The information within these pages was derived primarily from contemporary magazines and newspapers. I am indebted to all those outstanding journalists and newsmen for their dedicated reporting. Without their stories, we would not have learned about what happened at these events. Secondary sources have also been helpful but to a much lesser extent. Several others have given valuable advice and corrected errors. I extend my appreciation to all those helpful specialists and enthusiasts. I give particular thanks to Tony Kaye for patiently editing the the text for the major race reports. Lastly, I am immensely grateful to Leif Snellman for providing a site where these factual and elaborate accounts can enable us to relive these long-ago races and also for his incredible lifelike drawings.

1925 was the last year of the 2-liter formula. Of the 24 races for 2-liter racecars only seven were considered major events. Four of those races counted towards the inaugural automobile World Championship. Alfa Romeo had the best car and drivers, using previous year's proven design but refined for 1925. The two fastest grand prix cars were Alfa Romeo with 225 km/h top speed and Delage at 215 km/h. Malcolm Campbell, (Sunbeam) established a new World Land Speed Record on July 21 at 150.766 mph or 242.635 km/h.

The 1925 Formula
was referred to simply as the 2-liter formula, with a maximum engine capacity of 2.0-liters. Riding mechanics were banned in the Grandes Épreuves, but the empty seat had to be in place. However, this rule was not strictly applied at other events like the Rome Grand Prix, the JCC 200 miles and others. For the first time, driving mirrors were obligatory. The minimum unloaded weight had to be at least 650 kg - 1433 lb. and the minimum body width was 80 cm - 31.5 in. Repair and replenishment of the car during the race all pit work was restricted to the driver and one mechanic.
      Indianapolis was part of the World Championship, where the engine size was reduced to 122 cubic inches, to match the 2-liter Grand Prix formula. But the cars were single seaters and the body width was smaller.
      Formula Libre without the 2.0-liter formula restrictions worked well and produced good racing, allowing older cars with larger engines to contest non-World Championship Grand Prix races.
      Targa Florio and Coppa Florio regulations were for racing cars divided into 5 categories: up to 1100 cc, 1500 cc, 2000 cc, 3000 cc and over 3000 cc. The minimum unloaded weight was 120 kg. Each car had to be occupied by the driver and the riding mechanic sitting side by side. They could be substituted during the race by a driver and riding mechanic who had been nominated before the race. This substitution could only take place at the end of a lap in the presence of an official. The mechanic was not permitted to drive. Only those who completed the race within one hour of the first car in their class would be classified, and the maximum allowable time was 10 hours. The entry fee for each car was 1000 lires per race and 1500 lires for both, the Targa and Coppa Florio.

The Races
Only the national clubs of Belgium, France and Italy held races to the international Grand Prix formula. Indianapolis was run to a different formula, although the engine size was the same. Other major events like the Rome Grand Prix, Targa Florio and San Sebastian Grand Prix were held to formula libre, bringing the total to seven major races.
      There were an additional 17 minor events for Grand Prix cars, the Provence Grand Prix at Miramas, Tripoli Grand Prix in Africa, Alessandria Circuit, Solitude-Rennen at Stuttgart, Grand Prix d'Overture at Montlhéry, Savio Circuit at Ravenna, Coppa della Perugina at Perugia, Mugello Circuit at Mugello, Coppa Etna at Catana, Eifelrennen at Nideggen, Coppa Acerbo at Pescara, Coppa Vinci at Messina, Coppa Montenero at Livorno, Taunus-Rennen at Wehrheim, Boulogne Grand Prix, JCC 200 Miles at Brooklands and Garda Circuit at Salo. The remaining races were less important, minor national events of a club type nature.

The 1925 World Championship
was organized by the CSI (Commission Sportive Internationale) of the AIACR (Association Internationale des Automobile Clubs Reconnus) in Paris. This first World Championship for constructors was won by Alfa Romeo. The Spanish Grand Prix was omitted from the 1925 World Championship for unknown reasons but allegedly due to an incident 1924 at Rabassada near Barcelona, which resulted end of 1924 in a 5-year disqualification of Alfieri Maserati by the CSI and a somewhat shorter ban for Diatto. Possibly in retaliation, evidently the Italian delegation within the CSI had enough influence, as organizer of the championship, to prevent Spain having a Grande Épreuve that year. Whether this is true or not, remains a matter of conjecture. In previous years the reason for Spanish GP cancellations was usually of a financial nature, so it is quite possible that Spain withdrew from the 1925 World Championship due to financial reasons. Following WW I, German cars and drivers were excluded from GP racing in France, Belgium and Britain. The CSI banned German competitors from participating in the 1925 Automobile World Championship. But in May 1925, the German Automobile Club was re-admitted into the AIACR and in November 1925, Germany became part of the CSI with 12 to 2 votes where America and Belgium were against the acceptance. Four votes abstained, amongst them Czechoslovakia. There were representatives present from 18 nations. More about it here.

Factory Racing Teams

car SA Italiana Ing. Nicola Romeo & C. (Milan, Italy)
Alfa Romeo entered their cars, which were built by the factory-racing department. The great designer Vittorio Jano led a team, which in 1924 had conceived and built a new Grand Prix car, the tipo P2 with a 1,987 cc, 8-cylinder, twin o.h.c. s/c engine, producing 140 hp at 5,500 rpm, giving a top speed of 225 km/h. During its first year in 1924, this car had won major races. For 1925, the last year of the 2-liter formula, the proven P2's were fitted with bigger brake drums and the power was raised to 155 hp by fine-tuning and using a special blend of fuel, producing a maximum speed of 240 km/h for their drivers Antonio Ascari, Giuseppe Campari and Gastone Brilli-Peri. After Ascari lost his life at the French Grand Prix, Peter DePaolo drove the third Alfa Romeo at Monza.

car Automobiles Ettore Bugatti (Molsheim, France)
Bugatti appeared in 1924 with their new Type 35, a 1,991 cc, 8-cylinder, delivering 90 hp at 6,000 rpm. In early 1925 this car had already won the Rome GP and the Targa Florio, but the cars did not appear at the European Grand Prix at Spa, let alone at Indianapolis. Five T35 models without superchargers then raced at the French Grand Prix, for Meo Costantini, the brothers Fernando and Pierre de Vizcaya, Giulio Foresti and Jules Goux. For the last race, the Italian Grand Prix at Monza, Bugatti produced five Type 35 with 1,493 cc, 8-cylinder, unblown engines, better known as the Type 39. H.G. Conway mentions in his book 'Grand Prix Bugatti' about records indicating that these were originally the cars driven at the 1925 A.C.F. Touring Grand Prix.

