Abstract
A system and method for determining and displaying an overall efficiency value of a vehicle. The vehicle may include an engine and an electric machine that operates to provide torque to propel the vehicle. In addition, the vehicle may have an electric power source that provides electric power to the electric machine. A controller may determine and transmit the overall efficiency value so that the information display displays the number of efficiency indicators. Also, the number of efficiency indicators displayed may be based on the overall efficiency value.
