It should have worked, at one time the personnel included Emerson, Keke Rosberg,Peter Warr, Harvey Postlethwaite , Adrian Newey, and other good people too numerous to mention. Thats a total of a dozen or so world championships and 2 indy 500 wins between them ..
And yet, in 8 complete seasons of F1 participation the net total of achievement amounts to 1 2nd place in 1978, and 2 3rd places in 1980, for emmo and keke, 1 apiece..
So what happened? Certainly the designers of those cars - Divilia, Dave Baldwin, Ralph Bellamy, Caliri, Harvey P. all have solid reputations within the sport and showed their abilities elsewhere.
Emerson had impecable credentials at the start of 1976... Rosberg we now know had as much raw speed as any of his contemporaries..
At times, it seemed that the team lacked direction, at other times finances were tight..
So whats the story - contributions from 'within' welcome, also the Brazilian perspective..
Here is a teaser, F5 in 1978 spec, 'unpodded' at silverstone in 2007 - when is an ensign not an ensign...

so, looking at the tech illustrator thread we have the interesting suggestion that the front end 'flexed' in some way...
looking at the few pictures i have of the car without bodywork i have to say im surprised to read that - certainly i would have expected some flex with a rocker arm suspension, but no more than say on the lotus 78 that fitti f6 designer ralph bellamy had just recently designed at team lotus. ralph was a super good detail man, very careful, very methodical. the top rocker pivot on the fittipaldi appears to be located on outrigged aluminium (and steel?) boxes, whereas on the lotus they were carried on steel frames hung off the side of a narrower chassis. so unless there was a devil in the detail on the fittipaldi that isnt obvious.
now, one other possibility is that the honeycpmb panels, which i beleive originated from the brazilian a/c industry, may not have been correctly laminated to the core? but if that is the case, im not sure how caliri's redesign of the car was intended to address this - it would mean throwing the original tub away, and i dont believe that happened.
so im not sure what all that's about. what i do know is that when a car doesnt work out the box there is usually a long queue of people either directly or peripherally involved, none of whom would be remotely capable of designing a race car themselves, who know EXACTLY what the problem is, and furthermore, they TOLD YOU IT WOULDNT WORK - but usually in a soft enough whisper that you didnt hear...
maybe thats what we're discussing...

Peter,
I have a lot of pictures that show the whole precess of construction of F-5, besides a picture of the model in clay being worked in the center of style and design of GM in São Paolo.
Do I ask for a time to place here because I have that escan it, ok?

Ricardo Divila accompanied the whole project of F-5 that was an adaptation of Ensign closely.
F-6 was an evolution of this, following the tendency of the cars wing.
Could we call Divila for that debate, what do you find?

I assume that for aerodynamic reasons, Bellamy located the front rocker fulcrums further inboard than he'd done on T78, which softens the rocker but stiffens the chassis pick-up. I haven't been able to identify any immediate source of front geometry woes, but I would have thought that as the 79 season progressed geometry became less important as spring rates skyrocketed (or was that later?) - especially on a car with very long suspension arms such as the F6. Having said all that, Caliri did add a truss to the front rockers, and to my casual eye the front roll centre looks untypically low for a Good Year (bias ply) shod car of the period, whereas as low front roll centre/large camber gain seemed to work just fine on the Michelen radial shod Ferraris...which makes me wonder whether Fittipaldi were heading to Clermont-Ferrand for rubber for '79 but had to stop in Acron (Northampton?)? Rocker arm flexure would have had to be pretty severe to upset the geometry (kinematics), but it can certainly play absolute havoc with spring rates and especially damper settings (kinetics).
According to Bellamy in the Motor Sport article the basic problem was flexure of the rear wheel bearings, which can upset pretty much everything.
[Fluff warning: Not surprisingly perhaps, "my" 1979 "Ikantiki" was very much inspired by F6...(although 'twas a turbo straight 4).]

I have only seen the front of the chassis (photos on Racecars Direct some time ago) post-Fly-treatment, and I'm still with Peter 100% that what meets the eye there looks sound, at least as good as Lotus T78.

Anders - is this picture post caliri then? i guess it must be, photo originates from sales brochure from germany a year or two back. what is post bellamy and pre bellamy here? Rocker looks pretty beefy to me - williams fw06 shown for comparison?
interesting that GPI reports as early as south africa that the car had a rear suspension deficiency.. when the caliri version appeared , in germany, it seemed to have everyone puzzled. lots of critiscm of the skirts sticking, poor handling. caliri quoted as saying that the monocque wasnt stiff enough - good job he wasnt given a lotus 79 to sort then... new rear suspension, but no specifics about the front. infact just about everything EXCEPT the front suspension appears to have been redesigned..
wonder what wasnt stiff enough about the tub? details, details...
im sure theres an expert around here who KNEW it wasnt stiff enough...
Paulo - yes please do scan and post, and if you can find Ricardo or Richard Divilia (i think he has posted on here), cross his palm in whatever brazilians cross palms with and get him to post! (dont worry if you dont understand the last bit- english sense of humour!)

