its also the way the cylinders are designed, not just how many there are. usually engines that rev higher are designed with a shorter stroke, and bigger bore, this reduces the momentum from the pistons that the crankshaft has to stop. i would also assume this has some effect on the amount of friction and losses in the engine, but who knows if its better or worse.
im not even going to pretend i know about all the intricacies of engine design.
