Intresting question for you guys here,

I usually drive it in D or Manual mode, only have really used sport sometimes thru twisties and right before i pass someone slap it in s and foot to floor.

Now ive tried it driving around today etc, keeping it in S.

The most obvious things are the agressive shift points, touchier pedal and downshifts,

Ive also read it changes up the steering a little as we have active steering (at least i know the 4.8 does,

But driving around i was messingb around by putting it in S for a few sec then D, and it feels like the suspension dampening stiffen up as well,
I did some searches but came up with nothing, i did this on a long strech of road with imperfections and it really felt smoothed out in D, and tightend up in S.

I know my buddies e70 has the sport button for suspension and it stiffens dampening, but i swear i noticed it on mine as well i just want to see if it actually does or its in the head.

I do feel the steering input change as well as all the orher trans/pedal etc i said above.
