Sunday 25th March 1984

Ayrton Senna made his Formula One debut at Jacarepagua, Brazil, racing for Toleman Motorsport. It was the first round of the 1984 Formula One season and the first race where the FISA mandated 220 litre fuel limit came into effect, with the re-fueling of 1983 now banned. Many of the drivers correctly predicted that this would turn Grand Prix racing into fuel economy runs rather than actual races. Alain Prost won the race in a McLaren MP4/2-TAG.
