Campari wins the Mugello Circuit with Alfa Romeo

by Hans Etzrodt
Mugello followed just two weeks after Indianapolis but was a totally different race. The 24 starters at the free formula Mugello Circuit were split into three categories. The favorites included the Masetti brothers and Brilli-Peri in the large Fiats. Six laps around the twisting 64.9 km mountain course had to be completed. After the first lap, the Fiats of Giulio Masetti and his brother Carlo were in the lead with Campari (Alfa Romeo) third ahead of Zaniratti (Fiat), Ferrari (Isotta-Fraschini) and Maserati (Nesseldorf) sixth, followed by a horde of 14 slower cars. Tricca (Storero) and Materazzi (Fiat) retired, Ardizzone (Ardizzone) and Ascari (Alfa Romeo) crashed. After the 2nd lap the order ot the first three remained the same but Ferrari had passed Zanitatti for 4th place, with Maserati still sixth. The Fiats of Bersanti and Pellis retired including Baldoni (Nazzaro) and Corsini (Aquila). After mid-race Giulio Masetti dropped to third place with brother Carlo now in the lead ahead of Campari. Ferrari was 4th, followed by Maserati, Bonfiglioli (Diatto) and another 5 cars trailing. On lap four Giulio Masetti retired, including Maserati and Ansaldi in Nesseldorf cars. The order was then Carlo Masetti, Campari, Ferrari, Bonfiglio, Tarabusi (Diatto), Brilli-Peri (Nazzaro) and the Fiats of Weber and Peyron. On the 5th lap Carlo Masetti crashed, Bonfiglioli and Ferrari retired which left only five cars in the race, Campari ahead of Tarabusi, Weber, Brilli-Peri and Peyron. Thatís how they finished the 6th and last lap.
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 the 1691 turns per lap. Mugello was one of the most important race circuits in Italy and dated back to 1914 when it was called Primo Circuito Toscano. After WW I, the race was held again on June 13, 1920 which was the first race on this 64.9 km route along national and provincial roads with an immensity of turns. From the start at San Piero a Sieve the road was leading anticlockwise along a slight slope through Scarperia at 292 meters altitude, climbing north over 10 kilometers to the Giogo Pass at the considerable height of 879 meters. Then it descended through Rifredo to Firenzuola at 422 meters above sea level. The circuit then turned west past Castro and climbed past La Casetta to Covigliaio at 871 meters. From there the course headed south to reach Futa Pass at 903 meters, which was the highest point. From Futa the road led through Monte Carelli at 314 meters to Maschere from where the circuit snaked east back to start and finish at San Piero a Sieve, 205 meters above sea level,
      Six laps of the 64.9 km route had to be completed, a total of 389.4 km. The Automobile Club di Firenze and the A. C, di Bologna sponsored Il Circuito del Mugello. The cars were split into three categories. The 1st category was up to 3-liter, the 2nd category from 3 to 4.5 liter, the 3rd over 4.5 liter. Prizes were 50,000 Lire between cups, plates, medals and money for the first 4 classified in each category.
Entries:
A list of the 30 entries is at the beginning of this report but only 24 cars started. Great credit goes to Alessandro Silva for providing much information about the cars when unknown.
      The Diatto of Aldo Bonfiglioli was a 4DA type with 2.7-Liter 4-cylinder engine providing 25 hp while Augusto Tarabusi had a 3-Liter model with 4-cylinder (90 x 116 mm) 2952cc engine producing 80/90 hp. With a weight of 900kg, a top speed of 180 km/h could be reached.
      Carlo and Giulio Masetti entered two red Fiat 1914 type 14B/S57 racecars with 4-cylinder (100 x 143 mm) 4492 cc engine, producing 135 hp at 3000 rpm with a race weight of 1150 kg, the estimated maximum speed was 165 km/h.
The #4 car, was a Fiat Tipo 2B 15/20HP, modified by Antonio Ascari. But he drove instead car #14, a 1914 4.5-liter GP Alfa Romeo.
The #7 car of Filippo Ardizzone was called an Ardizzone, a 4-cylinder 2-liter Special, based on Ansaldo.
The #14 Alfa Romeo, was a 1914 Alfa Grand Prix car of which only one car was made with a 4-cylinder (110 x 143 mm) 4490 cc engine, producing 102 hp at 3000 rpm in 1921 and a weight of 1050 kg, driven by Antonio Ascari.
The #16 car, was a 2/30 HP 4.4-liter 4-cylinder Fiat for Guido Materazzi but it was not Emilio Materassi.
The #17 car for Paolo Pellis was a 4.4-Liter 4-cylinder Fiat, "type 3 ter" based on an originally old-fashioned touring model.
The #21 car for Carlo Corsini was an unknown Aquila Italiana, presumably a 4.5-liter straight-six.
The #27 car for Giuseppe Campari, was a 40/60 Alfa based on a 1913 design with a 4-cylinder (110 x 160 mm) 6082 cc engine, producing 82 hp at 2400 rpm, capable of 150 km/h with a racing weight of 1100 kg.
The #19 Nesseldorf was built in Nesseldorf, near Wien (Vienna), Austria, by the Nesseldorfer Wagenbau-Fabriks-Gesellschaft from 1897-1920. An early pre-war model was a 3.3-liter 4-cylinder car, later models were 6-cylinder 40/50 PS and 20/65 PS. After WW I, the borders of Austria were redrawn and Nesseldof became part of Czechoslovakia, renamed Koprivnice. Alfieri Maserati acquired two Nesseldorf, as part of war surplus material, but in shaky condition. He modified he cars to his needs for the Mugello race.
Practice:
On Sunday, June 6th, numerous cars were seen practicing on the difficult hilly course. On Tuesday, official practice started from 5 to 8 in the morning. In those hours the populations of the towns along the course had been warned to abide by the rules adopted by the various local committees not to enter the roads. The drivers covered the dangerous points several times with their cars. Wednesday practiced Ascari, Ferrari and Zaniratti among others. They had a good impression of the route. On Friday morning at around 8.30 during practice, Weber had an accident when a tire burst and he crashed into the wall of a house. Weber was slightly injured and the car was broken, so he had a lot of repair work to be able to start in the race.
Race:
At the San Piero a Sieve finish line were the stands, the pits, the buffets and a large restaurant service. This was the best location to follow the race. The cars started individually in order of their race numbers at intervals of two minutes. However, they were not necessarily released at two-minute intervals. The starting times were determined beforehand according to the race numbers and if cars did not appear at the start (e. g. #4), then car #1 was held to its predetermined time of departure. The start began with Bonfiglioli at 7:04 a.m. and the last was Bersanti who left at 8:04 a.m.

