Sunday 26th August 1984
Alain Prost led home Niki Lauda for a MacLaren 1-2 at the Dutch Grand Prix. Nigel Mansell finished third in a Lotus-Renault. Before the race it was rumoured that Ayrton Senna would break a 3-year contract and leave the Toleman team at the end of the season to take up a 3-year contract with Lotus (the announcement was made 2 days after the race). This angered Toleman management as a clause in their contract with the Brazilian rookie stated that he had to inform them if he was leaving, something he did not do. As a result, Toleman suspended Senna from the next race in Italy. Also, with Jacques Laffite already known to be leaving Williams at the end of the season to return to Ligier, it was rumoured that team owner Frank Williams had signed Nigel Mansell for the 1985 season, a rumour that was ultimately proved correct.
McLaren-TAG won the Constructers’ Championship with 3 races left.
