On a rain‑soaked April afternoon in 1985, 24‑year‑old Ayrton Senna turned his Lotus 97T into a precision instrument, seizing his first Grand Prix win at Estoril. He led every lap and finished a minute ahead, despite the race being stopped early due to the two‑hour limit.

Why it matters

Senna’s victory announced the arrival of a driver who would go on to claim 41 wins and three world titles, while also ending Lotus’s six‑year win drought and proving the team could still compete at the front.
