A vehicle includes a powertrain having a battery-powered electric machine. The vehicle also includes a controller programmed to display, on a geographical map, at least one contour line indicating an available driving distance from a current location. The distance of the contour line from the current location is based on energy stored within the battery and predicted energy consumption due to driving along each of a plurality of possible routes originating from the current location. The predicted energy consumption is updated based on energy depletion events that occur during driving.
