Senna's Debut F1 Chassis Auctioned in Monaco for 2.8-3.8M Euros

Ayrton Senna's debut Formula 1 chassis, the Toleman TG183B that carried the Brazilian through his first four races in 1984, will go under the hammer at an auction in Monaco on April 25, with an estimated value of 2.8 million to 3.8 million euros.

The chassis, numbered 05, marks the starting point of Senna's legendary career, which later yielded three world championships before his death in 1994. Senna joined Toleman, a modest team that had entered Formula 1 just three years earlier, after a competitive Formula 3 season against Martin Brundle. The team, often a backmarker, had shown promise by scoring points in the final four races of 1983.

Senna's F1 baptism occurred at the Brazilian Grand Prix in Rio de Janeiro, his home event, where he qualified 16th but retired after eight laps due to a turbo failure. Undeterred, he secured his first championship points in the same car with sixth-place finishes at the South African and Belgian Grands Prix. The chassis also featured in his only failure to qualify during his F1 tenure, at Imola, stemming from a tyre dispute with Pirelli and a fuel pressure issue.
