History: |
|
| The development of
sports car races in the period after the war was stimulated by Le Mans,
the Mille Miglia and the introduction of the World Marque Championship in
1953 which had seen the A6GCS perform creditably in this period. In
1954, following the same path as with the A6GCS, an engine from the 250F
was placed in an A6GCS, with reduced compression and run on standard fuel
at a compression ratio of 9:1. This was the first 250S and it was
intended for the 1954 Mille Miglia. Then the Supercortemaggiore GP
was moved from Merano to Monza and open for 3.0 litres and this event saw
the first true 250S. Two cars were entered, but both retired - the
250S was placed on hold. Encouraged by new regulations for the 1956
Le Mans which favoured sports cars of 2.5 litres, a new prototype was
built, making the third 250S. It took part in races without success
in Africa at Agadir, Perdisa and at Dakar with Musy. The two cars
entered at Le Mans had technical failures and that was the end of the 250S
in that form - later a 4 cylinder version would make an appearance. |
