Development of 901 Convertible, Prototyp (built 1964)

Re the 901 Convertible Prototyp Chassis 13360 I recently read an interesting by German Journalist Wolfgang who posted it on a swiss website.

I thought that they repeat infos I read (plus a few faults..) but actually it many infos published by Aichele’s book published 20 ago. Aichele description is the most detailed literature this theme. BUT the interesting is however that this new reports a few infos unknown to me and I beleive until today have been never in any literature about the 901/902 It cites several employees of and Porsche, some have interviewed by Aichele before, never.

Here is the text translated from german to (I shortened it a bit and corrected google

The mysterious forerunner — the 901 of 1964 (and his successful

« What is so special about the 901 ancestor of the fully open which came finally on in 1982?

Why it was not immediately produced? And did 13360 had an to the 911 Targa, the variant which the long convertible-absent Porsche period ?.

Before it comes to above issues, the history of the Porsche 911 is often told this: When the factory the 356 successor 901 in the early 60ies, in the US all were treated to be banned by safety laws, initiated by the consumer advocate Ralph In response, Porsche anticipated the convertible ban in their core market: the legacy of the successful 356 would receive stable bars and became the 911 Targa the first security convertible in the

Sounds as logical as romantic. But it is

1st: Neither Nader nor else at that time 60ies) talked about a convertible ban.

2nd: in the years of 356 production, the sale of 356 was so unsuccessful that the actual of the 901 took place without any of an open version.

3rd: the factory version of rollover for an open 901 lead them to a bar is wrong and that it rather was the solution of a technical compromise.

that provoke and proofs are Reboot for the real story:

Upheaval and cost pressure for

When Porsche outlined its sports cars in the late the company was in transition. The need for in performance and road behavior a further position away the usual Volkswagen-based technology.

At the time the growing influence of the Porsche brought fresh air and unrest among the old grandees. Alexander Butzi Porsche is Head of Styling while Komenda is relegated to second in even Komenda was -since the 30ies- Chief of DesignKonstruction Later Butzi’s cousin, Piлch replaced long-time director Huschke von Hanstein. upheaval in the house of Porsche fierce arguments over how the 356 car -the 901- should and what technology would be to the new car.

The 901 is also more during the design phase and much more expensive to Increasingly, questions were which 901 parts could be less expensive all while were getting tighter.

356 Cabriolet.

In 1962, radical cutting for the 901 development were — including the courageous to kill the open 901 variant Reason for this were the sharp decline of sales of 356’s. In 1960, 356 convertible were 41.6 percent of production, in 1961 they to 27.2 percent and 1962 further down to 19.8 further decline was expected. In -the last full only 1745 of a total of cars built were a meager 16.9 percent of number of units.

And, in a clear contradiction to literature, the often cited of the «coveted 356 Cabriolet » can be now questioned. it is said, open 356 were a 35 of sales. But this reflects the final year of 1965, ended in September. From 1965 on, the 911/912 Coupe already off the production line and by end of 588 356 Convertible are built but only 356 Coupes and also combined units of the new 911/912 Coupe’s. In words, in 1965, only one of Porsche’s built were cars.

Conceptional abandon of an 901 version

Above production/sale speak for themselves. Nevertheless, the abandonment of an open version of the 901 today incredible. Especially why were never officially But the memory of some 901 body is intact. In addition to the Coupe was no other body structure of a discussion, says Sylvester von (81), responsable as a designer for the doors and hood at Porsche’s builder, Reutter. Its predecessor, the convertible fan Reinhard Schmдdicke underpins . Butzi told me clearly that no Cabriolet is And Erwin Komenda put it even clearly by saying that he was opposed to any unnecessary hole in the

Nevertheless, in the second half of there were several plans created for a fresh-air-901. For reasons most use the Coupe’s including their window But no decision to actually built a car were made.

The fact there was finally deciced to one — a decision made in 1964. nine months the debut of the 901 at the IAA — was due to the marketing Ferry Porsche’s nephew Wagner (now 90), Head of Sales Germany and the convertible supporter had not given up: evidence for a new convertible sales are reported from the USA.

On 2 September 1964, the Porsche’s production planning for the period to end of 1965 is defined: 5000 901 and 902 Coupe and 1000 «open Eight days later, on 10th, Karmann provides the convertible prototype, chassis 13360 to Porsche’s testing delivered without any roof

This was planned to be done in by Porsche convertible specialist Schrцder. He worked before in at Convertible manufacturer Karl and after 1952 at Ramseier work Worblaufen, Switzerland). afterwards he landed at Karmann he was responsible for the VW Karmann Ghia as well as the Beetle convertible by Finally, in 1956 he joined

There were neccessary to be made that would the 901 Coupe enough rigid for a For Wolfgang Eyb (89), then of the 901’s body structure, it was a plan: If a car will be configured in an and in fixed head version you only the open version and the closed version is based on it. the basic structure of the 901 was provided for a Coupe, we then should done it the other way around which was impossible. Stiffness of the 901 was always inadequate.

Eugen (77), a then young in Schroeder’s team, gives an of the dilemma: We even called the Fritz Martin back the retirement and let him draw and calculate for two

At the end he said: The open 901, you can After many desperate tests at the factory we finally an idea that was thought out in but initially hacked as the team it was the aesthetic’s worst case but the only realistic compromise: the welded roll cage.
