ELI5: Why does a car having a larger engine capacity mean it's more powerful?

It confuses me... I thought a car having a 2 Litre engine would mean it holds 2 Litres of petrol.. But why would holding more petrol make it faster?

Sorry if this is a stupid question, it's just been playing on my mind recently!




EDIT : Wow so many amazing responses, shows that Reddit is an incredible place full of incredible people, thankyou everyone :)

Not a stupid question, that's the point of this sub.

That volume is not a measurement of how much petrol it holds in the tank, but the space inside of the cylinders. The cylinders are where the pistons compress the fuel mist and then the fuel is ignited. The more space in the cylinders, the more fuel you can spray inside and then explode, and it can explode into a larger volume, meaning it pushes more on the piston, which in turn moves the wheels.
