I tested this many times on the same route many times. You can feel more irregularities in the road much more when you had the sport button on. My wife could tell if I had it on without even looking to see if it was no. It has been 45+/- days since I have seen my 11 with AD(At the dealer for issues) and cannot remember if i could tell the difference when I had the sport button on but then again I have 20's now. If and when I get my car back I can update.
