Juan Manuel Fangio closed the 1955 season with victory in the Italian Grand Prix, leading Taruffi home for Mercedes. Monza‘s newly combined road-and-banking circuit demanded major technical adjustments, and tyre concerns prevented Ferrari‘s newly acquired Lancias from starting.

Championship background
Juan Manuel Fangio arrived at round 7 leading the 1955 F1 World Championship on 33 points, with Stirling Moss on 22.
Race entries
Ferrari entered the Lancia D50s it had taken over as well as its own Super Squalo cars. Mercedes brought both streamlined and open-wheel machinery, and Maserati tried a streamlined 250F. Vanwall and Gordini also attended, with the new eight-cylinder Gordini making its championship appearance.
Thursday banking familiarisation
The opening period was restricted to the banking so drivers could learn its unusual demands. Farina survived a high-speed tyre failure, while many cars grounded over the bumps and needed suspension changes. Mercedes decided longer chassis handled better and arranged an urgent delivery from Stuttgart. The session exposed serious tyre and durability concerns before full-circuit qualifying began.
Friday timed practice
The complete ten-kilometre circuit opened for grid-setting laps. Fangio led the way, with Kling also quick and the Lancias showing strong pace. Moss waited for a preferred long-chassis car. Maserati evaluated its streamlined bodywork, while Mercedes experimented further with nose shapes to improve stability on the banking.
Saturday final qualifying
Heavy morning rain led to an afternoon extension. Moss’s replacement car had arrived and he improved, but Fangio’s earlier time secured pole. Vanwall adopted larger wheels to reduce tyre risk. Another warning sign on Farina’s tyre reinforced Ferrari‘s concern, and the Lancias were ultimately withdrawn; Castellotti switched to a Super Squalo for the race.
Qualifying Classification
Thursday’s banking-only running was familiarisation. Friday and Saturday laps on the full combined circuit established the grid. Castellotti retained a starting place after changing from the withdrawn Lancia to Ferrari machinery.

What happened in the 1955 Italian Grand Prix?
Mercedes established control immediately, with Castellotti working hard to stay close. The banking and sustained speeds steadily exposed weaknesses elsewhere in the field. Moss and Kling eventually retired, leaving Fangio and Taruffi to complete the team’s challenge.
Fangio remained ahead, while Castellotti brought Ferrari home third. Behra finished fourth and Mieres fifth for Maserati. Moss retained the fastest-lap point despite his retirement, but could not add another victory to his Aintree success.
Fangio had already secured the championship after the cancellation of other rounds. Monza supplied a winning finale before Mercedes withdrew from Grand Prix racing, ending a dominant two-season campaign. The new circuit layout had produced an imposing spectacle and substantial engineering concerns.
After the race, Juan Manuel Fangio headed the drivers’ standings with 40 points, followed by Stirling Moss on 23.
