Brilli-Peri wins the Mugello Circuit

by Hans Etzrodt

The 23 starters at the 1923 Mugello Circuit race were split into two groups of Production Cars and Racing Cars, resulting in six categories. The favorites included Brilli-Peri (Steyr), Maserati (Diatto Special) and the Alfa Romeos of Giulio Masetti and Ascari. The battle for the lead was between Brilli-Peri and Masetti with Ascari once in second place. After more than five hours, Brilli Peri dominated as the overall victor winning the Production Car group while Masetti won the Racing Car group. Ascari was third, followed by nine other finishers, one car was flagged off and nine cars retired.

The races on Circuito del Mugello north of Florence in the Toscana region of central Italy, were also called the "Little Targa Florio" because of its many up and downs and its 1691 turns per lap. Mugello was one of the most important race circuits in Italy and dates back to 1914 when it was called Primo Circuito Toscano.
After WW I, the race was held annually since 1920 and in 1923 it took place for the 5th time on its 64.900 km route. The start was at San Piero a Sieve, 205 meters above sea level, leading with a relatively slight slope to Scarperia, 292 meters. From here the road climbed in just over 10 kilometers to Giogo Pass at the considerable height of 879 meters. From Giogo Pass it descended to Fiorenzuola at 422 meters above sea level and then it climbed again to reach Futa Pass at 903 meters, which was the highest point of the circuit. From Futa the circuit led through Montecarelli to Bivio di Novoli and returned to San Piero a Sieve. Six laps had to be completed, a total of 389.400 km. The Automobile Club di Firenze organized this event under the supervision of the Commissione Sportiva del R.A.C.I. (Reale Automobile Club d'Italia). Besides cash prizes, for the first time a very rich Trophy of Marquis Ginori-Lisci, the magnificent Ginori Trophy, and other artistic gifts were at stake.

Entries:
A list of the 33 entries is at the beginning of this report of which 23 cars appeared at the start. Alfieri Maserati raced one of his Diatto Specials with a 5.8-Liter Hispano-Suiza Aero engine. The 3.0-Liter Alfa Romeo RLTF23 was considered a production car and started in the Production Car group, while Masetti's Alfa Romeo RLTF23 was re-bored to 3.154-Liter and therefore not a production car and started in the Racing Car group. The Steyr production car of Brilli-Peri was the same type he had raced at the Targa Florio.
According to Alessandro Silva, Albiono Marinoni was Ansaldo's test driver and entered for this race, while Attilio Marinoni was Masetti's riding mechanic.

Race:
A large crowd was assembled along the entire route of the classic Mugello Circuit. The organization of the Firence Automobile Club appeared exemplary. At six o'clock the Circuit was cleared and whoever was on it had to leave without being able to continue to their destination. At any point of the circuit, both in the open countryside and inside the inhabited areas, during the race it was absolutely forbidden to drive at all, including officials assigned to keep order. The start was at San Piero a Sieve. The cars started individually in order of their race numbers at intervals of one minute and three minutes to the 1500 category and five minutes between the other categories. However, the cars were not necessarily released at one-minute intervals. The starting times were determined beforehand according to the race numbers and if cars did not appear at the start (e.g. #14), then the car #15 was held to its predetermined time of departure. The start began at 7:00 in the morning and the last car left at 7:50.
