The 1984 Brazilian Grand Prix, officially known as the XIII Grande Prêmio Brasil de Fórmula 1 was a Formula One motor race held on 25 March 1984 in Rio de Janeiro. The race was contested over 61 laps of Jacarepaguá Circuit and was the first race of the 1984 Formula One World Championship. This race was the 13th edition of the Brazilian Grand Prix, the ninth time that the Jacarepaguá Circuit race held a Grand Prix, and marked the debut of Ayrton Senna in Formula One. In qualifying, Italian driver, Elio de Angelis from Team Lotus claimed pole for the second time in his career as he finished ahead of fellow Italian driver, Michele Alboreto who was in the Ferrari. In the race it was Alain Prost in the McLaren car who would take out his second win in Brazil. He finished ahead of Keke Rosberg who was in the Williams with de Angelis finishing in third. Qualifying Elio de Angelis claimed the first pole position of the season in his Lotus-Renault from the Ferrari of Michele Alboreto in his first race for the Prancing Horse. Derek Warwick, in his first race for Renault, was 3rd on the grid with the McLaren-TAG of Alain Prost 4th, Prost returning to the team he started his career with after three seasons with Renault. Reigning World Champion (and local favourite) Nelson Piquet qualified 7th in his Brabham-BMW, while another Brazilian, a Formula One rookie by the name of Ayrton Senna qualified 17th for his first ever Grand Prix in his Toleman-Hart. Race With only 220 litres of fuel allowed, many teams on the grid tried various ways to save fuel from evaporating in the Rio heat. McLaren covered their cars in tin foil while others such as Lotus and Renault attempted to freeze their fuel in order to actually fit more in. The Renault team also had a sophisticated (for 1984) electronic fuel monitoring system which they hoped would give them an advantage over their rivals. Alboreto got the jump at the start and led early from Warwick and de Angelis, with the McLarens of Niki Lauda 4th and Prost fighting back from a bad start. The Frenchman had bogged down at the green light with too few revs and was only 10th at the end of the first lap (Piquet also made a bad start after almost stalling at the green light
