The present disclosure relates to a method performed by a user interface system (12) of a vehicle (10) for providing a graphic visualization (302) of a propulsion energy level gauge (304) relative to a vehicle range meter (306). The user interface system determines a current vehicle range of the vehicle based on a current remaining propulsion energy level of an energy storage device of the vehicle, and determines at least one hypothetical vehicle range of the vehicle based on at least one hypothetical level of remaining propulsion energy of the energy storage device. Additionally, the user interface system provides the graphic visualization on a display (14), where the propulsion energy level gauge conveys the current remaining propulsion energy level and the hypothetical level of remaining propulsion energy, and the vehicle range meter conveys the current vehicle range and the hypothetical vehicle range. In the graphic visualization, the current remaining propulsion energy level is graphically associated with the current vehicle range, and the hypothetical level of remaining propulsion energy is graphically associated with the hypothetical vehicle range. Accordingly, a e.g. driver of the vehicle may glance at the presented hypothetical vehicle range for consideration of a presumably desirable timing of refueling/recharging, without confusing said hypothetical vehicle range with the current vehicle range. The disclosure also relates to a user interface system in accordance with the foregoing, as well as a vehicle comprising such a user interface.
