And those concerns have come from drivers.

They've led this.

They've had the dialogue with the FIA.

The FIA has had the...

kind of been empowered by this.

We know Mohammed Ben Salaim loves it when he's kind of in dialogue with the drivers and pushing on.

So he's been speaking to them.

They've made some progress.

And I think this is what's pushed things across the line.

It's not there yet.

We can't wave the checkered flag and think everything's now sorted with these regulations.

They're going to be brilliant from 27.

But this is a critical first step to get everyone on board with the idea, at least, even if the devil's in the detail.

And that detail is going to be very complicated.

One of the biggest ones is chassis, actually, bizarrely, even though we're talking about power units.

The biggest complication from what I understand is the chassis that under the cost cap, based on how much work teams have had to do this year and some kind of re...

structuring of the processes with cost cap because it's a new form of cost cap this year with more inclusions but teams have found themselves pushed to the top of the ceiling into this season so from what we understand around half the grid was planning on carrying over the chassis to

into next year um they felt that it wasn't a critical performance area for these regulations it made sense to roll it into 27 gives people some more headroom next year for development in other areas of the car and works well the problem with that is the chassis includes the fuel tank

And the fuel tank is based on the size of the fuel tank is based on the amount of fuel needed to go into the power unit based on the fuel flow.

So if you increase the fuel flow for next year to deliver this extra power, so from what I understand, fuel flow grew up by 10%.
