Advantages:-
1) traction is nearly double compare to two wheel drive layout.
2) give sufficient power this result in on parallel acceleration and drivability on surface with less than ideal group and superior engine braking on loose surfaces.

Disadvantages:-
1) the manufacturing cost of the vehicle is high.
2 more components and complicate transmission.