car Chiribiri & Co. (Turin, Italy)
Chiribiri built little sports and racing cars in 1921. These had a pushrod-operated o.h.v. 4-cylinder engine of 1,453 cc, giving a top speed of 110 km/h. In 1922, am improved "Monza" type was produced with a 1,486 cc, 4-cylinder, twin o.h.c. engine, producing 72 hp at 5,100 rpm. These Voiturettes were able to reach speeds of 165 km/h, and were driven initially by 'Deo' Chiribiri and Jack Scales and in 1923 by Tazio Nuvolari amongst others. The only appearance of Chiribiri in the 1925 World Championship was at the Italian Grand Prix, where Luigi Platè and Santoleri retired both of these Voiturettes.

car Automobiles Delage (Courbevoie, Paris, France)
Delage racing cars had been in existence since 1906 and were produced in Louis Delage's factory in Paris. In 1923 when the 2-liter formula came into being, Delage produced the 2LCV Grand Prix car with a four o.h.c. V-12 engine initially giving 105 hp. Except for some experiments, during the following year the 2LCV ran without blowers but for 1925 the 1,983 cc, V-12 engine came with twin Roots superchargers, increasing the power to 190 hp at 7,000 rpm and the top speed to 215 km/h, figures which were unprecedented. The car had a chassis incapable of handling this much power so the car's full potential was not realized. Nevertheless, the Delage was the only car that could almost compete with Alfa Romeo. Delage drivers for 1925 initially included René Thomas, Albert Divo, Robert Benoist and Paul Torchy. Later Louis Wagner joined the team after Louis Delage fired René Thomas following Delage's debacle in the 1925 European Grand Prix.
      At the European Grand Prix at Spa on June 28, 1925, four 12-cylinder Delages were entered for Albert Divo, René Thomas, Paul Torchy and Robert Benoist. The 1925 Delage was lower and better streamlined than the previous year's model. The hood was now heavily louvered to dissipate the enormous heat generated by the V-12 engine, which was now equipped with a Roots blower on each bank of cylinders, boosting the power output to 205 hp. During this first race, the engines of the four cars all expired with connecting rods coming through the crankcase to describe their problems briefly. Griffith Borgeson stated, "The blame would seem to have been Lory's for miscalculating the piston pressures that supercharging would give him." This serious problem had to be resolved immediately by the Delage team chief René Thomas and the car's designer Albert Lory since the next race, the French Grand Prix, was just four weeks away. Griff added that after the race team morale was low and fingers were pointed at René Thomas, for pocketing the accessory money. Consequently, Louis Delage became involved, studying the contracts with the accessory firms, firing Thomas, and hiring Louis Wagner to take his place. Delage then had the contracts rewritten in his own name.

car SA Autocostruzioni Diatto (Turin, Italy)
Diatto had started building Cléments under license in 1905. At the beginning of the 2-liter formula in 1922, they produced the Diatto 20S with a 1,997 cc, 4-cylinder engine, delivering 75 hp at 4,500 rpm and a top speed of 155 km/h. Alfieri Maserati designed the 1925 Diatto grand prix car with a 1,982 cc, 8-cylinder engine, delivering 130 hp at 5,600 rpm and reaching a top speed of 175 km/h. The drivers were Alfieri Maserati, his brother Ernesto and Emilio Materassi. When the Diatto Company withdrew from racing at the end of 1925, Alfieri Maserati left to start his own company with his brothers.

car Duesenberg Inc. (Des Moines, Iowa, USA)
The Duesenberg brothers had emigrated from Germany to America when still children and in 1903, started an automobile supply company in Iowa. Duesenberg racing cars first appeared in 1914. After their great victory in the 1921 French Grand Prix, for 1923 they produced the Type 122 in reference to the engine's size in cubic inches. This monoposto had a 1,984 cc, 8-cylinder engine, giving 150 hp at 6,000 rpm, and won the Indianapolis 500 in the hands of Peter DePaolo and his relief driver Norman Batten. Duesenberg appeared at Monza with two cars for Tommy Milton and Peter Kreis. Instead of driving for the Duesenberg Brothers at Monza, DePaolo handled the third Alfa Romeo.

car Fiat SpA (Turin, Italy)
Fiat had built race cars since 1904. In 1923 they raced their tipo 805 which had a 1,979 cc, straight 8-cylinder supercharged engine, producing 130 hp at 5,500 rpm and won that year's Italian Grand Prix at Monza. For the following season these machines were further developed to produce nearly 150 hp but were raced without success. This failure was probably a contributory factor to Fiat's departure from grand prix racing. During 1924, one tipo 805 was prepared with a monoposto body to race at some American track races. The presence of Fiat's Chief Engineer, Francisco Rosso, may have helped Pietro Bordino set a record of 131.6 mph to become the pole-sitter at the new Culver City board track race on December 14, 1924. In 1925, Bordino came sixth at the Culver City 250 Mile Race and retired at the Charlotte 250 with a broken rear wheel. He then entered and drove the 805 monoposto at Indianapolis, where the car covered the full race distance of 200 laps and finished tenth with assistance from his French relief driver Antoine Mourre, who took over after Bordino injured his hand and had to go to hospital. This was the only occasion that a Fiat appeared at a World Championship event but Indianapolis was not an official works effort.

car Ets Albert Guyot et Cie (Clichy, Seine)
The Guyot Spéciale was produced by Albert Guyot who had been employed for years by Rolland-Pilain as a technician and driver. In 1924, he established the company Albert Guyot & Ci. Besides some touring cars, a few racecars were his better-known products. The first Guyot-Special appeared in 1925. It was based on a Rolland-Pillain chassis with a 6-cylinder, 1,984 cc sleeve-valve engine, built to Burt-McCallum patents. With a Cozette supercharger the engine produced 125 hp at 5,500 rpm, giving the car a maximum speed of 193 km/h. The Guyot-Special did not take part at its national race, the French Grand Prix, but was entered at Monza where just one of the three existing cars appeared. Later that year two Guyot-Specials were entered for the San Sebastian Grand Prix, but did not appear.

