1975 Italian Grand Prix

The 1975 Italian Grand Prix was a Formula One motor race held at Monza on 7 September 1975. It was race 13 of 14 in both the 1975 World Championship of Drivers and the 1975 International Cup for Formula One Manufacturers. It was the 45th Italian Grand Prix and the 41st to be held at Monza. The race held over 52 laps of the five kilometre circuit for a race distance of 300 kilometres.

The race was won by Swiss driver Clay Regazzoni in his Ferrari 312T in a glorious day for Scuderia Ferrari. It was Regazzoni's third win, Ferrari's fifth win for the season. Regazzoni took a sixteen-second win over the McLaren M23 of outgoing world champion, Brazilian driver Emerson Fittipaldi. Behind Fittipaldi was the second Ferrari of Austrian driver Niki Lauda who secured enough points to win his first out of three world championships.

Arturo Merzario was driving the Fittipaldi, replacing Wilson Fittipaldi was still recovering from his crash at the Austrian Grand Prix.

The Italian supporters were gathered in expectation of Ferrari gaining their first championship in 11 years-on home ground, with many Austrians travelling over the border to support Niki Lauda and were delighted when Ferrari filled both spaces on the front row. Tony Brise delighted his boss Graham Hill by gaining a third-row spot.

Lauda only needed to finish better than 6th to be champion; The only other driver who was mathematically eligible for the championship, Argentine Carlos Reutemann needed to win this race as well as the United States Grand Prix with Lauda out of the points in both races.

On Sunday morning there was a cloudburst and for some time the future of the race was in jeopardy, but the rain dried up with about an hour to go before the start. Clay Regazzoni led from Lauda and Jody Scheckter.

Vittorio Brambilla's clutch burnt out on the first lap, whilst Bob Evans halted with a failed engine plug. There was a chaotic accident at the chicane-Scheckter had to take to the escape road as around him Jochen Mass hit the kerb, damaging his car's suspension. Ronnie Peterson collided with another car, jamming his throttle open. Mario Andretti and Rolf Stommelen retired with accident damage and Brise spun across the chicane. Harald Ertl soared over the top of Hans-Joachim Stuck's car, damaging the uprights.
