Abstract
A vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, and a rechargeable power source can be configured for reduced fuel consumption at idle. The vehicle drive system includes an electric motor in direct or indirect mechanical communication with the first prime mover. The control system causes fuel to be eliminated to the first prime mover while the vehicle is stopped and causes the electric motor to rotate the first prime mover at a speed, thereby reducing fuel consumption at idle for the vehicle.
