1923 French Grand Prix: Epilogue

September 19, 2012 By pete

Did the daring new designs by Voisin and Bugatti advance the art of race car engineering? Read Gijsbert-Paul Berk’s surprising analysis. (Above, Alfas at Lyon, 1924.)

By Gijsbert-Paul Berk

When the dust had finally settled down and the excitement of the race was ebbing away, many of the French spectators went home somewhat disillusioned. The expected duel between the Bugatti and Voisin cars never happened. It was obvious from the beginning that the six-cylinder sleeve valves of the Voisin “Laboratoires” were no match for the more powerful eight cylinders of the Bugatti Tanks. The new V12 Delage had retired within a few laps from the start, and after a valiant struggle the two Tours-based Rolland-Pilains were also forced to retire with mechanical problems.

No, it had not been a glorious day for the French manufacturers. In spite of the fact that a Bugatti and a Voisin had finished in third and fifth place, the foreigners in their Fiats and Sunbeams had dominated this Grand Prix de France from the first lap onward.

And even more importantly, did the outcome of this battle between conventional Grand Prix cars and the revolutionary and daring new designs from Bugatti and Voisin have much of an influence on the future of Grand Prix racing?

The sad truth is that from an engineering point of view, it set the clock back.

The 1924 contenders: Improved engines, horsecart chassis, minimal streamlining.

Louis-Coatalen

Louis Coatalen, Sunbeam's chief engineer.

Established in 1899 and based in Wolverhampton UK, Sunbeam was known for its sturdy but unexciting line of cars. Things changed in 1909 when Louis Hervé Coatalen (1879 -1962) became chief engineer. [Read more…] about 1923 Grand Prix of Tours Part 5: Sunbeam and Voisin

1923 French Grand Prix Part 1: The Circuit and Practice

July 25, 2012 By pete

By Gijsbert-Paul Berk

The circuit was a closed-off triangle of public roads, just north of the city of Tours. The starting line was situated just outside a small borough called La Noue-Guérinet, between the villages Neuillé-Pont-Pierre and La Membrolle on the Route Nationale 158. The numbers on the map above correspond to the photographs below. The 1923 Grand Prix of Tours was much tougher and much longer than today’s Grand Prix events. In order to finish, the participants had to cover a distance of 800 km (497 miles). As the ‘Circuit de la Touraine’ had a total length of 22.83 km, (14.1 miles) this meant 35 grueling laps. On the straights some of the cars reached speeds of nearly 200 km/h (125 mph). Around the circuit. 22 marshaling posts had been installed each of them equipped with a telephone in direct and permanent contact with the officials at race control in front of the grandstand.

Come with us as we take a lap around the 1923 French Grand Prix.
