Martí began karting aged nine through her father's rental kart track.[2] Late in her karting career, she was contracted to Fórmula de Campeones in an attempt to step up into professional racing.[3]
Lower formulae
Martí made her single-seater debut in Spanish Formula 4 in 2019, scoring a podium in her first event.[4] A pair of seventh places late in the season would see her finish 16th in the standings and 2nd in the female trophy behind Belén García.[5][6]
Martí would eventually make her W Series debut in 2021. She achieved her first and only podium of the season at the Hungaroring, but finished 4th in the standings—as the best rookie—having scored points in all eight rounds.[10]
Martí was announced as a driver for Campos Racing for the inaugural F1 Academy season.[1] She was disqualified in the first race of the first round at Spielberg, but for the second and third race at the same round she managed a P4 and P5 finish respectively, earning her 15 points and taking her to 8th in the championship standings.
Martí remained in Campos Racing for 2024 with support from Tommy Hilfiger.[13] At the first round at Jeddah in Race 1, Martí was running in fourth but was tagged by Lola Lovinfosse in the final lap and finished in 14th.[14] In Race 2, she finished the race in fourth but was promoted to third after race winner Doriane Pin was given a post-race 20-second time penalty for crossing the finishing line twice.[15][16]
