Bertone Navajo

A bizarre spaceship, and very late-60s / early 70s design.






"IT'S A TRAP!!" - Admiral Ackbar

Giugiaro Iguana

This is the best one by far IMO. And the most realistic, most producible idea. The details on this car showed up on several other production sports cars.

Bertone Carabo





Where did you think these crazy ass doors came from?


I think it's really interesting that all these designers all used the original classic T33 wheels instead of some other design.

Pininfarina Cuneo Spider

(I think I built a pinewood derby car with the same shape when I was 8 - not a complicated design here)






And a funky variation...

Pininfarina P33 Prototipo





They had recently finished the Dino 246.




Verrry similar to the Ferrari P5 show car....

Such a beauty.

Really shitty records were kept, and they were built in the Autodelta race shop instead of the factory, so there is still a ton of controversy as to how many were actually built (12-ish), the details of each one, who got them, where they are now, and which one is the actual museum car.

There was one blue one, built for an Italian Count helicopter manufacturer. One is thought to have gone to the Shah of Iran, one to a movie starlet. The first Italian customer was a woman who was the World karting champion in 1966 and an Alfa dealer owner. Some were raced in hill climbs and other races. There have been many replicas and copies made, some passed off as real, which makes the record keeping worse.

Some debate over the four rear deck vents vs one long continuous one, and which are originals.

About 5 additional were sent to coachbuilders, who produced some crazy show cars on the chassis. There's a Pininfarina Alfa Romeo 33 Prototipo Speciale from 1969. The Pininfarina Cuneo Spider. The Bertone Carabo. The Giugiaro Iguana. The Bertone Navajo.

Alum 2-liter dohc V8 from the LeMans car, detuned only slightly.

Most believe only two cars were built with the good looking 4 headlight nose. The lights were too low to register it on the street, so the rest have two lights and a different air inlet, more similar to the Porsche 904 nose.

This I think is a replica with a different rear vent detail.

It was in an Italian movie... https://www.youtube.com/watch?v=JdosPODvrVQ


Full disclosure - I learned most of this on the AlfaBB.

German magazine Auto Motor & Sport tested it at Hockenheim in 1969, with a Porsche factory test driver, which is funny. 1000m in 24 seconds.

Alum panels fabricated by a coachbuilder were fit to chassis

Aero tests at new Balocco test track - he didn't like the turbulence behind the wheelwells, which is where the later vent configuration came from. Eventually it was quite slippery.

Tipo 33 Stradale



Alum alloy main structure - built by an aerospace company. Driver sat down in between them. Tubes were lined to carry fuel close to the center of gravity. Later rubber bladders were used.


Magnesium front subframe and rear arms were cast by Campagnolo the wheel and bike people.


Rubber fuel bladder and rear magnesium arms..

shame they never built that. i really like it.

[LateFan]

Looks like a 2600-based concept car, similar to the coupe, both by Pininfarina in the early 60s. (Note - pre Corvette Stingray)

[LateFan]

That's your specially bodied grandmother!

[flyboyx]

what is that? a specially bodied spider?
