How to auto rig a vehicle with multiple meshes for unreal engine 4.9 in maya 2014

I am new to UE4 jumping ship from Unity :smiley:

I have a vehicle with +200 mesh/polygons the problem I have is most tutorials are just showing a vehicle with a body and 4 wheels (1 root bone for the body and 4 bones for the wheels) . Now I need to know if I need to create a bone for each mesh/polygon which are +200 ? or is it possible to attach multiple polygons to a single bone or auto rig if its possible to auto rig all the mesh/polygons in maya ?.
