Definition: Whereas the fuel consumption display (FCD) gauge expresses average fuel usage over a distance, this gauge presents a vehicle's fuel consumption instantly, as it is used. As the vehicle moves along, sensors continuously detect fuel flow rate, throttle position, engine speed and manifold pressure. Meanwhile, the onboard computer calculates results and displays them as miles per gallon or kilometers per liter, in real time, to the driver.
