'97-'98 for Williams wasn't such a nose dive as 1979-1980 was for Ferrari. The Scuderia went from Constructors' Champions one year to 10th in the Championship the next.

to me, the up close shot of the diffuser is not comforting at all.
they went to scrutineering with the diffuser like that, there's no way they plan to change the design afterwards. imagine how hard the fia would come down on them...
the sight of duct tape holding panels together... on a mclaren?

It's just a very poor fit overall. I'm sure that Mclaren can produce better parts if they wanted to. Apparently they don't want to. Also the holes in the vertical vanes look suspicious to me. are they there to make a toyotastyle vane?

yes, but Renault lost a WDC and Michelin tyres. Mclaren are no different from last year, they have the same personnel, but somehow managed to do a pigs ear of a job interpreting design rules. It beggars belief.

to me, that looks like the holes where they fitted the previous incarnation of diffuser, the rectangular one that looked like it had a blocking plate.

exactly, how long have people been following F1, everything is measured in ,000 and then you think this is poor manufactoring

Scarbs just posted this on another forum:
I agree with the consensus that the Mac diffuser is an interim\disguised double decker design.
If you look with the contrast altered, you can see:
• The way the temporary infill panel in the middle, doesn’t reach the rear axle line, but is cut to avoid the two short fences.
• There are small vertical fences on top of the diffuser capped at 175mm, these would meet up with the exit of the upper deck
• The usual fairing under the gearbox is removed, theres a big void behind the gearbox\under the crash structure for the upper deck.
If the scrutineers pass the designs today, I suspect that Mac will add the upper deck, cut away that split vertical panel and run it on Friday....

couldn't agree more
I can't see how scarbs got all that from the two photo's I've seen. i'm guessing he must be there and seen it for himself. According to his twitter James Allen was waiting in the press office for the stewards final ruling but had to go and meet Brundle for dinner so sacked it off. That's real commitment to the cause, isn't it!!!
Actually, looking at the large photo again, there does appear to be a gap under the crash structure, it's just really out of focus so difficult to make out...
Lewis has confirmed theres no particular problem with the car other than being too slow compared to the competitors via lacking downforce.
Isn't this a car concept problem? The car must be fundamentally flawed because you cannot just gain 20% downforce if you feel thats whats missing...without a change in the whole tub shape of the car.

That's like saying there is no particular problem aside from the engine, which tends to explode.

You know, he might have seen more pictures and be more technically savy than you. Most likely both.

Since there is such an emphasis upon dimensions and in particular height, I think McLaren are in effect submitting just the 'silhouette' of the diffuser to scrutineering. Testing the water as it were. The design seems to hint at an intermediate solution. Perhaps not quite as extreme as the wonderful Brawn example, but a step into that territory nontheless.

No, wingwalker, he is DEFINITELY more technically savy than me!!!! I was just making the point that I couldn't see what he saw, but that's probably because I'm a bit 'special' when it comes to the whole technical side of things. Picking up lots of info on these forums though, which is great, always live and love to learn!

I very much doubt that. I don't think the teams can alter their cars post scrutiny.
I am just wondering if that's what Mclaren wants to achieve, why don't just perforate the device until it looks like a sieve?

yes you are totally right, the teams actually prefer if there is some specific part, or area off the car. Because then its easier to change and adress the problem. I cant remember were ive read it, but many teams in the past has said this. Its a lot harder to make a resonable car without any specific problems, fast.

It just needs the Diffuser Of Justice II ™ DD Edition, and it'll be fine.

It's not like they will remove it during pit stops. It just seems to leave space fror a double decker. The bulge is hollow.

agreed

looks like an intermed solution. Also in some of the pictures you can see the void at the back of the gearbox

Just to burst the bubble folks... they've had that diffuser on the test car:
This is from the tests 2 weeks ago.
Compared with nows:
Now, do you actually think they are gonna just cut that part off, and then re-do their whole aero-map in a few hours? Get real folks.
It is what it is, and they will
not race a substantially modified version of that this weekend.
(Admittedly, they may use a modified version on Friday for testing to get an aeromap done for a few races down the road.)

No bubbles burst here, if you look back a few pages you can see the test diffuser being discussed heavily. True, it isn't assured at all that the plate will be removed, and it sounds like theres a lot of other things to be done to the car to make the diffuser into a double decker, but at the moment it looks like a design thats losing a lot of downforce because its got a whopping great piece of carbon fibre blocking airflow.
I'm not that technically inclined, but I can't imagine that it would be terribly beneficial to race like that?
