Trained at the school of two wheels, Léna Bühler shone in BMX before turning to go-kart in 2016, and then climbed the ranks in motorsport. Runner-up in the F1 Academy in 2023 with ART Grand Prix, the Swiss driver will this year return to FRECA, where she competed in 2021 and 2022 following a convincing first year in single-seaters in F4 Spain.
