1000 km of Paris
The 1000 Kilometres of Paris was an endurance race, mainly for sports cars, which was held at the Autodrome de Linas-Montlhéry in France from 1956 to 1995.

1956
The event is called Grand Prix of the Automobile Club of Île-de-France. Following the accident of the 24 Hours of Le Mans 1955  and the measures taken by the public authorities, the safety conditions of the Linas-Montlhéry autodrome were improved; in particular 34 stands, with access to refueling, were built. A Maserati 300S win at the average speed of 150.239 km/h. A Gordini T15S finished in eighth place, a  DB Panhard at the thirteenth, a Ferry powered by Renault at the fourteenth and a Vernet-Pairard — also powered by Renault — at the sixteenth. The three  Panhard Monopoles did not finish.

1962
The race became part of the World Sportscar Championship. René Bonnet and Charles Deutsch each line up a 1000 cm3 prototype powered by Renault and Panhard. The domination of the Ferrari 250 GTO was unchallenged in the first six places: Pedro and Ricardo Rodriguez win another victory at 157,727 km/h average.

1995
The race was interrupted after 540 km. The four Ferrari F40s entered in the Group GT1 were broken, as was the McLaren F1 GTR; only a Venturi 600 LM had saved the GT1's honor by finishing in fourth place.

Note: The 1972 race was held at Rouen-Les-Essarts.