car Daimler Motoren Gesellschaft (Stuttgart-Untertürkheim, Germany)
Mercedes had successfully raced their 1924 TF, a 2-liter 4-cylinder car, in the 1924 Targa Florio. At the Italian Grand Prix six months later, they entered four newly designed Grand Prix cars with blown 2-liter 8-cylinder M218-engines, producing 170 hp at 7,000 rpm, and a top speed of 210 km/h. The team was withdrawn after Zborowsky, one of the team's drivers, had crashed fatally after 43 laps. The German company announced that they would not enter at any international events in 1925. The Mercedes driven by Christian Werner at the 1925 Rome GP was not a works' entry.
      The ban after WW I, which applied to German cars and drivers, had extended only to the French and European Grands Prix and was apparently still in effect because in their February 1925 meeting, the International Sporting Commission of the AIACR banned German competitors from participating in the Automobile World Championship. However, at the May 5, 1925 AIACR meeting in Paris, the German Automobile Club was readmitted into the International Association. The voting was twelve in favor, two against, and four neutral. Later that year, at the AIACR October conference in Paris, with the recommendation of the ACF, it was decided that Germany should be represented on the CSI (International Sporting Commission) of the AIACR. The racing circuit at Linas-Montlhéry even invited the German industry to participate in their opening race in May 1925.

car Miller Motors Inc. (Los Angeles, California, USA)
Miller established a business in about 1907 in Los Angeles which was owned by Harry Armenius Miller. In 1916, Miller designed his first racing engine and car. During 1920, a new 2,999 cc, 8-cylinder monoposto was produced. Miller engines were designed for the American speedways, where they powered the winning cars at Indianapolis from 1922 to 1924. The 1925 Miller 122 monoposto had a very narrow single-seater body with a 1,977 cc, 8-cylinder, supercharged engine, producing 200 hp at 5,800 rpm. A Miller which was privately entered by Harry Hartz came fourth at Indianapolis, while the only factory Miller, driven by Bennett Hill, retired after 69 laps. Millers were not entered at any of the other three races of the 1925 World Championship.

car Sunbeam Motor Car Company Ltd, (Wolverhamton, Staffs., England)
Their racing history went back as far as 1907. In 1922, the beginning of the 2-liter formula, they raced a 4-cylinder car but progressed the following year with a 6-cylinder engine, capable of 106 hp. For the 1924 season, Sunbeam lowered the chassis and fitted a 1,988 cc, 6-cylinder, blown engine, producing 138 hp at 5,500 rpm, bringing the top speed to 200 km/h. These cars were then entered at the 1925 French Grand Prix for Henry Segrave, Giulio Masetti and Caberto Conelli, the only race of the Championship in which the cars appeared. At season's end Conelli raced one Sunbeam at the San Sebastian Grand Prix where it retired.

Independent Racing Team

car Eldridge-Special
These were 1.5- Liter cars built by the English driver Ernest Eldridge. Although he had produced several Eldridge Specials with large engines, only the smaller versions that appeared in 1925 are of interest here. His first small car had a 1,496 cc, 4-cylinder, Anzani side valve supercharged engine, giving 80 hp at 5,500 rpm. It was mounted in an Amilcar Grand Sport chassis, and reached 181 km/h over a flying kilometer. With this design he finished fourth at the Grand Prix de l'Ouverture at Montlhéry. This car was followed by a very low-built chassis of his design which was equipped with the same 1.5-liter engine. Eldridge raced this car without success at the Italian and San Sebastian Grands Prix.


The success of drivers in Major Grand Prix races can be found in the list of 1925 Major Grand Prix Races.

Antonio Ascari, 36, started driving in 1911 with a De Vecchi at a Modena touring event and thereafter joined ALFA as test driver. In 1919 he won the important Parma-Poggio di Berceto and Coppa della Consuma hill climbs with his own 4.5-L Fiat racecar. He drove for the Alfa Romeo team in 1921 and won the Parma-Poggio di Berceto hill climb but crashed at Mugello. At the 1922 Targa Florio he crashed once again, this time on the first lap. In the 1923 Targa Florio he finished second in an Alfa Romeo and won at the following Cremona Circuit. In 1924 he established a 10 km world record at 195 km/h on the long Cremona straight and won the Parma-Poggio di Berceto hill climb. While leading the Targa Florio his Alfa Romeo spun to a halt with a seized engine on the last lap only 200 meters from the finish. At the European Grand Prix at Lyon he also retired while in the lead. Finally, at the Italian Grand Prix he won the race in superb fashion. In 1925 he won the European Grand Prix at Spa-Francorchamps. At the following French Grand Prix, Ascari crashed at high speed on lap 23 and his car overturned. He died shortly afterwards in the ambulance which was bringing him to a hospital in Paris.

Albert Divo, 30, began in 1919 as a riding mechanic for René Thomas in a Sunbeam. He moved with Thomas to Talbot and in 1922 when Thomas left the team, Divo became a driver for Talbot. In 1923 Divo finished second in the French Grand Prix and won at the Sitges Oval. In 1924, he raced for Delage winning several races. As a Bugatti works driver he won the 1925 French Grand Prix with Robert Benoist and also won the San Sebastian Grand Prix with André Morel at the end of the year.

Count Carlo Masetti, 27, won the 1925 Rome Grand Prix. He had a younger brother, Giulio who was more famous. Both raced in the 1919 Targa Florio, Carlo placed fourth in an Aquila-Italiana and Giulio was sixth in a Fiat. In 1922 Carlo won the Coppa Montenero driving a Bugatti and also won hill climbs at Rome.

Gastone Brilli Peri, 32, won the 1925 Italian Grand Prix and was proclaimed for winning the World Championship for Alfa Romeo. He was born in Montevarchi near Florence and started racing motorcycles but changed to racecars in 1920, first with a Nazarro and then a Fiat. He placed second at Mugello in 1922 and won several hill climbs. During 1922 he entered a Steyr in the Targa Florio, where he crashed about 15 km from Cerda after completing three laps in eleventh place. He received serious injuries. He mainly raced the Steyr until the end of 1924. He won in 1925 at Mugello and Parma-Poggio di Berceto hill climb in a 4.5-liter Fiat. In August of 1925 at the 15.5 km Coppa Pistoiese hill climb near Florence he set FTD in his 3-liter Diatto racecar and at the Montenero Circuit he made the fastest lap before retiring his Diatto. In 1925 he joined the Alfa Romeo Factory team, culminating with his victory in the 1925 Italian Grand Prix, which won Alfa Romeo the World Championship. In some smaller events in 1925 he raced his Ballot, winning the 1925 Perugia Cup.

