how to make car like "hill climb racing" in unity 2d?

I’m prototyping game like a “hill climb racing” in unity2d. The car must have physics like car in “Hill Climb Racing”. I’m not able add physics to my car. I want to add suspension to car, right now my car looks static.
Any kind of help would be appreciated.
