Senna's first ever Formula One Grand Prix was the 1984 Brazilian Grand Prix held at the Jacarepaguá Circuit in Rio de Janeiro on 25 March. Driving the 1983 car due to the TG184 not being ready, Senna qualified in 17th position (Cecotto qualified 18th). However, Senna's car was the first to retire in the 1984 season, after he was forced to pull out after 8 laps with turbo failure. Cecotto also retired with turbo failure 10 laps later.
