What does really the Sport Button do? When I push it I can feel the car shake a fraction of a sec, but what exactly happens? I imagine the suspension becomes stiffer, gas pedal response might be better, although I don't see why it wouldn't be fast even with normal mode on. But what else?
I know this could be a really stupid question, but as a 10 day new owner of 4.8 xDrive with all possible packages, I'm curious to know what to expect and do I really have.
Thanks all!
