Mclaren Mercedes MP4-25

Maybe it's a bit more complicated than I first thought. Still similar in layout to last years from the top. Anyway, is this an air intake at the base of the splitter?

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.

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!!!

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.”

No I am almost sure this duct they are talking about is the top half of the airbox, look at the divider inside of it. If you can't see it fix your displays contrast. It would be silly to have a duct under the airbox that then has to some how go round or through the air intake to exit out the back, it's easier to have the duct at the top like it is.

The tall section of the diffuser is in an area allowed by the rules, and which was exploited last year by several of the teams. So I doubt they'd be using that spot for an outlet - it would be counter productive. Still, the flat black area is a bit of a mystery, isn't it?

Yep, you're probably right, engine lower, other one above. It would make sense that way.

Trick of the camera angle, it's the front of the floor.

Yes. Why does it go through that diffuser/flip up piece? That's what ESP saw in his post. Possibly to increase suction on the pipe exit to create more flow hence more cooling?

... 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.

The selling point, according to Goony, was that it changed the down-force level on the car on the straights compared to the turns.
I think anything is possible here. Remember that adjustable front flaps are legal; meaning this is the only legal movable aero. There could be a completely radical interpretation to this allowance on the new front wing.

Goony just said "dead zone" and everything beyond that was conjecture.

IF there was such a thing, Diesel is probably onto a good point. The area in the middle of the front wing is dead, so use the space to do something useful. Now we have a snow plough splitter in an area that was doing nothing.

Oh, right. Anyway, I can definitely see that they have engineered the crotch of Jenson's overalls a tiny wee bit too high. Tee hee.

i do concede that the floor of the launch car was most likely built solely for the launch.

It is probably a hefty steel floor so the car could be propped up on the central steel tubes?

^^^That big red arrow really doesnt point to anything new or groundbreaking, it is just a flick up to get more DF over the rear axle, they have been there for years... just that in the center of the car the bridgewing is interrupted by the crash structure so it must be placed higher there. It may also have some gearbox cooling air exiting it as well, still nothing new there either.

I think you are right.



Initially it looks like a metal pipe and not carbon.
