Top gear tonight:
Stig in Mk7 GTI . Circuit times with ACC in Sport, Normal and Comfort modes: 1m 29.6s, 1m 29.6s and 1m 29.5s respectively. Their words: 'Sport mode is the 'slow' mode' and very uncomfortable.
I suppose there is much to be said for a properly calibrated passive set-up.
For me, 'comfort' mode will always be my preferred choice on our poxy tarmac.
