i really like how they place the sponsers just ahead of the suspension, becuase they know that, thats where people will be taking the pictures

They know what they're doing in Milton Keynes!

Exhaust blown diffuser detail:

Forgive me if I've missed something, but I don't recall the floor having a piece cut out of it that the exhaust blows into before. When did this happen? It's clearly very rough because you can see the ad-hoc cut. They're making a bit of a mockery of the regulations, aren't they? There's quite a bit of mileage left in that line of development. I didn't think that was legal to be honest.

Yes, what you can see there is the pull-rod. Look at where the exhaust is and the airflow around it and you'll realise why a push-rod just won't cut it where you have to do the work around the diffuser this year.

They had it really long ago... I think it was in Valencia. It's legal because of the outer 50mm (or something) regulation, so they can have whatever they want there.

It has been there a long time but it's got nothing to do with the 50mm thing. The floor is cut out so there is no problem. The view above shows that they have cut out more of the floor plate than originally done, however. In effect, the outer part of the diffuser is now just a very short bit of floor with a big (relative to the length of the floor section) diffuser behind it. It's a small version of the Renault method of blowing in to the front of the floor.

It's the one thing that the others should be looking at copying in my view. Ferrari have already done so and I think McLaren should do too if they can. It's a great example of a simple system and makes McLaren's blowing system look what it is - over-complicated.

I stand corrected, but I mentioned the 50mm rule as that defines the maximum size that those cut-outs can be (al least width-wise). Unless I'm wrong again

We're all here to learn, I suppose.

Nope you cut the floor however you want. As long as that cut makes a continuous section if it lies on the step plane. I think RB7 exhausts are actually above the step plane but slight aimed downwards as you can see. The area right at the exhaust tip will be filled in to meet regulations I figure.

Really? Guess I misunderstood what was written earlier....

remember the McLaren cut out floor of two years ago? This is just the same sort of thing. There is no requirement to have the floor plate there at all except where there is bodywork above. The reason is to prevent profiled undersides e.g. "ground effect cars".

Wow. Now I understand why you seemed so confused earlier in this discussion. I mentioned how rough the RB exhaust system looked and you just instantly defended it, obviously not looking at the evidence.

Ok. I don't actually remember the McLaren floor except from fome F1.com articles, because I only got into F1 last year lol. And I can't imagine looking through the whole F1 technical regs. There's too much, and it doesn't help that it's not exactly in layman's talk, is it? All this about mm from this or that line. And there isn't a section labeled "front wing" or "diffuser," which makes it really hard to find what you want

i know this is only a diecast model but look at the floor before the rear tyres, that is what they are on about

Thanks Pedro!
I know it is probably not 100% correct, but still a pretty neat overview (click for high-res):

[bjpower]

the graphic for overtaking in the wake of another car is fantastic

[scarbs]

That's a pretty accurate rendering of KERS and the gearbox......
