Pre-race

In the fortnight between the 1984 Dutch Grand Prix, Dutch and Italian Grands Prix, the FIA Court of Appeal upheld the exclusion of the Tyrrell Racing, Tyrrell team from the championship for alleged technical infringements, and the team were duly banned from the final three races of the season. The Italian Grand Prix would thus be the first all-Turbocharger, turbo Formula One race in history. Meanwhile, the Toleman team had suspended Ayrton Senna for not informing them of his signing for Team Lotus, Lotus for before the deal was announced at Zandvoort.

Race report

Manfred Winkelhock, who had qualified 21st in his ATS Wheels, ATS, suffered a gearbox failure on the formation lap for the second time in three races. Frustrated, he subsequently quit the team. At the start, de Angelis passed Prost and Piquet, though the Brabham driver retook the lead into the first chicane. Tambay also made a fast start to run fourth, while Lauda fell to seventh behind Mansell and Fabi. While Piquet set about building a lead, Prost and Tambay overtook de Angelis, only for Prost's engine to fail on the fourth lap. In the meantime, Fabi and Lauda passed both Lotuses, and were thus up to third and fourth. On lap 8, Fabi spun at the Roggia chicane, dropping to eighth; a charge put him back up to fourth by lap 12. By this point, Michele Alboreto in the Scuderia Ferrari, Ferrari had also passed both Lotuses and was now fifth. While this was going on, a high attrition rate was building: the second Ferrari of René Arnoux suffered a gearbox failure on lap 6, while the two Equipe Ligier, Ligiers of Andrea de Cesaris and François Hesnault dropped out on lap 8, followed shortly afterwards by the two Williams of Rosberg and Jacques Laffite. By lap 15 the two Lotuses had also retired, Mansell spinning off and de Angelis' gearbox failing. Piquet continued to lead from Tambay, both clear of Lauda. On lap 16, Piquet's engine failed; at around the same time Fabi, continuing his charge, overtook Lauda to run second. Fabi then started to catch up to Tambay and by half-distance was on the Renault's tail, with Lauda keeping close behind; all three were clear of Alboreto, with Derek Warwick in the second Renault up to fifth and Cheever sixth. On lap 32, Warwick suffered an oil pressure problem, moving Johansson into the top six. On lap 40, Lauda overtook Fabi at the Parabolica, before passing Tambay for the lead at the Roggia three laps later. Then, on lap 44, Fabi and Tambay suffered engine and throttle failures respectively. This left Lauda with a lead of 20 seconds over Alboreto, with Cheever up to third followed by Johansson, Patrese and the Osella of Piercarlo Ghinzani. On lap 46 Cheever ran out of fuel, followed three laps later by Ghinzani; meanwhile, Patrese passed Johansson for third. At the chequered flag, only Lauda and Alboreto were on the lead lap, with Patrese one lap behind Lauda and Johansson a further lap back. Completing the top six were Jo Gartner in the second Osella and Gerhard Berger in the second ATS, though neither driver would receive points as both their teams had officially entered only one car for the championship. The win, Lauda's fifth of the season, put him 10.5 points clear of Prost at the top of the Drivers' Championship with two races remaining. In the Constructors' Championship, Alboreto's result enabled Ferrari to move ahead of Lotus into second behind McLaren.

Race classification

* Neither Gartner nor Berger were eligible for points, as they were driving the respective "second entries" of Osella and ATS and both teams had officially entered only one car for the entire championship.
