Dallara F3 2025

The Dallara F3 2025 is an open-wheel racing car developed by Italian manufacturer Dallara for use in the FIA Formula 3 Championship, a feeder series for Formula One. The F3 2025 was the second car used by the FIA Formula 3 Championship and was introduced for the 2025 season. As the Formula 3 Championship is a spec series, the F3 2025 is raced by every team and driver competing in the series. The F3 2025 was unveiled at the weekend of the final round of the 2024 season in Monza and later made its first public appearance when teams contesting the 2025 season completed a test day at the Circuit de Barcelona-Catalunya in February 2025.

Design

Engine package

The F3 2025 carries over the same V634, V6 naturally-aspirated engine, developed by Mecachrome Motorsport that powered its predecessors, the GP3/16 and F3 2019.

Tyres

Pirelli would remain as the preferred official tyre partner and supplier of FIA Formula 3 Championship. One change was made to the tyres, as they will now run on 16-inch rims.
