basically its the engine that does all the work even though indirectly..the engine transmits power to the wheels through the drive line...now its the wheels that exerts force on the road and reaction force acts on the wheel and since the wheel is connected to the car, the whole system moves...

suppose engine is exerting force on the car...engine is also a part of the car...then by newton's 3rd law..car(excluding engine) will also exert force on the engine..just take an analogydw:1347165086979:dw

this car(in the above figure) is without any engine..and magnet is hanging in front of the car..will the car move or accelerate?

suppose engine is exerting force on the car...engine is also a part of the car...then by newton's 3rd law..car(excluding engine) will also exert force on the engine...then net force on the car(with engine) is zero!!!dw:1347165421811:dw
