For the first time I used the D Mode as I have been driving in the N Mode since I got the car last month. It seems as if the transmission shifts differently; it was little bit faster not by much. However I didn't feel much difference in the steering. I'm starting to wonder if there is something really wrong with this car. I drove a TI loaner from 12/16 build it felt like a better made car and it was way faster than my car.
