[2] He won the competition and received help from the French federation from that point onwards; in parallel, Fourmaux began studying to become an orthopedic surgeon at the Lille Faculty of Medicine.

[12] Fourth in Sweden preceded an early crash at the Rally di Roma Capitale in the ERC, though he regrouped to take two further WRC2 runner-up finishes in Estonia and Turkey.

[17][18] Fourmaux then progressed to the World Rally Championship in 2021, driving selected events in a Ford Fiesta WRC and partaking in the WRC-2 class during the remainder of the calendar.

[19] His WRC debut came in Croatia, where a fifth place caused him to be likened to rally legend Sébastien Ogier by team principal Richard Millener.

[23] The season began poorly, as Fourmaux retired from the first three events, experiencing a huge accident in stage three at Monte Carlo and crashing out in a garden in Croatia.

[24][25] Another crash came later in the year at the Ypres Rally; as a consequence of the chassis damage, Fourmaux was not entered in the following two events, while budget issues forced him to miss the season finale in Japan.

[36] At the end of 2023, Fourmaux was recalled to Ford's WRC team to substitute for Pierre-Louis Loubet at the Rally Japan, though he would crash out of the event.

[42][43] Fourth in Latvia and third in Finland came next, as Fourmaux benefited from a late crash for leader Kalle Rovanperä to inherit a spot on the rostrum.
