VULCAN Compact 4x4 is a four-wheel independent chassis dynamometer designed for electric vehicle testing. By controlling each tire independently, the system supports the evaluation of four-wheel independent control, regenerative control and torque-vectoring technologies.

The system provides differential rotation and differential torque control between the front and rear and left and right sides. Torque at each axle can be measured separately, while low inertia per axle and fast acceleration support braking and tire-friction evaluations.

Its installation area is equivalent to that of a conventional chassis dynamometer. The compact design allows installation in existing facilities without modification or new construction, while in-house assembly and delivery help minimize downtime.
