Brazil (1984–1994) against United Kingdom (1980–1995)
Ayrton Senna checks every box: more titles (3 against 1) and superior dominance once scaled to their era (37% of the maximum possible points per season, against 21% for Nigel Mansell). The rest just confirms the gap: Ayrton Senna also leads Nigel Mansell in win rate (25.5% against 16.6%), podium rate (49.7% against 31.6%), pole rate (40.4% against 17.1%), and reliability (37.9% against 49.7% in DNFs). No direct duel possible: they never shared the same garage. To dig further despite the decades between them, the interactive comparison below breaks it down season by season.
