IMO smaller engines are thought of as more efficient because in order to get the same power out of the smaller engine, you have to run at a higher %load. That's where the higher engine efficiency is coming from--not from the smaller engine itself. If the larger engine were at the same %load, it would be more efficient.
Another thing to remember about running lower rpms is that both friction and pumping losses decrease with speed.