After the first lap, the Fiats of the Masetti brothers were in the lead, Giulio ahead of Carlo, followed by Campari, Zaniratti and Ferrari. Ansaldi (Nesseldorf) stopped at Rifredo due to indisposition, but got back on track. Four cars retired, including Tricca, who burst a tire and overturned his Storero up the climb at Futa. The seriously damaged car could not be repaired while Tricca suffered a head injury. Ardizzone (Ardizzone), had a serious accident a few kilometers from the finish line when the steering broke. Ascari (Alfa Romeo), set out to overtake Baldoni who preceded him at Maschere. Due to the dust raised during the fierce chase, Ascari did not see a pillar in a serpentine hairpin bend and hit the pillar violently with the right rear wheel. The Alfa Romeo overturned and both Ascari and the mechanic were injured, fortunately not seriously. Dr. Crucilla in the Firenze Hospital S. Maria Nuova, released a report, stating that Ascari had a fracture of the lower thigh, chafing on the face and of the right thigh and the external bones of the ankle on the same side; lacerated-bruised wound at the root of the left side of the nose. The mechanic, Bassano Fugazza, 23 years old, had a fracture of the pelvis. Materazzi (Fiat) withdrew due to a broken leaf spring. In adjusted time the 20-car field was in the following order after the 1st lap:

The fast pace remained on the second lap with Giulio Masetti in the lead ahead of brother Carlo and Campari in third place, but Ferrari was now fifth after having passed Zaniratti. Maserati's Nesseldorf followed in sixth place, 15 minutes behind, while the remaining cars were much further back. After 129.8 km, the field was down to 16 cars, following the retirements of Bersanti (Fiat) with a car breakdown and Pellis (Fiat) with a broken engine bearing immediately after the finish. Baldoni (Nazzaro) ended his race when driving past Rifredo due to a broken crankcase. Corsini (Aquila) also retired and Ansaldi fell further behind due to indisposition. The order was as follows after the 2nd lap:
1.Masetti, Giulio (Fiat)1h57m55.8s4500 category

The fight continued fiercely on the third lap. Carlo Masetti passed his brother Giulio who dropped to third place and Campari with a lap of 59m05.6s advanced to second position. Ferrari was 4th ahead of Maserati who was over 20 minutes behind the leader. New retirements included Bergonzini and Pedani, who both were troubled by broken leaf springs. Giunti supposedly ended his race due to an engine bearing failure but it was known that he had used up his spare tires, after having punctured two sets of tires. Rossi dropped out of the race with a car breakdown. The field was now down to 11 cars, after the retirements of Bergonzoni (Beccaria), Zaniratti (Fiat) with a broken engine bearing or due to an accident. Pedani (Fiat) withdrew with a broken leaf spring. The 11-car field was in the following order after the 3rd lap:
1.Masetti, Carlo (Fiat)2h58m23.6s4500 category
2.Campari (Alfa Romeo)3h01m35.6sover 4500 cc

Giulio Masetti, who had led the first two laps, retired with an oil pump failure. His brother Carlo completed the 4th lap in the sensational time of 57m29s at 67.741 km/h. Maserati (Nesseldorf) disappeared when a bearing broke just before Scarperia. Giulio Ansaldi (Nesseldorf) eventually withdrew from the race with indisposition. The car was then taken over by Ansaldi's brother, but the officials disqualified him from the race at the start of the 4th lap. The field was then down to 8 cars in the following order after the 4th lap:
1.Masetti, Carlo (Fiat)3h55m52.6s4500 category

8.Peyron (Fiat)5h48m23.0 s----"----

After five laps, Carlo Masetti who led with a 20-minute advantage to Campari, retired due to a serious accident. At the descent of the Montecarelli road just in front of the villa Marquis Zappi, a rear tire burst, the car swerved and slid into a ditch. Count Masetti remained in bad shape under the heavy car, while the mechanic managed to get away with a little scare. The doctor of Montecarelli who immediately went to visit, established that Masetti fractured three ribs. After having completed the 4th lap Bonfiglioli (Diatto) retired due a broken differential. Ferrari (Isotta Fraschini) who at the end of the fourth lap was third behind his two great rivals, dropped out due to a broken valve. The remaining five drivers were in the following order after the 5th lap:
1.Campari (Alfa Romeo)5h18m11.0sover 4500 category
2.Tarabusi (Diatto)6h25m45.0s3000 cc

4.Peyron (Fiat)7h21m38.6s3000 cc

The sixth lap, which ended without incident, there was no change in the order. Campari passed the finish line, greeted by lively applause. He had lapped the entire field including Tarabusi, Weber, Brilli-Peri and Peyron.
