1950
340 F1
This thanks to the increase in cylinder capacity from the original 3322 cc to the 4101 cc of the second type. A first engine test on a GP49 type chassis was carried out during the French GP trials, although the cars were not raced.
This version was then only used in a non-championship race – the Nations’ Cup GP in Geneva on 30 July 1950. That is why the 340 does not appear in the official list of Ferrari single-seaters which took part in the F1 world championships, although it was widely used for sports and grand touring cars.
