Imagine small carousel at the playground:
If it’s empty and you (the human engine) push it near the center you’ll generate high speed at the edge with not so much effort.
On the other hand if it’s full of people and you’ll try to push near center it will be really hard to do. But! If you push it far from center it’s so much easier. In this case speed is also lower.
You can do similar thing with taking the engine and applying various transmissions to it.
The final answer is: it’s not the engine, transmission makes the biggest difference.
