The Italian Formula 4 Championship is ready to return to the track for the fourth of seven rounds this season and, in doing so, write another page in its history. The Mugello round of the ACI Racing Weekend, scheduled for July 24-26 at the iconic Tuscan circuit, will see the championship reach a new milestone. After attracting 49 entries at Monza for Round 3 last month, the grid has now grown to 50 drivers, setting a new all-time record for the category.
A total of 14 teams will line up on the grid, while the number of nations represented rises to 27. Among the largest entries is US Racing.

He will be joined by Roman Kamyab, Turkish driver Alp Aksoy, China's Kwan Ho Kingsley Zheng and Rome-born Ferrari Driver Academy driver Niccolò Maccagnani. Also representing Formula 1 junior programmes are Christian Costoya (McLaren) and Oleksandr Bondarev (Williams).
