1984 season started on March 25th and concluded on October 21st after sixteen races.
The teams went through several changes, some changed drivers and some their engines, but all were looking to beat the Brabham of Nelson Piquet.
The same Brabham, who kept the Brazilian changed the seat of the #2 car, replacing Riccardo Patrese with the brothers Fabi: Teo and Corrado. This was to allow Teo to compete in the US based Cart World Series too.
Tyrrell, the only team which was presenting itself with a naturally aspired engine for the full season had to substitute his previous drivers, Alboreto and Sullivan with the un-experienced Martin Brundle and with the young promising german Bellof.
Williams kept the same two drivers, which were leveraging the exclusive Honda V6 Turbo engine installed in their machines, tested in the last South African race of 1983.
McLaren, with the TAG-Porsche engine signed Alain Prost and Niki Lauda, an impressive couple, probably one of the strongest of all Formula One history.
Lotus, with a Renault engine, gave the seats to Elio de Angelis and Nigel Mansell, while the same Renault, as team, started the season with the former Ferrari driver Tabay and with the english Derek Warwick.
Toleman, lost Warwick to Renault, presented the Venezuelan Johnny Ceccotto, at that time still motorbike world champion in the class 350, together with the rookie Ayrton Senna, fresh of victory in the British Formula 3 championship.
Alfa Romeo lost major sponsor Marlboro and replacing the red and white was the green and red of Italian clothes manufacturer Benetton, with two fast drivers, Patrese and Eddie Cheever, but the engine was worrying the Alfa supporters, lack of reliability which will be well shown during the season.
Ferrari finally, signed an Italian driver, Michele Alboreto, who will seat alongside the french René Arnoux. Alboreto signature was particularly felt by the tifosi, who were satisfied by Enzo Ferrari choice, although went against his own rules, to don’t have italian driver driving the rossa.