In my opinion of lay and searching, do I analyze the front chassis of F-6 as tends little rigidity, I can see the absence of a sub-chassis where you/they would be anchored the suspension triangles similar to the used in Ferrari 312T, it is not even? Anything besides small supports where notice the axes of each arm of the long superior triangles.
The sub-chassis were not common for the fixation and also a fast change in the cinematism? McLaren M23/Shadow DN5/Brabham BT44 /...???

The German sales shots are definitely post-Caliri. If you look closely, you can just see the tubular truss member on the tension side of the rocker - Caliri added those.
At the car's launch there was no tubular strut from the bottom of the tub to the rocker fulcrum, but it was there by the first race in Brazil.
I will grant you that the rocker doesn't look much less beefy than on FW06, certainly not after it was "Caliriized". However, in some of the early season shots it does look more slender to me. Whether F6 had significantly more downforce than FW06 I don't know - if it did, it would've loaded those long cantilever beams more...
Boy, would I love to see some more detail photos of both F6 and F6A under the skin...
In its original form it was such a coherent and homegenous design to look at, wasn't it? The out-the-side exhausts may have spoiled the music, but they did make quite a lot of sense from a packaging stand point (but they could also have blown into the diffuser tunnel...). I also loved the original colour scheme - I have this thing for yellow racing cars

ok - i didnt realise those were later additions, i agree that without them the outer section of the rocker looks slender - i will see what i can find, probably in Grand Prix international - but there arent that many pictures of the original. likewise, you just wouldnt load a rocker pivot without some sort of vertical member - very odd that it didnt have one initially - even to roll out.
it certainly reads like f6 didnt have significant ground effect - but then that wouldnt have been the original plan would it (!) and so if those rockers were undersized, well, thats a bit out of character for RB i would say.

Paulo - your portugese is probably one whole hell of a lot better than mine but i am struggling a bit to understand your post here...
if i understand your thoughts then you are questioning the rigidity of the 'sub chassis' to which the front rocker is attached? i would have said that this is actually a nicer solution than the more common 'plates' seen on virtually every other ground effect car of the era - and also it looks more substantial than the ferrari system, which the f6 layout owes a lot to.
The williams is the best of the lot, but then it isnt a particularly narrow tub by ground effect standards and the offsets are therefore lower.
the mclaren and brabham suspension pickups went straight into the tub here - the brabham was pull rod, the mclaren rocker but both have significant forces fed into the upper tub pickup, as opposed to a pushrod or outboard spring damper pivoting on the lower wishbone. the shadow did have a small overhang for the rocker, which was taken up by a steel fabrication - which was quite substantial.
please scan whatever you have on any of the fittipladi's, it would be great to see pictures of any of the cars in construction. you can be sure that Anders and I will appreciate it!

Ibsen is advancing if to me, he seems also to have very material of the cars in subject.
I already contacted Divila and he kindly were disposed the to explain to us the REALITY of the facts and to help us in relationship our doubts.
Do I ask for some patience again because my day has only 24 hours and of those, do I need to administer the 4 hours that I dispose for my studies and researches, ok?
I can say you that Ricardo Divila is an extremely intelligent person and with good will. Good people!

paulo - so we may be lucky enough to be able to talk to richard via the forum? that would be superb. please keep us informed...
these are the first decent photos ive ever seen of fd04 under the skin - the british press largely ignored it technically, infact pretty much wrote it off when the combination failed to gel.. i've always had a soft spot for it - infact it thought it looked super when first announced, maybe another car that the '76 airbox and wing regs wasnt kind to ? with luck, we will soon know a bit more and not have to speculate.

I'm curious if you're of Scandinavian descent, Ibsen being a fairly common Danish and Norwegian surname.
Peter must think I'm "aping" him in everything I say and do (or else great minds just think alike Peter's is the great mind, I'm just a wannabe). Anyway, I, too, had (have) a soft spot for FD04. 'Stunning' was the effect it had on me when I first saw it in a glorious colour centrespread in its original pre-April 1 '76 aero form - the combination of a full width, low mounted blade and a wide nose was visually quite appealing. WR1 also had that originally, as did Doc's prior 308B and C. I wonder how efficient that setup was - it didn't last for long. I still liked FD04 with the more conventional chisel nose and with low or no airbox - especially after it turned yellow. It appears to be such a compact and neat little car that I often wondered how Divila managed to fit all the fuel in!
I'll have to spend some time poring over the pictures of FD04 and F6 before I make further comments (which will probly sound like an ecco of whatever Peter beats me to...). One thing I did notice off-hand though was the difference in the FD04 scuttle hoops - on the first chassis with Emmo in it, it's a folded and welded sheet metal fabrication (or is it an aluminium honeycomb panel?), on the unrestored tub it's tubular. I would find it odd that the first tub would not be built to the '76 regs, as they would have been known about the time I suspect, and the first scuttle hoop structure looks like it is prepared for forward stays, much more structure than needed just to carry the steering wheel and much taller than necessary for a bulkhead joining the two side members. A change of heart or a nod from FISA?