Bartolomeo "Meo" Costantini, 36, was Italian and the most successful driver in 1925. After winning the Targa Florio he finished fourth in the French Grand Prix and third in the Italian Grand Prix. His first race was with the Aquila-Italiana works team at the 1914 Targa Florio including a few other races. After the war in 1920 he raced a 1500 Bugatti T13, and in the following year with the same car he finished second at the Garda circuit. In 1922 he raced a Bianchi 18 and in 1923 with an 1100 Amilcar he finished first in class at the Coppa delle Alpi. In 1923 Costantini joined Bugatti in a role that would change while he remained in Molsheim. The official standing of Costantini in the Bugatti factory was not known. He was undoubtedly very close to the Bugatti family's inner circle. He prepared racing cars and he won races with them in a manner which no other has equaled. Costantini started as a test driver and sports director in 1924 and became the team leader. At the September 1924 San Sebstian GP in Spain, he finished second in a T35 to Segrave's winning Sunbeam. In May 1925 Costantini won the Targa Florio with a T35. The Italian was victorious at the 950 km French Touring Car Grand Prix at Montlhéry with a 1500 cc T39 Bugatti after over 11 hours behind the wheel. At the 800 km Italian GP he finished third overall with the T39 and won the 1500 cc category.

Peter DePaolo, 27, won the 1925 Indianapolis 500. At the Italian Grand Prix, he finished fifth in a works Alfa Romeo. He started as the riding mechanic for his uncle Ralph DePalma. By 1922 he became a driver with a Frontenac which he wrecked at the Indy 500. In 1923 he drove a Leach/Miller which he crashed at Fresno, California. In 1924 he finished sixth at the Indy 500 with a Duesenberg, came fourth at the Charlotte 250 Miles and ended up twelfth in the AAA Championship. 1925 was his best year winning the Indy 500 and the AAA Championship ahead of Tommy Milton.

Robert Marcel Charles Benoist, 30, Frenchman from St. Benoît near Paris, had left WW I in 1919 as a daring fighter pilot. He began racing in 1921 and was accepted into the Salmson racing team later that year. After some minor successes including an outright win at the 1922 Gaillon hill climb with an 8-cylinder Salmson, he was offered a drive with Delage in 1924. During his time with the team he came third in the 1924 French Grand Prix, fourth at San Sebastian and won the 1925 French Grand Prix with Divo and at the San Sebastian Grand Prix he finished second.


April 30, 1925 - Gerhard Ferdinand Kluge (D), 32, an accomplished independent Mercedes sports car driver, died after a short illness in his castle at Königswartha in Oberlausitz (D).

June 20, 1925 - André Guilbert (F), died in 1925 at the 24 Hours Le Mans as the result of a crash whilst driving on his way to the race during the morning of the race. He was driving his 2.5-liter Ravel 12 hp sports car, which was designed by the brother of the composer Maurice Ravel. His car was struck head-on by a van traveling at high speed on the wrong side of the road on the Mulsanne Straight. The van driver only suffered slight injuries, but Guilbert died a few hours later from his injuries, though another source claimed that he died on June 23.

June 20, 1925 - Marius Mestivier (F), driving an 1100 Amilcar CGS Grand Sport, died at the 24 Hours Le Mans race. At 8 pm, on his eighteenth lap, spun his Amilcar on the Mulsanne Straight, and the car swerved off the road and plunged head first into a ditch, killing him instantly. An early report claimed a blown tire or a locked brake caused the crash, but many sources later claimed that he was struck by a bird, causing him to lose consciousness.

June 20, 1925 - Paul Jessen (D) from Cologne died in a crash with another car during the sports car race of the Eifel-Rennen at Nideggen near Vlatten where his #76 Excelsior spun in a curve. Ludewig in the #118 Bugatti was following closely and drove at full speed into the side of the Excelsior that was blocking the curve. Jessen was immediately dead and his passenger was seriously injured. Ludewig who held a promising position in the race was also seriously injured.

July 19, 1925 - Flöhr (D), a riding mechanic, died at the Selbecke-Zurstraße hill climb near Hagen, Westphalia. He was leaning out while going through a turn, he lost his balance and his head hit a tree, causing his immediate death.

July 26, 1925 - Antonio Ascari (I) crashed on lap 23 while leading the French Grand Prix, driving an Alfa Romeo P2. The race officials received statements from André Boillot, who was present at the location of the accident on the Straight of Saint Eutrope. Ascari had clipped a post of the retaining wooden palisades with the hub of the left front wheel on a fast and long left-hand bend at a speed of about 180 km/h. The car then uprooted around 100 meters of the light fencing with the wheels now on soft earth, before it finally went out of control. The car spun around and made another half turn before it ran front first into the 1½ meter wide ditch where it overturned twice, flying high through the air. At the second time Ascari was ejected from his seat.
Boillot was the first to reach the scene and rushed to lift up the injured Ascari. With tears in his eyes Boillot reported that Ascari was fully conscious and even when he pulled the gloves from his hands with a broken arm. It took quite some time before medical help arrived for Ascari. Severely injured and bleeding from several head wounds, after an emergency dressing, he was lifted into the ambulance which brought him to the grandstand where Doctor Richard gave first aid. Ascari had a serious leg injury and a fracture of the right arm. Part of his back was sheared to the bone and much of his scalp, the size of a hand, was removed. By now Ascari was unconscious. Besides him his mechanic Giulio Ramponi cried like a child and made an effort to help the doctor in his office. There was nothing else to do than to take Ascari immediately to Paris. The ambulance left the grandstands in the midst of general consternation. Ascari died even before the town of Linas was reached, where the body of the unfortunate driver was brought to the Alfa Romeo headquarters in that town.

August 10, 1925 - Onesimo Marchisio (I) driving a 2-liter Diatto at the Cuneo-Colle della Maddalena (I) hill climb, was gravely injured on August 9. When he was in a curve 48 km from the start between Sambucco and Pietroporzio he lost control. The car went in a roadside ditch, and hit a pole where his riding mechanic Mario Maladora was thrown from the car, escaping with minor injuries. The car then rolled down an embankment with the driver inside who suffered severe chest injuries. There were no spectators at the scene and the car was not seen by passing cars. Rescuers only arrived after the end of the hill climb. A doctor assisted him in Pietraporzuio but he died of his injuries the following day.

August 30, 1925 - Paul Vauthier (F) was the riding mechanic in the 3-Liter Bignan of Henri Matthys (F) during the August 30 Boillot Cup race at Boulogne-sur-Mer. Trying to avoid a spectator who was crossing the road, Matthys lost control; the car hit a tree, overturned and caught fire. Both of the occupants were seriously injured. Vauthier died hours later, while Matthys died 15 days later on September 14 in the Boulogne-sur-Mer hospital.

