Mclaren Mercedes MP4-25

I think it's for the braking system.

I have checked on the launch pictures, this inlet was not there...or the floor is assymmetrical?

It IS there. Just look closer. It's a brake duct, used for, ehm, cooling brakes, not for feeding the diffuser

The area I have marked circled....is that just an illusion?

Thanks Pup for showing me how to get pics in

[Pup]

well, i can't get it to work..ignore

Yeah, I think it's just an illusion.

Just saw this picture :

Is this the inlet for one of the decks of the diffuser?

To be fair to Dredge, when you click on the thumbnail and see the full pic, there is an arrow pointing to an opening between the floor and the silver body work.

Its likely to be there to cool a small component, we often see these for cooling control boxes?

By the way, the diffuser works by sucking air from under the car to create low pressure, hence downforce. So any supply hole to the diffuser will be hidden under the floor, and located near the middle, far from an edge

It could maybe be to cool the gearbox/diff or the electronics associated with them.

It's an outlet not an inlet, from inside the side pod outwards.

Button looks too tall for the air to get into the hole under the airbox

Maybe this is the moving valve to switch on and off the air going through the tube that we are not sure of whether it even is a tube to feed the rear wing gap which might not be a gap...
In the corners, under yaw and with the helmet leaning against the cockpit protections, very little air gets into the channel under the airbox, but in the straights, with a centered helmet, lots more air get through and fill the void behind the rear wing...
Something similar is made by mortorbike racers, tuck in during the straights for efficiency and stretch out when braking.

It's since been reported that Button was having seat problems where he was sitting too high in the car. He prefers being sat quite low so this will be corrected by the next test.

From the interview with Button....

Jenson Button: It was a long day! We finished up at about 1am last night trying to get the seat right in the car. Because you obviously have it made in the mock-up, but it is always different when you get in the race car and when you get out on the circuit it is always a bit different as well to what you expected. So we have been doing a lot of work to make me comfortable in the car, initially it wasn't quite where I wanted it to be, I was sitting quite high in the car.

Button and Rosberg can't fit in their cars... Hmmm... sounds suspicious to me in terms of Hamilton and Schumi being given a better view

First up it's been AGES since I last posted (finishing uni & subsequently trying to find a job has taken a lot of time!) but personally, I think the MP4/25 looks amazing. It looks, well, almost futuristic, like something from a sci-fi film...I LOVE it.

On a more serious note, I know its highly unlikely to happen, but I'd absolutely love to hear what Jense thinks of the MP4/25 at this stage in comparison to what he thought of the BGP001 at the same point last year. I've heard stories (Mika Hakkinen in 1998 & Jense in 2009 are the most notable to me atm) of drivers setting out of a car very early in testing and just beaming with confidence in the car, they can just feel it's a winner. I wonder if, over the next few weeks, we can gain an insight into this fro Jense - obviously he won't be saying "This car feels better than my car last year" but maybe his body-language might give us some clues?

The flo-vis doesn't really worry me too much atm. They aren't running random parts from last year's car to try and workout what's wrong with this one, their times aren't appauling, and on long stints I hear the times are fairly good. To me, having used flo-vis so much last year, it could well become a valuable tool this time around, just to look out for any tell-tale warning signs from last year. On the issue of using UV sensitive flo-vis, I reckon the only reason they might not be doing so is because when trying to look at the whole flo patters it must be easier to just look at very obvious lime-freen paint, than to run around with UV flashlights looking at one area at a time. Just my thoughts, I could be totally wrong lol!
