The UIM Formula 4 World Championship will return in 2026 with three rounds across Belgium, Lithuania and Italy, featuring new safety regulations including mandatory crash boxes that take effect from 1 January.
The season was due to open at Mons, Belgium on 16-17 May, but the round has been cancelled due to ongoing construction work at the Grand Large race site. The championship now begins at Klaipėda, Lithuania for a combined F2 and F4 event on 5-7 June.
Combined racing with F2
F4 will race alongside the UIM Formula 2 World Championship at two events during the 2026 season. The Klaipėda round marks the first joint event, whilst the second takes place at Viverone, Italy on 7-9 August.
The Viverone weekend will also host the UIM F2 European Championship, creating a multi-championship event featuring both F2 and F4 categories.
European Championship at Aluksne
The UIM F4 European Championship will take place at Aluksne, Latvia on 3-5 July as a standalone event between World Championship rounds two and three.
