Yes, it will, but it is not the regular "Hill Assist". I was speaking to a program manager about it at the Premier and he was a little reluctant to go into details - evidently they are still holding back some of the cars features for some reason. Anyway, it will hold the car from rolling backwards and forwards on an incline for sure. I'm not clear on what else it does but I was told they have incorporated it into a new type of hold feature specifically for the i3.
