A power transmission apparatus for a vehicle having an engine and a motor/generator includes: a first input shaft selectively connected with a motor/generator; second and third input shafts disposed coaxially with the first input shaft, and selectively connected with the motor/generator; a torque mediating shaft disposed coaxially with the second input shaft; an intermediate shaft in parallel with the first input shaft; an idle shaft in parallel with the first input shaft, and selectively connected with a transmission housing; a first shifting section including four gear sets, receiving torque through the first and second input shafts, and providing intermediate shift-stages; and a second shifting section including a planetary gear set, forming an output torque by combination of torques from the first shifting section and the third input shaft, and outputting the output torque to the output shaft.