September 12, 1925 - the date is not certain - Bodo Raddaz (D) died during practice for an event near Breslau, Germany, organized by the ADAC. He was thrown from his car while taking a bend and landed in such a way that he was immediately dead.

September 19, 1925 - Paul Torchy (F) died on lap five of the San Sebastian Grand Prix, driving a Delage 2LCV. The accident took place after 13 km at the Aurte bend, at the descent of Hernani. He was trying to pass Masetti's Sunbeam whom Torchy had been following closely. Torchy passed on the right, but ran off the road into the loose earth. The car went into a skid at full speed and crashed against a tree on the other side from which it bounced off and collided with another tree which it uprooted. The impact threw Torchy violently against the steering wheel, crushing his chest and he died seconds later.

Carlo Masetti wins the Royal Rome Grand Prix with Bugatti

by Hans Etzrodt
The Reale Premio Roma was the first international race of the season. Only eight of the 35 starters finished the 424 km race. After the first 5 laps Brilli Peri (4.9-L Ballot) led ahead of Materassi (5.8-L Itala Special), followed by Minozzi (3.6-L Alfa Romeo), Carlo Masetti (2-L Bugatti), Nardi (3-L Alfa Romeo) and Werner (2-L Mercedes). The battle for victory was amongst these six contenders while the remaining 29 drivers could only hope for a class victory. As the furious battle progressed, cars dropped out with breakdowns or driver errors. When Brilli Peri retired after six laps, Masetti took the lead and kept it unchallenged until the end, finishing three laps ahead of Materassi. Ginaldi (3-L Alfa Romeo) was third, ahead of Croce (1.5-L Bugatti), Platè (1.5-L Chiribiri), Mazzotti (1.5-L Bugatti), Nino" (1.5-L Chiribiri) and Clerici (1100 Salmson) the eighth and last finisher. The race officials stopped six cars which did not finish in the required time but were still running. The 21 retirements included Werner who crashed his Mercedes after he held second place. Likewise, the Minozzi/Ascari Alfa Romeo was eliminated when Ascari crashed with Maggi's Bugatti, eliminating both category leaders.
The Reale Premio Roma was held for the first time and was organized by the still young Automobile Club di Roma which decided to use existing roads to form the 10.6 km Monte Mario circuit just north of the Vatican where it went in clockwise direction along the twisting roads. The start was on Rome's longest straight, the Viale Angelico, heading south and soon turning sharp right into Viale Milizie with another right along Via Trionfale climbing along a narrow winding road up Monte Mario. From there the course wound through numerous half turns downhill along the Cammilluccia. After more right turns into Via Cassia there was a sudden descent through the most difficult right turn near the Milvio Bridge leading into Viale Angelico, where it snaked along the Tiber River through a left bend and a left-right onto the long straight towards the finish. An average speed of only 105 km/h was expected for even the fastest cars on a dry road because the turns were not cambered, often banked the wrong way, and the narrow road seldom exceeded six meters in width.
      The Reale Premio Roma had been planned for January 24 and 25 but had to be postponed to February 22 to 24 because of urgently needed road improvements. The entries were divided into five categories by capacity, I. up to 1100 cc, II. 1101 to 1500 cc, III. 1501 to 2000 cc, IV. 2001 to 3000 cc, V. over 3000 cc. The cars had to be occupied by either the driver and his mechanic, or just the driver, in which case the vehicle had to carry 70 kg of ballast. The maximum allowable time for each category was ½ hour after arrival of the first car. After the racecar event, the touring car race was held in two stages on the same circuit during the following two days.
      The overall winner, the driver who, regardless of class, completed the race in the shortest time, received 100,000 lire. In each of the categories the winner received 10,000 lire, second 6,000 and third 4,000. A reproduction of the Roman she-wolf was awarded to the manufacturer of the overall winning car.
An unusually large entry list of 42 cars comprised 5 in the 1100 category, 14 in the 1500 category, 10 in the 2000 cc category, 6 in the 3000 cc category and 7 in the category over 3-liters. 10 of the cars were Bugattis, 4 Diattos, 4 Alfa Romeos, 3 Italas or Specials, 4 OMs, 4 Chiribiris, 3 Mercedes, and 1 each Fast, Ballot, Aurea, Fiat and Bianchi, also 3 Salmsons and 2 Amilcars. With one exception, the drivers were all Italians but famous names like Campari, Bordino and Costantini were not in the entry list.
      The race had an international aspect with a German entry of Christian Werner with the same Mercedes in which he had won the 1924 Targa and Coppa Florio races, but it was not a works entry. He was accompanied by Alfred Neubauer, the officially nominated reserve driver, who had last raced four months earlier at the 1924 Italian Grand Prix. Both Germans raced with an Italian license by the ACI. Other officially entered reserve drivers were Bernardi for Ginaldi (Alfa Romeo); Giani for Ruggeri (Alfa Romeo); Ascari for Minozzi; Giulio Masetti for Bonmartini (Mercedes).
      There were four RLTF Alfa Romeos, all independent entries, although the 3.6-Liter car of Minozzi carried the famous clover leaf emblems on the hood. His riding mechanic was none other than Giulio Ramponi, a long time Alfa Romeo employee and leading mechanic. Evidently this car was a works entry in disguise, especially when considering that Minozzi's reserve driver was none other than Antonio Ascari, the number one driver at Alfa Romeo.
      Alfieri Maserati had entered his Diatto Special, which was powered by a 5.9-liter 4-cylinder Hispano-Suiza aero engine. Gazzetta dello Sport stated that Carlo Lecot, actually the Frenchman François Lecot, was the substitute for Maserati who was subject to a 2-year ban from racing. At the May 25, 1924 Rabassada hill climb Maserati had made the fastest time of the day, after which Pierre de Vizcaya filed a protest. It was then discovered that the engines of both Diatto cars had a larger capacity than had been quoted on the entry list. It was an accidental mistake but the Spanish AC disqualified the Italian company Diatto and Alfieri Maserati and banned them. Eventually, the ban was lifted at the 1925 February CSI meeting of the AIACR.
      The over 3000cc Category had two entries of 5.8-Liter Itala Specials for Materassi and Foroni. The cars had only a few Itala parts (clutch, gearbox, transmission) so to call them Itala 55 Specials, as was often done, is misleading. It had a makeshift chassis and suspension. It was called an Itala for publicity reasons as Materassi owned the Itala agency in Florence. The engine was half of a V8 Hispano-Suiza aircraft engine so the capacity was about 5.8 liters. The figure of precisely 4722cc, which is to be found in prevailing motor sport literature, is a mystery. This is well explained in an Alessandro Silva's article about Italian aero-engined specials, which was published in The Automobile magazine.
Wednesday practice was reported by the Gazzetta dello Sport. Brilli Peri, who was confident in his own ability and the road-holding of his car, did good practice times. According to rumors the fastest lap was performed by Minozzi with the Alfa Romeo in 6m38s. Bonmartini drove with a fur helmet that did not conceal his beard. Werner was not talkative and kept to a moderate pace. Nardi with his Alfa Romeo marveled at the safety of driving around the bends which often were banked the wrong way along the Camilluccia roadway. De Sterlich and Antonelli completed the circuit several times. Minoia with his two-liter OM was driving the turns of Monte Mario in perfect style. The wet road and the excessive heat betrayed De Grandis in the Fast when he slipped in the turn of Viale delle Milizie, knocking down a fence but without further damage. The Diatto of Ranza ended up in a field where he was temporarily stuck. On a later practice day Bonmartini crashed his 1924 2.0-L Targa Florio Mercedes and was unable to start.
The Non- starters included Meregalli (Diatto), Bonmartini (Mercedes), De Sterlich (Bugatti), Baccoli (Bugatti), Viarana (Bugatti) and Tartaglia (Amilcar). When Ciancherotti (1500 OM) was disqualified at the start for unbecoming behavior (details about this incident could not be found), the field was reduced to 35 cars. Rosa replaced Minoia in the #14 OM. The cars of Category V, over 3001 cc, were to start first and the field lined up as follows:

