1951 World Championship of Drivers

The 1951 Formula One season was the fifth season of FIA Formula One motor racing. It featured the 1951 World Championship of Drivers, which commenced on 27 May 1951 and ended on 28 October after eight races. The season also included 14 races that were open to Formula One cars but did not count towards the championship standings.

Ferrari's newer, unsupercharged 4.5 litre cars offered a real challenge to the Alfas, which were nearing the end of their development potential. The Ferraris were able to capitalize on the inefficiency of the Alfa's very thirsty engines, particularly at Silverstone. Although Alfas won four races, with Fangio taking the championship, Ferrari's three victories spelled the end for the Alfas. BRM made their only championship appearance with the V16 at Silverstone, and the old, slow Talbots were increasingly outclassed.

Points were given to top 5 finishers (8, 6, 4, 3, 2). 1 point was given for fastest lap. Only the best four of eight scores counted towards the world championship. Points for shared drives were divided equally between the drivers, regardless of who had driven more laps.

The Formula One Championship season started in Switzerland at the very dangerous and tree-lined Bremgarten public road circuit near Bern around the time the Monaco Grand Prix would have been held- but that historic race was not held this year. Alfa Romeo, the dominant team in 1950 with its supercharged 159 Alfetta, took the first 5 places on the grid, with the exception of 3rd, which was taken by Luigi Villoresi in a Ferrari. Argentine Juan Manuel Fangio was on pole position, with his Italian teammate Giuseppe "Nino" Farina alongside him. The race started while it was raining, and with its overhanging trees lining the road, this circuit was even more dangerous in the wet. But Fangio made no mistake and won the race from Piero Taruffi in a Ferrari and Farina, whose decision to run the race without changing tires proved to be the wrong decision.

The Indianapolis 500 in the United States was run 3 days after the Swiss Grand Prix on a Wednesday, and was the only non-European championship round and the only round not run to FIA Grand Prix regulations. Lee Wallard won this demanding race in his Kurtis Kraft-Offenhauser.

The next Grand Prix was in Belgium at the very fast and spectacular 8.7 mi (14.1 km) Spa-Francorchamps circuit. With Fangio and Farina once again 1-2 with the Ferraris of Villoresi and Alberto Ascari taking 3rd and 4th, the Alfas and Ferraris dueled around this circuit, with only 13 entries- small grids in all kinds of motorsports in Europe were commonplace at Spa, because of the fear most drivers had of the circuit. Farina won by 3 minutes over Ascari and Villoresi, with Fangio finishing 4 laps down in 9th after one of his Alfa's wheels jammed on its hub.
