Alfa Romeo 6c 1750 Gran Sport Testa Fissa

'Testa fissa' means 'fixed head', a non detachable cylinder head. Before 1931, the regulations of the Irish Tourist Trophy (TT) stipulated that the cylinder head had to be detachable.

So the Italians applied blind screws which nevertheless could turn. The scrutineers looked no further... Acquiring engineer Vittorio Jano proved to be a coup for Alfa Romeo, as the successor to the 1500, the 6C 1750, did extremely well. The six-cylinder, fitted with a compressor in the Gran Sport and Super Sport versions, triumphed all over Europe. In 1929, 25 of the 26 6C 1750s entered completed the Mille Miglia. The Testa Fissa on display here took part in the Mille Miglia of 1934, driven by Nino Farina who in 1950 became the first Formula 1 World Champion.
