On demand wheel drives

Extra pulling power and mobility when needed

How is it possible for a light vehicle to haul a heavy trailer without a loss of vehicle combination's performance?

The answer is the Black Bruin wheel drive motors. A light vehicle can act as a tractor if the trailer wheels also are driven.

Black Bruin puts its high torque just where it is needed – under the cargo! An extra pulling power is generated when needed and motors can also be used as a main transmission.
