1. Automotive vehicle engine fuel consumption measuring device, in which the vehicle has a multi-gear range transmission (17) comprising, in accordance with the invention, the combination ofa pressure sensing means (35) sensing pressure in the induction pipe of the engine and providing an engine pressure signal;

  • an indicator (36) having a plurality of scales (42, 43,

         44) which provide fuel consumption indications, each scale being specific to a specific gear range of the vehicle transmission, said indicator responding to the pressure signal so that the indication output of the pressure sensing means will indicate, directly, fuel consumption per unit distance (miles per gallon;

    kilometers per liter;

    liters per 100 km) in which the vehicle then operates; and

    optical means (52, 53,

         54) coupled to the vehicle transmission (17) and optically indicating the respective one of the scale which is associated with, and representative of, fuel consumption of the vehicle engine at the then engaged gear range.
