Before We Lose Track
THE 1975 Grand Prix Ferraris were an entirely new series of cars but they continued the 1974 serial numbers and one final 1974 car was built for the early part of this season, this being 3I2B3/020, which was used in the South American races and was the spare car in South Africa, where the 1975 cars made their first appearance. As the 1975 cars were notable for the 5-speed gearbox being situated between the engine and rear axle line and mounted transversely, instead of out the back and in line with the engine, the new models were loosely dubbed 312T (transversale). T1 started the new series and was number 018 in the 312B3 (flat 12-cylinder) series of cars. Number 019, the second of the transversale cars, was destroyed in a private testing session during the development days of the new model, so that the second car to appear in a race was number 021. All told there have been five 1975 Ferraris in use this season, new cars first appearing in South Africa, at Silverstone for the International Trophy, Monaco and at the Paul Ricard circuit for the French GP.
