We can change the car and we do change the car.

A new car this year is tens of thousands of components.

Maybe about 50,000 components is what constitutes the car that went to Melbourne.

It's a very large number.

All designed in-house, not necessarily all produced in-house.

And we aim to bring to a race normally maybe 100, 200 new bits.

What we did with Miami is we're way bigger on that number.

So there was...

A new floor, which is aerodynamic performance.

New bodywork, which is aerodynamic performance.

New front wing modifications, aerodynamic performance.

Exhaust blowing at the back, aerodynamic performance.

A new way of operating the power unit, which is just basically power on track and delivery of electrical energy.

And another way of optimizing it as well that was brought to Miami.

We also brought new rear suspension that allowed us to run the car in a slightly different way than we did before and bring the balance window together at the same time and a different way of balancing on rear suspension.

So all of those components I've listed, there's quite a few more projects behind the scenes, but all of those are the big ticket items that each of them deliver quite large amounts of performance when you accumulate them together.

And what you see is it's a relative game.

It doesn't matter if we bring, I'm going to make a number up, two tenths of performance.

If everyone else brings two tenths of performance, you do not move forward.

You need to bring whatever everyone else is bringing plus two or three tenths effectively.
