Mclaren Mercedes MP4-25

We can easily see the 'roof' of the diffuser just under the brake duct.

theres def something going on at the back there with the diffuser etc.

how would air going into the airbox create a deadzone? sorry i don't know how this works

Look inside the airbox, two channels.

Dead zone located, I was suspecting all this time the inside of the bodywork could be used aerodynamically, however i did not want to spoil it for everybody. After the whole Goony thing from the start of the thread we all avoided the whole deadzone thing. Being a Mclaren fan too, i don't want other teams using Mclaren's innovations

That opening under the air intake, may well be linked to the shark fin round back, Similar to the 2008 Ferrari nose.

I'm not talking about under the airbox, that's just like they had last season and probably isn't an opening, just some clever aero.

No deadzone, it was just bullsh*t from somebody who wanted to make new friends by being a know-it-all.

Inside the air box you can see something at the top sectioning it off. I suspect the bottom half feeds the engine and the top half is for cooling.

The dead zone is hiding behind the unicorn

I see 3 openings. The two you mention in the airbox scoop, but there is also an opening under the scoop, next to the "Boss" logo.

so what does it do? whats so good?

i was reading when it came out from goony but never understood

[dumrick]

I too am shocked they didnt go with the V-nose design, what may be any disadvantages to it?

The V-nose implies a curved bottom of the nose. Since they are using a front splitter, a curved surface would probably allow air to spill upwards, preventing flow stagnation on the upper side of the splitter and reducing its efficience.

Hey F1 techers, first time poster, VERY long time reader.

This may be way off the mark, but what is the possibility that there wont be multi deck diffusers at all....but a maximum use of the what was the upper deck fed by slots? From the limited images we have of the Mclaren it seems the diffuser is the same height the entire width...i do concede that the floor of the launch car was most likely built solely for the launch.

It's not an opening as such, Brawn had it last year, McLaren had the same configuration last year as well. There is no hole through to the engine, how could there be? What's behind that area under the airbox? erm... the Airbox!!!

Good point, I did not think about its interaction with the front splitter.

I'm sure a flick up or a winglet could help you use both concepts together efficiently

I was thinking this as well, that the lower "deck" would be a very shallow plane to make the second deck legal which would be a full height full width channel. Not sure if this is possible though.

... Dead Zone probbly means neutral as in the mandatory neutral area on the front wing. I bet if goony was talking any sense he was talking about this zone at the front of the car and how McLaren have built something to work around it.

That's what I was thinking (but didn't say). 2 inlets for ducts, one for general air flow though the engine compartment, then out the open coke bottle at the back just in front of the bridge wing

There is a separate duct from the airbox - underneath the one that leads to the engine which through the shark fin to components at the rear of the car.

Read the following from the MP4-25 press pack.

The dorsal fin that attaches the top body to the rear wing is very striking – what does it do?

Tim Goss: “The principal knock-on effect of the larger fuel tank was the repositioning of some of the car’s internals. One of the outcomes of that was a decision to move some of the car’s cooling to sit centrally at the rear of the car.

“The dorsal fin is partly to accommodate the additional cooling duct and partly a logical development of the high-downforce wing we ran last year at races like Monaco, which feeds air more efficiently to the rear wing upper element. They’re both quite simple solutions, but they’re actually very neat.”
