Ecurie Rosier

Louis Rosier was the owner and manager of a famous racing team, the "Ecurie Rosier". It specialized in Talbot-Lago T26s, and later Maserati 4CLT and Maserati 250F, as well as Ferrari 500. This racing team allowed other drivers such as Henri Louveau, Georges Grignard, Louis Chiron, Maurice Trintignant, André Simon and Robert Manzon to find a competitive and well supported cars.

Circuit Louis Rosier

Louis Rosier was one of the key sponsors of the Charade Circuit. After WWII, Jean Auchatraire (president of the racing section of the local Automobile Club) and Louis Rosier promoted the idea of a race track around Clermont-Ferrand.

A set of preliminary designs were drawn up for a circuit of a length between 4 and 6 km, meeting the latest safety regulations with large parking capacity at a location just outside the city limits on a hilly landscape.

The 1955 Le Mans disaster (death toll: 135 lives) on 11 June 1955 brought the project to a halt. All race events were postponed. No further events were allowed to take place on temporary urban tracks. Racing events were only to be allowed on dedicated race-tracks, providing that they met a new set of rules. In Clermont-Ferrand, as was the case for many other new race tracks, new safety devices were being imagined and discussed, reviewed and assessed. But the concept of a "mountain race track" moved forward. It would be the only one of its kind in France.

Auchatraire, Rosier and Raymond Roche (the manager of Reims-Gueux race track) worked together to get the project accepted by the political community before searching for funding. But Rosier was killed at Montlhéry on 26 October 1956 and would not witness his project come to fruition. The racetrack was opened on 27 July 1958, with the name of its famous founder "Circuit de Charade Louis Rosier". Soon after, several champions participated in racing events on the track, each of them, including Stirling Moss, making very positive statements about the track and its surrounding.

Car manufacturer

Rosier's Renault dealership in Clermont-Ferrand was one of the largest Renault dealerships in France. Rosier's dealership also sold other industrial and farming equipment. The building housing this important business has been destroyed[10].

In 1951, Louis Rosier designed a prototype based on the 4CV Renault[11][12].

In 1953, using the concept of a barchetta that he raced at Le Mans[13], Rosier, together with Italian coachbuilder Rocco Motto, designed a cabriolet[14], still using 4CV Renault sub assemblies. This model was built in a quantity of about 200 units by Brissonneau[15]. It was even introduced at a car show in New York.

Some time later he designed a roadster using Renault Frégate elements with an aluminum body developed by Rocco Motto, on a multi-tubular frame. The engine was seriously revised, the body was lightened, the results was an interesting 950 kg for 80 hp[16].


Louis Rosier died of injuries he sustained in a crash at the Autodrome de Linas-Montlhéry track, south of Paris, France, on 7 October 1956.[17]
