Sport Mode (Exhaust

My 2011 GLK 4MATIC does nothing more than change the shift points. This, in turn, can make the exhaust sound louder, but only due to the higher revs in each gear.

Sport mode also sharpens up throttle response, in addition to the higher gear shift RPMs and holding onto 6th gear for awhile longer than necessary IMO.
