1951 French Grand Prix

It was race 4 of 8 in the 1951 World Championship of Drivers and was won by Juan Manuel Fangio and Luigi Fagioli driving an Alfa Romeo.

The race, which also carried the honorific title of European Grand Prix, saw the World Championship debuts of Aldo Gordini, André Simon and Onofre Marimón.

This race also holds the record for the longest Formula One Grand Prix in terms of total distance needed to cover.

Around this time, the gearbox in Ascari's Ferrari had broken, and he retired, although he took over the car of González, who had been pushing very hard.

Fuel stops and problems for the Ferraris enabled Fangio to make his way into the lead and win the race, with Ascari in González's original car finishing 2nd, 52 seconds behind.
