2023 Formula Regional European Championship

[17][18][19] Replacing them were the 2022 Italian F4 and ADAC F4 champion Andrea Kimi Antonelli, Rafael Câmara and third-year FRECA driver Lorenzo Fluxá.

[20][21][22] All three raced for Prema's partner team Mumbai Falcons in the 2023 Formula Regional Middle East Championship, with Antonelli taking the title.

The team signed another second-year driver in Matías Zagazeta, who failed to score points in his rookie year with G4 Racing, to replace Gabriel Bortoleto, who graduated to F3 with Trident.

[24][25] Their lineup was completed by Martinius Stenshorne, who made appearances in four different Formula 4 series in 2022, with a seventh in the Italian Championship as his best result.

[27][28] The team also signed Sauber Academy driver Marcus Amand, who graduated from Formula 4, to replace Esteban Masson.

[29] Van Amersfoort Racing replaced Arden-bound Levente Révész with Niels Koolen, who also competed with the team in the 2023 Formula Regional Middle East Championship.

[34] Levente Révész made the switch from Van Amersfoort Racing to Arden for his second FRECA season, replacing Noel León, who moved across to the Euroformula Open championship.

[37] RPM promoted Irish driver Adam Fitzgerald from the F4 British Championship to replace the Trident-bound Owen Tangavelou.

[43] 2022 French F4 champion Alessandro Giusti made his Formula Regional debut in 2023, joining G4 Racing to replace Zagazeta.

Ferrari Academy driver Maya Weug jumped up to the Formula Regional level after two years in the Italian F4 Championship, replacing Santiago Ramos, who moved to RPM.

[47][48] The seat of Sebastian Ogaard, who moved to the newly created Eurocup-3 series, was originally to be filled by Formula Academy Finland race-winner Iker Oikarinen, before he was replaced by F4 racer Olexander Partyshev.

[58] After Dilano van 't Hoff lost his life in a crash during the second race at Spa, his team MP Motorsport did not enter any of their cars for the following round at Mugello.

At KIC Motorsport, Oleksandr Partyshev missed the round and was replaced by Konsta Lappalainen, who last competed in the series in 2021 and has been driving GT cars since.

[60] Following KIC Motorsport's Oleksandr Partyshev's absence for the round at Mugello, he announced his retirement from racing, citing one of the main reasons to be due to Dilano van 't Hoff's death.

[61] Ahead of the round at Paul Ricard, G4 Racing announced that they would field a third car from that event on for French F4 driver Pierre-Alexandre Provost.

[62] Charlie Wurz and Joshua Dufek, driving for ART Grand Prix and Van Amersfoort Racing respectively, switched to the Euroformula Open prior to round seven at the Red Bull Ring, where both series coincided.

[68] Five drivers were announced to be making their series debut at the penultimate round: Francisco Soldavini for G4 Racing (replacing Michael Belov),[69] Ivan Domingues for Van Amersfoort Racing (replacing Jesse Carrasquedo Jr.),[70] newly crowned French F4 champion Evan Giltaire for ART Grand Prix (occupying the car previously driven by Charlie Wurz),[71] Eurocup-3 driver Javier Sagrera for MP Motorsport (using Bruno del Pino's car)[72] and F3 driver Nikita Bedrin at Monolite Racing to replace Hadrien David.

[73] Saintéloc Racing was another team that changed its lineup as it brought in Lamborghini junior and experienced Formula Regional driver Pierre-Louis Chovet in place of Esteban Masson.

Ahead of the season finale, Monolite Racing announced that Formula 4 driver Valentin Kluss would make his series debut, driving the car previously piloted by Smal, David and Bedrin.

[78] The 2023 Formula Regional European Championship opened at Imola with R-ace GP's Martinius Stenshorne on pole position for the first race.

Haverkort slotted into third, before a red flag was thrown for a crash between MP Motorsport teammates Sami Meguetounif and Dilano van 't Hoff.

Tramnitz' double win allowed him to claim the championship lead by four points over Antonelli, while Stenshorne had a difficult weekend and dropped to fourth.

He kept it through a safety car period, before making a mistake and running off the track to allow Stenshorne back in front and give up the podium to Haverkort and RPM's Santiago Ramos.

Tramnitz then spun around on the penultimate lap, but had his second place ahead of Arden's Joshua Dürksen reinstated when red flags flew shortly after and the race ended prematurely.

A restart with eight minutes remaining after Dürksen and Monolite's Kirill Smal came together gave another opportunity to Antonelli, but Stenshorne prevailed to lead the Italian and Tramnitz home.

Ramos attacked Stenshorne on the final lap, leading to the pair crashing hard into the pitwall while crossing the finish line.

After the race, both Antonelli and Amand were penalized, handing the win to Giusti and allowing Stenshorne and MP's Victor Bernier onto the podium.

Rain hit the Dutch seaside for Sunday, and Marcus Amand took pole position as he judged the changing weather conditions best.

Antonelli needed to outscore Stenshorne by two points to win the championship, and he did so in style: starting in eighth, he utterly dominated the race, claiming the lead after three laps and building a twelve-second gap over Amand despite a red flag mid-race for dangerously wet conditions.

Câmara tried taking the lead in the final part of the race, but Tramnitz' stark defense saw the Brazilian lose ground and concede the podium to Stenshorne and Monolite's guest driver Nikita Bedrin.
