1. A power distribution architecture for an off-road vehicle, the power distribution architecture comprising:
a work circuit including a plurality of motion control units configured to be fluidly connected to separate hydraulic actuators, the motion control units each including an electric motor/generator mechanically coupled to a pump/motor;
an electrical bus for providing electrical power to each of the electric motors/generators;
a common pressure rail for providing hydraulic power to each of the motion control units; and
a prime mover which directs power through a power take-off to a mechanical transmission for driving propulsion of the vehicle, wherein the prime mover also is coupled to a mechanical power take-off to a pump for pressurizing the common pressure rail.
