The race saw future World Champion, Ayrton Senna make his debut. The Brazilian youngster qualified 16th but retired early on with a turbo failure. Also among the débutants was Martin Brundle who finished an impressive 5th in the Tyrrell-Ford. Brundle, however, was stripped of this finish when the Tyrrell team were disqualified from the championship for a technical infringement. Brundle's team-mate and fellow débutant, Stefan Bellof, failed to finish due to a throttle malfunction.
Kyalami was the original venue for the opening round of the 1984 season, however the race was moved to a later time in the championship to allow the race organisers to garner more sponsorship. The race was notable home territory for reigning world champion, Nelson Piquet however the Brazilian driver and his team Brabham-BMW had been suffering from reliability problems in pre-season testing, foreboding grim prospects for the race ahead.
Debuting in Rio was the reigning British Formula Three champion, Ayrton Senna who would be competing at his home event for his debut with the Toleman team. Alongside Senna to make their Formula One debuts was Senna's F3 championship rival Martin Brundle and Stefan Bellof of the Tyrrell team as well as François Hesnault of Ligier and Phillipe Alliot of RAM.
The full entry list for the 1984 Brazilian Grand Prix is shown below:
In qualifying, Piquet's reliability problems with his Brabham came to the foreground suffering an engine failure which saw him place only seventh on the grid. Ferrari, Renault, McLaren and Lotus battled for pole position in a thrilling session which went down to the wire. In the end it was Elio de Angelis of Lotus that took the pole time. Michele Alboreto's debut with the Ferrari team saw him line-up second ahead of Derek Warwick, his first race for the front running Renault team. Alain Prost's first race for McLaren in four years saw him line-up fourth ahead of Nigel Mansell and McLaren teammate Niki Lauda. Mansell being unable to equal De Angelis's time due to a spin into the gravel early in the Saturday session.
The Lotus's were quick but had faced stiff competition from Ferrari, Renault and McLaren. McLaren in particular had not showed their true hand, Lauda and Prost focussing on race set-up rather than grid position throughout practice.
The first grand prix of the season was set in extremely hot conditions, as a result there was expected to be many victims of mechanical failure in the race. On the formation lap Andrea de Cesaris's Ligier stalled, forcing the start to be delayed by an extra half an hour.
On the second formation lap, both the reigning champion Nelson Piquet and Johnny Cecotto's Arrows stalled. Rather than risk a further delay to the race, the Brazilian race organisers ordered the commencement of the race despite the stricken duo of Piquet and Cecotto. Piquet was able to get going with an assisting push from the marshalls and started from the back of the grid whilst Cecotto and De Cesaris made their starts from the pit-lane.
Taking the lead at the start was Michele Alboreto on his Ferrari debut, behind him De Angelis immediately began to suffer from a misfiring engine and dropped behind Derek Warwick, Nigel Mansell and Niki Lauda. Alain Prost had also made a poor start, his McLaren suffering from gearbox issues dropped down to tenth place. Stefan Bellof had got a flier of a start on his debut climbing from twenty second to fourteenth.
On the second lap, Lauda moved his way past Mansell and began to pressure Warwick's Renault ahead of him. Meanwhile the second McLaren of Prost began to make up for his poor start and began to move through the field, getting past Arnoux, Rosberg and Tambay in the following laps. Ayrton Senna's Toleman became the first retirement of 1984 when he pulled out with boost issues on lap 9.
The following lap, Warwick who had been holding Lauda up for a number of laps was shoved out of the way by the McLaren driver who moved into second behind Alboreto who continued to lead convincingly at the front. Whilst maintaining a lead, the Ferrari driver had been suffering from brake troubles and on lap eleven Alboreto spun at the final corner, meaning Lauda inherited the race lead.
Alboreto returned to the pits for a fix, the Ferrari mechanics tweaked the calipers however it was all for naught and a lap later Alboreto was back in the pits to retire. At this time, Stefan Bellof's impressive debut also came to an end with throttle problems and as did Mauro Baldi's Spirit who had distributor failure.
Lauda and Warwick held a convincing lead whilst Mansell who was some way back in third was being harrowed by Prost's McLaren who led a train of cars including Tambay's Renault, Arnoux's Ferrari, De Angelis's Lotus and Rosberg's Williams. On Lap 19, Nelson Piquet moved up into ninth, passing teammate Teo Fabi. It had been a strong comeback drive from the back of the field by Piquet.
