I know, I'm the same way. It's crazy to think about and it's crazy to see what manufacturers are doing to improve efficiency. The different ways of tackling the obstacles.
I find these engines nuts because of all the technology behind it. The valves in the intake manifold to change the tract length. The shift phase twin spark. All of it.
