I drove a non-S F56 with manual transmission the other day and was positively shocked at how seamless the rev-matching function was upon downshifts. Each downshift was achieved perfectly. This was the first time I had driven a vehicle with automatic rev-matching.
To disable it, apparently you have to fully disable the stability control.
I'm not sure if I liked losing that control to the superior algorithms. :|
What do you all think of the rev-match?
