In simple Thermodynamic terms, we’ve gotten better at putting more air and fuel mixture in a smaller space and exploding them more efficiently without destroying the engine.
Better materials, better engineering, better cooling, better air intake, and energy recovery methods all lead up to engines taking more air and fuel into a more compressed state and then harnessing that expansion of volume into mechanical energy.
