Tried out "Sport Mode" today (a small risk with only 200 miles on the clock) and the car went hyper! Quite impressive differences to the throttle response, gearshift program (on the DSG), steering feel and suspension (as I have ACC).
Interestingly the "soundaktor" (or what ever it's called) made it throatier, but gruffer. Not unpleasant under load but I quite like the natural thrum of the engine ....
