Abstract: A powertrain testing apparatus for testing performance testing of a powertrain provided with an input shaft and an output shaft that are disposed on different axes. The testing apparatus includes an input motor that replicates rotation of a vehicle-drive engine, an output motor that replicates the load applied to the output shaft in actual service, an input side support having an input connection shaft for connection to the input shaft, an output side support having an output connection shaft for connection to the output shaft, and a vibration generator that replicates vibration transmitted from a road surface in actual service. Vertical and horizontal adjustment units enable inter-shaft distances D1 and D2 between the input connection shaft and the output connection shaft to be changed. Constant velocity joints respectively connect the input motor and the input connection shaft and the output motor and the output connection shaft, thus enabling eccentric positioning thereof.
