Alfa Romeo Tipo 33/TT/3

Orazio Satta and Giuseppi Busso had joined Alfa Romeo as designers in 1938 and 1939 and worked together on everything from the 158/159 GP cars to the Tipo T33/3 tubular frame three-litre car of 1972. By 1959, Satta was head of design, while Busso was responsible for mechanical parts from 1948-77. The pair had considered building a 12-cylinder GP car, the 160, in the mid-’50s, and several prototypes were constructed, including a V-8-powered GT car, but it wasn’t until the early 1960s that the OSI Scarabeo coupé emerged.

The Scarabeo first appeared at the Paris Auto Show in September 1966 as a mid-engine coupé, with a transverse four-cylinder Giulia engine behind the driver. Three were constructed, but a spider prototype that was tested in Monza in January 1966 had a longitudinally mounted V-8 and would become the Tipo 33 in 1967.

Carlo Chiti had joined Alfa Romeo in 1952 to work with Giotto Bizzarini. Bizzarini left to join Ferrari in 1958, and Chiti went with him, taking designer Ludovico Chizzola. All three were students of John Cooper’s rear engine designs, and the result was the development of Ferrari’s 156 Shark Nose GP car, in which Phil Hill won the 1961 World F1 Championship. Such a successful year produced upheavals at Ferrari, and most of the competition department quit in November 1961. Chiti left to produce his own F1 car, the under-funded ATS, but it was not successful, and by 1963 he and Chizzola were calculating their next move.

This car was auctioned off by RM Auctions in October of 2011 at the Battersea Evolution, London.
