Who has bought updates to the Azerbaijan Grand Prix? Find out here!

As the 2025 Formula 1 season enters its final stages with just eight races remaining, plenty of focus from many teams is being put into 2026 and the regulation change.

As a result, several teams come to the Baku City Circuit with no updates at all. Championship leaders McLaren, along with Aston Martin, Alpine, Haas, Williams and Sauber, come into this weekend without any updates or modifications.

However, the battle for P2 in the constructors' championship looks to heat up, as Red Bull, Mercedes and Ferrari all make changes from the Italian Grand Prix.

The Scuderia have made circuit-specific changes to the SF-25, with an enlarged front brake duct cooling exit added to the cars of both Charles Leclerc and Lewis Hamilton for this weekend only.

However, for Red Bull and Mercedes, they both make performance changes to their cars, with the changes affecting the local load of the car.

Red Bull have made changes with a re-profiled inboard wing assembly, while Mercedes make their local load change by a redcued chord front wing flap.

Racing Bulls are the only other team that have come into Baku with changes to their car, with both updates to the front and rear of the car affecting its cooling range.
