then that means you'll burn through 10% more fuel.

And if you've been aggressive with your fuel tank, there perhaps isn't 10% more capacity to put more fuel into your car, especially those races where they're quite fuel heavy.

So there's a conundrum here.

So the only solutions to get around this problem are either you lift the cost cap, so give teams an allowance to revise their fuel tank and make it bigger,

And if you can't do that, then the only other way is to shorten the races.

So you'd have to pull back the number of laps so the fuel doesn't become a problem.

Now I'd have to get my head around, because the fuel's on a calorific... You'd have to increase the calorific, because it's a calorific measurement, not a volumetric measurement.

But the more likely scenario that I've discussed with people is that you do neither.

So people do carry over their chassis.

You increase the fuel flow, but only for qualifying.

So this would then deliver you...

the improvement and step change into qualifying.

So you get more power in qualifying, pull the deployment back.

And then in the races, you pull it back to what it's now.

So everyone's settled in.

And then it's a step change into 28, where all the regulations are across both.

It's not the preferred solution.

From what I understand, FIA and manufacturing teams want everything as agreed package into 27.

But...

Trying to reach agreement on cost cap, trying to reach agreement on chassis allowances and fuel tanks may be too complicated a fight to win and get across the line.
