Misano World Circuit - The sixth and penultimate ACI Racing Weekend of the season came to an end at Misano. The weekend crowned Luka Sammalisto as the 2026 Italian F4 Champion, while US Racing secured the Teams’ title for the season.

The Italian F4 Championship closed the day at Mugello with a dramatic twist. Race 2 featured the drivers from Groups A and B, with Germany's Elia Weiss (Jenzer Motorsport) starting from pole position. Weiss looked determined to bring Jenzer Motorsport back to victory after the last one came in 2020. However, after controlling the race from the front, the R-ace GP Mercedes Junior Team driver Andy Consani came under increasing pressure, sparking an intense battle. Contact between the two resulted in a puncture for Weiss, forcing the Jenzer driver into the pits. Consani suffered front wing damage but was able to continue, only to later receive a 25-second penalty from Race Control.

Qualifying at Mugello delivered an extraordinary battle for the grids of the opening three races of the fourth round of the Italian F4 Championship. Elia Weiss (Jenzer Motorsport) and David Cosma-Cristofor (Prema Racing) both topped their respective qualifying divisions by setting exactly the same lap time.

Autodromo Nazionale Monza - Luka Sammalisto claimed his third victory of the weekend, the seventh of his season. Once again, it was a perfect score: wins in every race he has taken part in, exactly as he did at Vallelunga.

At the Autodromo Piero Taruffi di Vallelunga, venue of the second round of the Italian F4 Championship, US Racing’s Luka Sammalisto completed a perfect weekend. Three wins from the three races he contested for the Finnish driver, who only missed Race 2 because of the group rotation format, with that race instead won by teammate Edu Robinson.
