the vehicle in the video is a rear wheel drive, you can see it from the burnout while facing the wall, but you can apply torque to anny of the wheels you want, even apply torque to the left wheels only if you want to xD it is very customizable, and the vehicle body does not have to be a skeletal mesh at all, it can be, but does not HAVE to. I just made a collision mesh inside 3ds max, using the UCX thing. Any mesh you use with the default wheeled vehicle class should work with this class too.
