What happened: German Formula 4 set its field at 14 teams for the coming season. The additions include an entry tied to the DTM paddock and one tied to a Formula 1 driver.

Why it matters: A full 14-team field stabilizes the entry list for a core junior development category. Links to established touring-car and Formula 1 operations bring funding, infrastructure and driver pathways.

What to watch: Watch for driver lineups and the calendar release to set testing and race weekends.
