Guaranteed that all North American passenger cars will consume the most fuel and travel the least distance at full throttle.
Highway cruising is the most efficient, 55 down to 40 mph will give you the best mileage.
Very high RPM consumes very much fuel, the two are joined at the hip.

If you have a fixed maximum speed (the speed limit) and you spend very little time in the high consumption mode of heavy throttle, then settle into the low consumption-per-distance full cruising speed for the longest duration per interval (between stops), that should use less fuel overall than accelerating for a very long period of time and cruising for a shorter time.
