    Abstract: A chassis for an automobile has inner and outer frames pivotally connected together intermediate front and rear ends of the frames. The inner frame is connected directly to a rear end without resilient suspension and supports a motor driving a differential and rear wheels in the rear end. The outer frame supports a car body and a driver seat. Front steering wheels are supported by respective resilient suspensions on the outer frame. Rear resilient suspensions include rocker arms and Watts links connecting the inner and outer frames spaced from the intermediate pivot for resiliently controlling pivotal motion of the outer frame relative to the inner frame. The rear suspensions are positioned in front of the pivot between inner and outer chassis frames and in front of the motor.
