The Tatuus F4-T421 is an open-wheel formula race car designed, developed, and built by the Italian manufacturer Tatuus for Formula 4 junior categories since 2021.

It’s time to release the long-awaited Formula 4 mod for the very same Tatuus T421 car that is bringing such intense and exciting competition to this year’s revived Russian Championship.

As you know, Yaroslav Shevyrtalov (Team Lada) emerged as the top driver of the 2025 season—he also won the title in the Figital Series, where the T421s from SMP Esports had previously been used exclusively. Now, the new car is available to everyone!

The model's physics will still be refined—we simply haven't had time to implement everything we had planned yet. But the virtual F4 is already fully operational, and this is great news for those preparing for the upcoming round of the RAF Interactive Racing Championship, which will take place on November 16.
