The 1957 Monaco Grand Prix was a Formula One motor race held on 19 May 1957 at Monaco. It was race 2 of 8 in the 1957 World Championship of Drivers.
Despite a hesitant start, Moss led away on the first lap from Collins, Fangio, and Hawthorn. On lap 4 coming out of the tunnel, there was mayhem. Moss went straight through the chicane, sending debris from the wrecked barrier crashing onto the circuit. Collins crashed through the quayside barriers trying to avoid it. Fangio and Brooks slowed to make their way through the carnage. Brooks' effort was for nought, being hit by Mike Hawthorn's Ferrari, which lost a wheel. Fangio took the lead from Brooks' damaged car and held it to the chequered flag.
On lap 96, with nine laps to go, von Trips lost a certain third place when his engine blew up. Brabham inherited it, but he in turn lost the place when the engine in his Cooper T43-Climax cut out at Casino five laps from the end. He coasted to the harbour and pushed the car home for 6th place.
This race marked the Formula One World Championship debuts of Masten Gregory, Stuart Lewis-Evans, and Ivor Bueb. Gregory's third place was the first Formula One podium for an American driver (excluding Indianapolis 500 races).
It was also the debut World Championship podium for Vanwall as both a constructor and an engine supplier.
Lastly, it was also the debut race for the Coventry Climax engine, the 4-cylinder FPF, still undersized at 1,964 cc, and mounted in the Cooper T43 in Rear mid-engine, rear-wheel-drive layout similar to the Bugatti Type 251 at the 1956 French Grand Prix. It was also the first F1 finish for both Cooper and Climax even though Brabham pushed the car over the line.
