A system and method for maximizing a vehicle's fuel efficiency preferably without inconveniencing the driver, includes maximizing a ratio of a real-time parameter proportional to engine load or engine power to fuel flow or air flow rate referred to herein as the P/F ratio. This ratio is calculated to evaluate engine fuel efficiency. With the system and method, the throttle is operated incrementally to increase or decrease the throttle in a manner to maximize the P/F ratio, thus maximizing fuel efficiency, in a pulse phase. The system and method implement an on and off pulse width modulation (“PWM”) style of control to modulate engine power and acceleration to achieve the speed that the driver desires, based on the position of the accelerator pedal. When the desired speed is achieved, the throttle is released and when the speed drops a sufficient amount, the throttle is re-engaged to reach the desired speed again. When the throttle is disengaged or when the driver releases the accelerator pedal, the system and method implement a glide phase, where the vehicle coasts without use of fuel or in neutral with very limited use of fuel and minimum engine drag.
