The Toleman TG184 was a Formula One racing car designed by Rory Byrne and Pat Symonds and was used by Toleman Motorsport during the majority 1984 Formula One season. The car's potential was evident early on with a second place in only its second grand prix scored by then rookie driver Ayrton Senna in the rain affected Monaco Grand Prix. 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 his legs in practice for the British Grand Prix at Brands Hatch. He recovered and went on to a successful career as a touring car driver.
The TG184 was replaced in 1985 by the TG185.
