The front row positions on the grid were shared equally between Alfa Romeo and Ferrari, with Fangio, Farina, Ascari and González posting the four fastest qualifying times. The second row consisted of the remaining works Ferraris of Villoresi and Taruffi, alongside Felice Bonetto. Reg Parnell, in a BRM, was also supposed to be on the second row, but was unable to start due to lubrication problems.
Fangio was the initial race leader, having started from pole position, but he soon had to cede the position to Ascari. He retook the lead on lap eight before pitting for a tyre change, which dropped him to fifth. Early retirements for Farina and de Graffenried left José Froilán González in second, behind his teammate Ascari. Fangio attempted to bridge the gap to the Ferraris, but engine problems eliminated his chances. The sole remaining Alfa driver, Nino Farina, who had taken over Bonetto's car on lap 30, inherited third place as a result of Fangio's retirement. He was fast, but fuel leakages meant that he needed to make two further pitstops; he therefore had to settle for third. Alberto Ascari took his second, and Ferrari's third, consecutive Championship race victory, ahead of British Grand Prix winner González. The other works Ferraris of Villoresi and Taruffi completed the points positions in what was another successful race for the Scuderia.[3]
Ascari's victory took him to within two points of Championship leader Fangio, while González was a further four points behind in third.
