The first round of the European KZ Championship in Valencia was a success for Birelart Racing. Pedro Hiltbrand showed total mastery, winning the KZ Final by more than 3.2 seconds, confirming the effectiveness of the development work carried out by Birelart in the run-up to the season. Cristian Bertuca backed up this success by taking 3rd place on the podium and setting the fastest lap of the race. In KZ2, almost a third of the field chose the Birelart chassis, with four drivers in the top 10, including Corentin Rousseau, who finished 6th, among other outstanding results.

On the Wackersdorf circuit, due to a first lap featured by a crash involving several protagonists including Tony Kart driver Tom Leuillet, the Tony Kart Racing Team is unable to go beyond the 5th place finish in the FIA Karting World Championship.

The Tony Kart Racer 401 RR sets the fastest time in the qualifyings of the first round of the FIA Karting European Championship 2023 reserved for KZ and KZ2 categories, however the weekend does not end as expected.

After the four victories in Lonato and Franciacorta, another success has arrived for the Tony Kart Racer 401 RR in the master class of the single-gear karts, on the occasion of the 3^rd round of the WSK Super Master Series. First place also for the Rookie chassis in the MINI Gr.3 U10.

After the two successes at Lonato, their Tony Kart Racer 401 RR also wins in the round 2 of the WSK Super Master Series, staged at the Franciacorta Karting Track, with two victories (in KZ2 and OK) and other pole positions in KZ2 class and in the MINI U10 (with the Rookie model)
