A chassis for a four-wheel drive vehicle is presented. The vehicle chassis has a front sub-chassis assembly, rear front sub-chassis assembly, front hinge assembly, rear hinge assembly, main chassis frame, an independent powertrain sub-assembly for each wheel and electronic control system. The sub-chassis assembly can rotate about the axis of the hinge assembly. Each powertrain sub-assembly is controlled by the electronic control system. With torque vectoring control of the electronic control system, various combinations of driving and braking torque of each wheel can be achieved. The front sub-chassis assembly and the rear sub-chassis assembly can therefore rotate in clockwise or counter clockwise, which make the vehicle steer or translate even without conventional steering mechanisms.
