The Toleman TG184 was a Formula One racing car built and raced by the Toleman team in the 1984 Formula One World Championship. It was designed by Rory Byrne and Pat Symonds and powered by a 1.5-liter turbocharged Hart 415T inline-4 engine. The car featured a monocoque chassis constructed from carbon-fiber and aluminum honeycomb, which was relatively advanced for its time.
The Toleman TG184 made its debut at the 1984 Brazilian Grand Prix, where it was driven by Ayrton Senna. Senna, who was a relatively unknown Brazilian driver at the time, made an immediate impression by qualifying the car in seventh place, ahead of many more established drivers and teams. Unfortunately, Senna's race ended prematurely when the car suffered an electrical failure.
Senna's performance in the Toleman TG184 at the 1984 Monaco Grand Prix is perhaps the most famous in the car's history. In wet conditions, Senna drove a remarkable race, overtaking several cars and challenging for the lead. The race was eventually stopped due to heavy rain, and half points were awarded. Senna finished in second place, which remains his best result in Monaco.
Senna continued to impress throughout the 1984 season, with strong performances at several other races, including a fourth-place finish at the Detroit Grand Prix and a sixth-place finish at the British Grand Prix. Despite his impressive results, Senna was unable to secure a victory in the Toleman TG184, but his performances caught the attention of other teams, and he was signed by Lotus for the 1985 season.
The Toleman TG184 was not the most competitive car on the grid in 1984, but it showed flashes of speed and potential. Its performance, combined with Senna's exceptional talent, helped to establish both the car and the driver as ones to watch in the coming years.
