1983 saw Ferrari win again, with Patrick Tambay taking top honors and Riccardo Patrese crashing his Brabham hard at Acquaminerale while battling with Tambay for the lead. 1984 saw Prost win in a McLaren, and 1985 was yet another exciting race. Brazilian Ayrton Senna led much of the race; but Ferrari driver Stefan Johansson had started in 15th place, and was quickly making up places in only his second drive for the Prancing Horse; he passed Senna at the end of Lap 61 and took the lead. Unfortunately, Johansson had a fuel problem and retired; many others subsequently began to run out of fuel and Prost finished 1st only to be disqualified later when his car was weighed in as 2 kg underweight; victory was then handed to 2nd-placed Italian Elio de Angelis. 1986 saw Prost win yet again in a fuel-starved race. 1987 saw Senna take pole position narrowly from Briton Nigel Mansell; his teammate Nelson Piquet had a huge crash at Tamburello, and although he only received minor injuries, he did not participate in the race due to FIA doctor Sid Watkins declaring the Brazilian unfit for racing. 1988 saw the McLaren duo of Prost and Senna totally dominate; they were both three seconds faster in qualifying than the next-fastest qualifier Piquet in a Lotus.