Shortly before 10:00 AM, Princess Mafalda left the Royal stand and went down to the track accompanied by both, the Representative and President of the Rome AC, Dr. Romeo Gallenga, Mr. Leonardi and a woman timekeeper. The Princess raised a flag in the colors of the Automobile Club. The six racecars of category five were vibrating, with their drivers eager to commence. At 10:00 AM the Princess Mafalda gave the starting signal by lowering the flag and Brilli Peri in his 4.8-L Ballot shot to the front. Next, the six cars of category IV, 2001 - 3000 cc, lined up and were started one minute later by the Princess.

Werner's Mercedes took the immediate lead and was still first in his class as he reached the top of Monte Mario. But on the decent he was passed by Carlo Masetti's Bugatti. The 1500 cars followed with an interval of one minute, showing here just the first two rows of this category, as seen in a photograph.
Pole Position












The 1100 cars followed with an interval of one minute. Soon after the start of the last cars Brilli Peri appeared in first place with a lap time of 6m53.2s. He was closely followed by Materassi and Minozzi. Nardi was leading the fourth category with a short gap to Ginaldi. In the third category Masetti in the fast Bugatti held the lead ahead of Werner's Mercedes. Count Maggi was leading the second category and the 1100 cars were initially led by Lancellotti.
      After the second lap Minozzi's Alfa Romeo showed traces of a dog which had been victim to the car's speed. Ruggeri (Alfa Romeo) retired after the third lap and Silitti (Bianchi) ended his race one lap later. Masetti passed Ginaldi and was amongst the fifth category cars. After the third lap one cylinder of Cesaroni's Mercedes was no longer working. De Vitis in the 4-cylinder Itala Spl., drove along with just two working cylinders, and in this condition he completed six laps before ending his race. Foroni retired on lap five. Cesaroni changed plugs on his Mercedes on the open road and again at his pit. After the fifth lap he had dropped to 23rd place and was then one lap behind with no chance of success. After the retirements of Ruggeri, Silitti and Foroni the field was down to 32 cars. Brilli Peri's average lap time for the first five laps was 6m51s with the field in the following order:
1.Brilli Peri (Ballot)   34m13sover 3000 cc category

After the sixth lap Brilli Peri retired on the circuit at Villa Colomba with a broken gearbox but other reports claimed that it was due to the differential. Minozzi, who was in second position after five laps stopped after the sixth lap at the pits to change a tire. Ascari, his official reserve driver, climbed into the car amid applause from the crowd. The reason for this driver change was not apparent but the pit stop dropped the well placed Alfa many places behind. While the crowd was still applauding, Masetti, Nardi, Werner, Materassi and Antonelli passed the parked Alfa Romeo and Ascari joined the race in sixth position. On lap eight De Vitis retired his Itala Special with engine failure. Spinozzi and Lancellotti retired on the ninth and tenth lap respectively, the latter with a broken gearbox. Maserati had dropped from tenth to 13th place. Brilli Peri, De Vitis, Spinozzi and Lancellotti had retired. The latter was no longer listed by the timekeepers while Vallecoccia (Amilcar) was shown 7 laps behind. As a result, the field was down to 27 cars. Werner allegedly had changed plugs on his Mercedes four times but still held third place. Masetti's average lap time for the last 5 laps was 6m45s. The order was as follows after ten laps:
1.C. Masetti (Bugatti)1h08m16s2000 cc category
2.Nardi (Alfa Romeo)1h09m36s3000 cc
3.Werner (Mercedes)1h10m16s2000 cc

After the 12th lap Cesaroni retired his Mercedes. It appeared that the fuel mixture had affected the spark plugs, possibly having used too little Benzene. Negro (Chiribiri) and Tattini (Fiat) probably retired after ten laps when they were two and three laps behind respectively and thereafter were not listed by the timekeepers. Ranza (Diatto) and Nardi (Alfa Romeo) also retired after the 13th and 14th lap respectively and consequently there were only 22 drivers left after 15 laps. Maggi fell several places behind and Serboli dropped several laps. Ascari was finally able to pass Materassi and Antonelli to gain third place. Masetti's average lap time for the last 5 laps had decreased to 6m36s when the order was as follows after 15 laps:
1.C. Masetti (Bugatti)1h41m16s2000 cc category
2.Werner (Mercedes)1h43m35s2000 cc
3.Minozzi/Ascari (Alfa Romeo)1h46m51sover 3000 cc

The number of participants was further reduced when Serboli retired his Chiribiri on the 11th lap. After the 18th lap Werner passed the grandstand with a dented hood, the result of an impact at the turn to Viale Milizie. He had made contact with the outer board fence after he had been signaled by his pit to increase his speed to pass Masetti. Far from narrowing the gap to Masetti, this incident increased it. On the 20th lap Antonelli retired for unknown reasons. Masetti's average lap time for the last 5 laps had decreased to 6m31s with the field down to 20 cars by lap 20:
1.C. Masetti (Bugatti)2h13m52s2000 cc category
2.Werner (Mercedes)2h19m47s2000 cc
3.Materassi (Itala Special)2h25m52sover 3000 cc1 lap behind

