A native of
Bergamo, he first appeared at the
1928 Italian Grand Prix in one of Scuderia Materassi’s
Talbots. After this race Comotti disappeared from the racing scene, later withdrawing his entry into the
1929 Indianapolis 500. He returned in 1931, winning the cyclecar race at the Circuito di Alessandria in a
Salmson. He then brought an Alfa Romeo Monza sports car to
Scuderia Ferrari in Modena for servicing and became an official driver for the team in 1932. In
1934 Comotti won the
Grand Prix du Comminges for Ferrari. Later that year he finished third at the 1934
Italian Grand Prix together with
Carlo Felice Trossi. Comotti continued to drive for Ferrari until the end of
1935. Comotti left the team at the end of the season and joined Laurie and
Lucy Schell's Ecurie Bleue racing for 1938, driving a
Delahaye. That year he made his first Grand Prix start at
Germany, and also made his only start at
Le Mans. But he retired early in both races. After the war, Comotti became a test driver of the new
Talbot-Lago T26C. He also made some Grand Prix start with that car in
1948. In
1950 Comotti became a test driver for
Scuderia Milano and also made his first World Championship Formula One Grands Prix at the
Italian Grand Prix. He made his second and last World Championship Grand Prix start at the
1952 French Grand Prix, driving a
Ferrari for Scuderia Marzotto. Comotti was one of nine founders of the
Club international des anciens pilotes de Grand Prix F1 (1962). ==Personal life==
