is there any advantage to four cylinders?

Some engine cylinder configurations are naturally balanced. Others need the counter rotating shafts to smooth them out.

pretty sure the m7040 four cylinder have rotating shafts to counter the natural vibrations from the engine. It also has four valves per cylinder for the new low sulphur fuel engine family