Morandi's OM was no longer shown by the timekeepers. After twenty laps he had been in sixth place one lap behind in the fastest OM but since then he had possibly retired. After lap 21, Werner stopped at his pit, changed plugs and refueled. He re-started but did not pass the pits again because he crashed for the second time. He escaped unhurt but the damage to his Mercedes was such that he had to leave the car at the curves of Monte Mario. Soon afterwards he was seen at the Mercedes pit. With the disappearance of Werner's Mercedes, Materassi took second place and Ascari was third in Minozzi's Alfa Romeo. On the 23rd lap Ginaldi stopped his Alfa Romeo to change a tire, and Mazzotti and Nino refueled. Lecot had engine problems and stopped frequently at the pits. De Grandis with the Fast was disqualified because he did not give way to others and the commissioners withdrew him from the race. On lap 20 De Grandis had completed only 13 laps, thus he is shown in the results with 13 laps or more completed. Maggi was no longer shown by the timekeepers. At 20 laps he was 3 laps behind and on lap 25 he would have covered 22 laps at best. On the 25th lap Maserati stopped at the pits for refueling. Materassi was once again firmly in second place. Clerici completed his regular pit stop and departed still in the leading position in the 1100 Category. Masetti had not yet stopped at his pit and had lapped the entire field at least once. His average lap time for the last 5 laps had decreased further to 6m25s. The field was down to 16 cars in the following order after 25 laps:
1.C. Masetti (Bugatti)2h45m57s2000 cc category
2.Materassi (Itala Special)2h57m47sover 3000 cc1 lap behind

On his 26th lap Ascari came at full speed along Via Cassia to the steep descent at Milvio Bridge and was about to lap the slower Bugatti of Maggi who was on his 23rd lap. Maggi was violently hit by Ascari, and the two cars entangled their wheels, continuing for about 100 meters until they reached the bend after the descent that precedes the Milvio Bridge. Unable to control their cars, they felled two telegraph poles, and both overturned. The drivers were flung from their cars, as were their mechanics. They escaped injury, except Maggi's mechanic, Angelo Rossi, who broke a chin bone. Count Maggi, the involuntary victim of the incident, walked back to his pit. As a result, the two drivers who could have won their respective categories disappeared from the race.
      Tassara passed the pits in second position after Maggi's retirement. After 30 laps Masetti in first place had a time of 3h18.6s. He was followed by Lecot (Diatto) in second place in 3h38m and Materassi in third place 3h39m56s but was three laps behind. After lap 33 the 1500 category leader Tassara, who was three laps behind, retired his Bugatti on the circuit. Croce then took the lead in this category. Pigazzi (Salmson) was far behind and was no longer shown by the timekeepers. At the end of the race the officials stopped him with the other stragglers.
      After 35 laps the field was down to 13 cars. Masetti who had gradually speeded up during the race again improved his average lap time for the last 10 laps to 6m22.1s. The times after 35 laps were:
1.C. Masetti (Bugatti)3h49m38s2000 cc category
2.Materassi (Itala Special)4h14m53sover 3000 cc3 laps behind

The race was coming to an end and the positions remained unchanged. At 2.15 pm King Vittorio Emanuele and Queen Elena arrived to witness the penultimate lap. They were accompanied by the Crown Prince and the Princesses Mafalda and Giovanna. The notes of the Royal March were played. The Crown Prince and the Princesses took their seats in the Royal stand, while Carlo Masetti crossed the finish line as the winner. After 4h21m29.6s at an average speed of 97.287 km/h, he received lively applause. Masetti's average lap time for the last 5 laps was 6m22.1s. He had not stopped during the race and was more than 4 laps ahead of Materassi in second place.
      The victor was summoned by the King to the Royal stand. Public applause greeted Count Carlo Masetti as he received congratulations from the Queen, the Prince and the King who presented him with a gold medal after which the Royal entourage soon left the circuit.
      From the remaining six finishers, Clerici (1100 Salmson) who was in eighth place finished the race 1h17m17.6s after the winner. The race ended ½ hour after arrival of the first in each category. For this reason the following stragglers were stopped by the officials and were not classified: Lecot, Balestrero, Maserati, Renzi and Pigazzi, all of whom would have been technically able to carry on racing.

In retrospect:
Ascari blamed Materassi for blocking him and filed a protest after the race. Materassi raced in the same category and won with his Itala Special. He had blocked Ascari for six laps and had not allowed room for Ascari's Alfa Romeo to pass. Ascari referred to the level roads where he could not pass him since his car was set up for rain with a lower final ratio and had always followed him a few seconds behind. He claimed that he could have easily passed his opponent on the hills. The Rome AC Sporting Commission approved the complaint and proposed to the ACI Sporting Commission that there should be a punishment for Materassi.

Masetti's speed with the winning Bugatti was beyond comprehension. His average lap time, calculated from the intermediate times, decreased continuously. After ten laps his average was 6m45s, then 6m36s, 6m31s, 6m25s, 6m22.1s and in the last 5 laps his lap average remained at 6m22.1s. While the other drivers were in slower cars or were hindered by car ailments or simply retired, Masetti continued driving at a furious pace. He did not let up but went ever faster until the very end, all the time passing slower cars, never stopped, and put every other driver at least three laps down. This is beyond comprehension why he put the car and a potential win at risk, when a slower pace would have been a more intelligent strategy.

