1955 Formula One season

The 1955 Formula One season was the ninth season of FIA Formula One motor racing. It featured the 1955 World Championship of Drivers, which commenced on 16 January 1955 and ended on September 11 after seven races. Juan Manuel Fangio won his second consecutive World Championship title in a season that was curtailed by tragedies.

The season also included a number of non-championship Formula One races.

Season summary
Mercedes drivers again dominated the championship, with Fangio taking four races, and his new teammate Stirling Moss the British Grand Prix. Ferrari won at Monaco after all of the Mercedes cars broke down and Lancia driver Alberto Ascari crashed into the harbour. Although Ascari was apparently unscathed, the double World Champion crashed fatally at Monza while testing sportscars four days later.

The disaster at the 24 Hours of Le Mans on 11 June which killed Pierre Levegh and over 80 spectators led to the cancellations of the French, German, Spanish and Swiss Grands Prix. The French round, which was supposed to be held at Reims between the Dutch and British rounds, on 3 July, was first rescheduled to 25 September and subsequently cancelled. Then the German event, scheduled for 31 July at the Nürburgring, the Swiss round at Bremgarten, planned to take place on 21 August, and the Spanish round, on 23 October at Pedralbes, followed suit. Pedralbes and Bremgarten were then abandoned and never used again for racing; motor racing was banned altogether in Switzerland and no motor-race was held in Switzerland until the 2018 Zürich ePrix. These cancellations effectively handed the Drivers' title to Fangio after he finished 2nd to Moss at the British Grand Prix; although he wasn't actually crowned champion until well after the British Grand Prix, because the German, Swiss and Spanish rounds were cancelled after the British Grand Prix took place.

1955 would be the final season for Mercedes Benz as a constructor until the team's revival in 2010. It would also mark the final win for Mercedes until the 2012 Chinese Grand Prix.

Aside from Ascari's death this year, Italian Mario Alborghetti died at the non-championship Pau Grand Prix in France driving a Maserati; and during the Indianapolis 500, two drivers were killed during the month-long event: Americans Manny Ayulo in practice and previous race winner Bill Vukovich during the race 2 weeks later.
