The Scirocco is on P7 self seal and is remarkably quiet in comparison. Wet handling with P7s is not quite as good but the handling is better than the Golf in any case and they last very well.