Segrave wins the Provence Grand Prix and Hartford Cup

by Hans Etzrodt
The 1925 Grand Prix de Provence attracted an entry of 41 cars which were divided into 5 categories. From the opening lap the race was a Talbot-Bugatti duel, in which the 1500 Talbots of Segrave and Conelli gained the upper hand. Duller, in a third Talbot, also held the lead at one stage, as did Kidston with a 2000 Bugatti while Vidal in a similar car was second on some laps. After nearly four hours the Talbots of Segrave and Conelli finished ahead of Vidal's Bugatti, Duller's Talbot and Kidston's Bugatti. There were eight other further finishers, the best of which was Massias' 3000 Alfa Romeo, which was 44 minutes and 15 laps behind the winner. The two 1100 Salmsons of Didier and Bac deserve special praise as the only finishers in the 1100 class having completed the full race distance of 505 km.
The AC de Marseille used the Miramas circuit as its venue. Situated north-west of the large seaport of Marseille, it was located just a few kilometers north of the town of Miramas. The race track had been built at great expense for the 1924 Provence Grand Prix but instead some rather minor races were held that year.
      The flat 5.000 km oval track easily allowed speeds of up to 200 km/h. The wide corners were flat and only one was slightly banked but the rough concrete surface was hard on tires. The 1925 Grand Prix de Provence was the first running of the event. As a special feature for this race, at the end of the finishing straight there was a V-shaped serpentine turn, which increased the length of the lap from 5.000 km to 5.050 km. Cars arrived at this turn at top speed and had to brake hard and change gears. The Grand Prix was originally planned for 500 km, but it was increased to 505 km due to the addition of the 50-meter serpentine turn. The organization of the race left a great deal to be desired. There was only one access road on which everything moved under life threatening situations. Instead of stands there were only simple steps with boards on them, though there was one small grandstand near the Start and Finish line. There was no timing display and the timekeeping was less than accurate.
      The trophy offered by the Hartford Company (the well-known manufacturer of friction shock absorbers) was a superb objet d'art. It became the permanent property of the manufacturer who won it twice (whether consecutively or not). The trophy was entrusted during the year to the manufacturer who had last won it, but it had to be returned to the Society of the Autodrome in the first days of the following year. In the event that this trophy was won by an amateur, it was the manufacturer of his car that would be the holder. The Grand Prix de Provence was also richly endowed with 80,000 francs in prize money.
The Marseille AC received 41 entries, divided into 5 categories as shown at the beginning of this report.
1st category 1100cc: Salmson 2; Amilcar 1; Majola 1; Pelletier 1; Laisne 1, total of 6 cars.
2nd category 1500cc: Rally 1; Bugatti 6; Corre La Licorne 1; Talbot 3; Mathis 1; Chiribiri 2, total of 14 cars.
3rd category 2000cc: Bugatti 5; Ansaldo 2; Bignan 3; Diatto 1; Rolland-Pilain 2; Delage 1, total of 14 cars.
4th category 3000cc: Alfa Romeo 1; Fast 1; Turcat-Méry 3, Ariès, total of 6 cars.
5th category 4000cc: Voisin 1.
The 1500 Talbots were the same cars that had run at the 200-miles race at Brooklands in 1924.
      Michael Müller provided information about the Mathis of Francois de Brémond. It was a type RRC, 4 cylinders 69 x 100 mm = 1495 cc, abt. 50 hp (u/s). This model was the successor of the type RRB, same engine dimensions, which first appeared in 1921 as voiturette.
      Alex Nickerson informed us the Eftée stood for the initials F. T. or Frédéric Thelusson, who was quite active in French sports car racing in the 1920s. "Casellini" was the driver Fernand Casellini and small-time auto manufacturer Jean Majola, both were racing partners, including racing a rebodied Majola F in the 1925 24 Heures du Mans.
Only 28 drivers appeared for the race. They lined up in their cars on the track about 1500 meters before the start line where they received precise instructions from Mr. Walthausen of the Hartford Company. Mr. Rousset, President of the Marseille AC was in the large Hispano of Sadi-Lecointe, which served as the pilot car. Then François Repusseau, the major financial contributor of the Hartford Trophy, approached the finish line to fulfil his starter duties. He lowered his starting flag, at 10:45 AM and the race began. Immediately it was a fight between the 2-liter Bugattis and the 1500 Talbots.
      After the first lap, the Talbot of Segrave was in the lead by a hundred meters from Kidston's Bugatti, which was followed by Vidal, Duller, de Brémond and Conelli. The main obstacle of the circuit was the sharp V-shaped serpentine bend after the finish line. It consisted of three hairpins and required powerful and safe braking.
      The 1500 Bugattis of Savon and Dufour retired during the first ten laps, as did the Bignan of Martin and de Marguenat's Rolland-Pilain. This reduced the field to 24 cars after 50.5 km. The fastest lap was made by Kidston in a 2000 Bugatti in 2m14s at 135.669 km/h and his average lap time was 2m19s for the first 10 laps. At the end of ten laps Kidston led Segrave by 10 seconds with the third car of Duller over one minute behind when the field was in the following order:
1.Kidston (Bugatti)23m10s2000 cc category
2.Segrave (Talbot)23m20s1500 cc
3.Duller (Talbot)24m16s1500 cc

At the end of 20 laps Kidston still held the lead now 45 seconds to Segrave with Duller over two minutes behind in third place. Conelli, Massias and Vidal followed next. Kidston's average lap time for the last 10 laps was 2m8.8s. Between laps 10 and 20 the 1500 Bugatti of Lehoux retired, as did the 1100 cc Majola of Casellini (though the Majola firm later claimed that Casellini completed 78 laps) and the 1100 cc Lalane of Boisson, leaving only 21 cars after 101 km. On the twentieth lap the timekeepers gave a similar race order to the one ten laps earlier. The famous French sports journalist Paul Meyan claimed that he could see that the three Talbots were in the lead, and the official order was therefore wrong in his opinion. It was a failure of human timing that prevented the timekeepers producing the correct order. Paul Meyan suspected that some of the times up to lap 30 may have been flawed but as of lap 40 they were ok but he provided no other details. These were the only official times published in L'Auto. Paul Meyan attributed the spectators' boredom to the lack of exact information from the timekeepers and a display that was somewhat primitive. The 21-car field was in the following order after 20 laps:
1.Kidston (Bugatti)   45m38s2000 cc category
2.Segrave (Talbot)   46m23s1500 cc

Conelli moved from fourth position and was the new leader, having overtaken Duller, Segrave and Kidston. Kidston, the race leader for the first 20 or more laps had now dropped to fifth, having been overtaken by Conelli, Segrave, Vidal and Duller. At the end of 30 laps Conelli was leading Segrave by 63 seconds with Vidal over two minutes behind in third place followed after 8 seconds by Duller. Kidston must have experienced some sort of a problem because he dropped from the lead two laps behind. The 1100 category was still led by Didier ahead of Bac and Orello. Conelli's average lap time for the last 10 laps was 2m21.5s. When Gubernatis in the 2000 Bignan retired between lap 20 and 30, the field was down to 20 cars after 151.5 km. According to Paul Meyan, on the 35th lap it was easy thanks to scores made outside the timer's stand to restore the regular order of classification. The 20-car field was in the following order after 30 laps:
1.Conelli (Talbot)1h11m47s1500 cc category
2.Segrave (Talbot)1h11m50s1500 cc
3.Vidal (Bugatti)1h13m59s2000 cc
