A8:
Trans- changes shift program (holds gear longer, faster up/down shift)
MDS - off
Steering - user defined [comfort/normal/sport]
ESP - user defined [on/sport/off]
AES - matches increased throttle response
SRT Track mode has some differences unique to SRT models

Your neighbors got an A8, Sport Mode could result in decreased mileage because MDS (multi-displacement) will be deactivated. You'll be running all 8 cylinders full time. On an M6, I can't imagine it would affect mileage much if at all. Here's something he can do to see the difference: cruise at a constant speed and don't move your foot on the gas pedal...so don't give it any more or less gas...then hit the sport button. The car will pick up speed. So it doesn't give you any more power...they just change the threshold so in regular mode 50% of the gas pedal swing may give you 50% engine power. In sport mode 50% gas pedal might give you 60% engine power. Makes you feel like the car has more power but the total power pot is still only 485. So your to-the-floor power can't change.
Tell em sport mode don't make him any faster & to hold that L
