Ugo Sivocci

Ugo Sivocci (August 29, 1885 - September 8, 1923) was an Italian racing driver.

[1] Born in Salerno, Sivocci started his racing career as one of the pioneers of Italian bicycle racing,[2] obtaining a second place in the 600 km long classic Corsa Nazionale.

With the HP 20-30 ES Sport he finished 2nd in the Parma - Poggio Berceto race.

In 1923 he began to drive the Alfa Romeo RL, and quickly won numerous races.

Sivocci's car was painted with the green cloverleaf on a white background that was to become Alfa's good luck token.

Quadrifoglio Verde (Green cloverleaf) has been used on Alfa Romeo racing cars since Ugo Sivocci's 1923 Targa Florio entry in Alfa Romeo RL . Originally the white background was a square but after the death of Sivocci was modified to a triangle.
