1. A system for providing an endurance mode for an electric vehicle, comprising:
a demand controller configured for determining a demand made by a driver to provide electrical power from a battery of the vehicle to an electric motor configured to propel the vehicle;
a mode selector operable between at least an endurance mode and a qualify mode depending on a mode input received from the driver;
a battery controller configured for determining a supply of electrical power available from the battery to meet the demand; and
a supply controller configured for controlling use of the supply according to the mode input, the qualify mode permitting a maximum amount of the supply to be available for use in meeting the demand, the endurance mode permitting a limited amount of the supply to be available for use in meeting the demand, the limited amount being less than the maximum amount; and the supply controller is additionally configured for controlling use of the supply according to the endurance mode unless an accelerator pedal position is at a full displacement position while the mode input is set to the qualify mode, the accelerator pedal position configured to represent the demand made by the driver.
