Automatic transmissions modes.

What is the difference between Drive and Sport.
I dont really notice much. It only holds agression for longer, is that it?

I was hoping that there was a way for shifts to be quicker in S then in D

 

If I am not mistaken, it holds higher revs for longer & also lets the engine rev to higher RPMs. It also might make the throttle more responsive but haven't tested that myself

 

I just tested a bit ingame and it does apear the agression number tends to sit a bit higher and just stays higher all around.
