This Swiss amateur showed more enthusiasm than pace throughout his short career. Funded by a Belgian countess, Toni Branca drove a private Maserati 4CL in Grands Prix from 1947 but made little impression. A lowly 14th in the 1949 Swiss GP, he started the 1950 Swiss and Belgian GPs with a 4CLT and was 10th in the latter.
His was a fuller schedule in 1951 – Branca racing throughout Europe in both Formula 1 and Formula 2. He finished sixth in the non-championship Circuito di Pescara but his Maserati 4CLT/48 retired from the 1951 German GP – his third and final world championship race. Branca travelled to England that autumn for the Goodwood Trophy where he was inadvertently involved in the accident that left Brian Shawe-Taylor in a coma.
Now competing mainly in hillclimbs, he entered the 1955 Le Mans 24 Hours but arrived too late to take part in his last brush with international racing.
