PURPOSE: A fuel consumption evaluation system and a vehicle driving evaluation system are provided to easily calculate the load factor of a vehicle engine and enable proper driving of the vehicle based on the engine factor. CONSTITUTION: A fuel consumption evaluation system comprises an RPM(Revolution Per Minute) detecting unit(56), an accelerator opening degree detecting unit(55), a fuel injection amount calculation unit(50), and a fuel efficiency evaluation unit(54). The RPM detecting unit measures the engine rpm of an engine-driven vehicle. The accelerator opening degree detecting unit detects the opening degree of an accelerator. The fuel injection amount calculation unit computes fuel injection amount per predetermined unit from the accelerator opening degree and the measured engine rpm based on the relation between the engine rpm drop calculated from the reference rpm and the variation of fuel injection amount. The fuel efficiency evaluation unit evaluates fuel efficiency based on the fuel injection amount calculated by the fuel injection amount calculation unit.
