Alfa Romeo took their third front row lockout of the season at the Belgian Grand Prix at the speedy 8.7 miles (14.0 km) Spa-Francorchamps circuit, while the Ferrari of Villoresi shared the second row with the privateer Talbot-Lago of Raymond Sommer. The Alfas were once again untouchable at the start of the race, but when they stopped for fuel, Sommer emerged as an unlikely race leader. His lead, however, was short-lived, and he was forced to retire when his engine blew up. Fangio ultimately took the victory, ahead of Fagioli, who again finished second. Rosier again made the podium in his Talbot-Lago. He had been able to pass the polesitter Farina when the Italian picked up transmission problems towards the end of the race. It was not all bad for Farina, however, as he picked up the point for fastest lap. Fagioli and Fangio closed the gap to Farina in the points standings—Fagioli was just four points adrift, while Fangio was a further point behind.
