One of the major inefficiencies of a typical gasoline engine is the need to maintain a constant air to fuel ratio requiring a restriction of the air intake via butterfly valve at positions other than wide open throttle. I am not aware of any modern automotive gasoline engines that are functioning properly and have not been messed with by "tuners" that are wasting a significant portion of the fuel by not combusting it.
