Starting her karting career at 9, Martí stepped up to Spanish F4 in 2019, scoring a podium in her debut race with P2. She then switched to W Series in 2021, finishing the season fourth in the Drivers’ Standings as the best-placed rookie and with points in every race that year. The Spaniard’s second season included a maiden pole position in Miami, and she eventually ended the campaign seventh. She will compete with Campos Racing in F1 Academy.
