Mitsubishi cars with the 4G64 engines have the fuel monitor. It is part of the MMCS (Sat Nav + entertainment functions). The Fuel monitor show one the litres in the tank and the distance one can travel with that fuel based on the average km/litre calculation which is done ever 1 minute. When in a jam the inefficiency shows eg 6km/litre .. when on a nice long stretch highway doing about 110km/h the consumption is much more efficient at 16km/litre or something
