A system for indicating the miles to go for use in a motor vehicle the indication being generated in response to signals representing the fuel consumption and the fuel remaining in the vehicle, the system including a transducer for sensing the speed of the vehicle, for example in miles per hour, and a circuit for conditioning that signal to provide an output analog signal indicative of the speed of the vehicle, the output of which is fed to an analog divider circuit. The system, in the case of a fuel injected engine, also includes a circuit for sensing the fuel injection pulses, to provide an additional input to the analog divider circuit. The miles per hour signal is divided by the fuel consumption gallons per unit time circuit to provide an output signal indicative of the miles per gallon fuel consumption of the engine at the sensed operating condition. This signal is multiplied by a gallons to go signal which may be derived from the fuel remaining indicator system of the vehicle. This multiplication provides a miles to go indication which may be fed to the operator.
