Personally what I have experienced from driving the same vehicle with different engines (Grand Cherokee V6 vs Hemi V8) is little to no fuel economy. The reason being that with less power comes the need to press the loud pedal longer and more often, negating any potential fuel savings. If my driving style did not adapt to the situation then perhaps real world fuel savings would be experienced.
