Like its predecessor, the TG183B, the TG184 was powered by the 4 cylinder turbocharged Hart 415T engine which produced approximately 600 bhp (447 kW; 608 PS) in 1984.

This saw Prost win and Senna finish second with only half points given due to the race not going past 50% of the scheduled distance.

[citation needed] Underlying his future as a World Champion, more podiums came for Senna during the 1984 season with 3rd placings at both the British Grand Prix and the season ending Portuguese Grand Prix where Senna also placed 3rd in qualifying, the highest for the car.

Others to drive the TG184 during 1984 were former FIM 350cc and Formula 750 motorcycle World Champion Johnny Cecotto from Venezuela and up and coming F1 drivers Stefan Johansson of Sweden and Pierluigi Martini from Italy.

Unfortunately for Cecotto, the TG184 was his last F1 drive after he badly broke both of his ankles in practice for the British Grand Prix at Brands Hatch.
