PROBLEM TO BE SOLVED: To measure a rotational frequency and a torque, and to simulate a flow characteristic of an automobile and sound concentration action of the automobile in a wind tunnel, vibration analysis, noise generation, and material stress in an extreme condition relative to the automobile equipped with conventional wheels, by improving a device having a drive axle and one or more electric machines equipped with a rotor and a stator, in which a rotor axle of the electric machine is mechanically coupled with the drive axle and the drive axle is mechanically coupled with a driven axle for wheels through a releasable coupling part, relative to a device for measuring the rotational frequency and the torque of the driven axle for the wheels and simulating the running state. SOLUTION: The drive axle 4 is enclosed by a stator ring 8 concentric to the drive axle in a well-known form, and the stator 6 is fixed to the stator ring 8 in a well-known form, and the circumferential surface of this device 1 has a roughly rotationally symmetric automobile wheel shape, and the device is imbedded in a wheel housing 9 of the automobile A.
