What every team changed on its car at each race weekend, straight from the filings teams make to the FIA.
In the 2025 season, teams have changed 325 parts on their cars, as declared to the FIA, counting every race weekend through the Abu Dhabi Grand Prix. Red Bull has changed the most (51). The part changed most often is the front wing (47 times). The busiest race weekend was the Australian Grand Prix with 70 parts changed.

Each number is how many parts a team changed for that race weekend. One filing with the FIA can cover several parts, and a bigger number does not mean a faster car. Select a race heading to sort the teams by it (select it again to reverse), or a cell to jump to that team's changes. Swipe the table sideways to see every race.
Racing Bulls changed 1 part. No other team filed anything.
1 part changed.
Pace is each team's best qualifying lap against the middle of the other teams, not pole, so a team on pole can still change. From one race to the next a team's pace moves by about 0.34 percentage points even when it brings no parts (the middle of 118 such weekends this season), so a smaller move says little about the upgrades. Other teams' upgrades and the type of circuit move it too, so these numbers show what pace did, not whether an upgrade worked.
Racing Bulls1 partQualifying pace compared with the other teams: 0.37% ahead at round 22, 0.17% ahead this weekend.
What changed: Gurney option for front flap
Why: An optional gurney has been created for the front wing flap, to provide additional front downforce to suit the balance requirements of the circuit.
FIA Document →Red Bull has changed the most parts in 2025, with 51 across the season. Counts come from the documents each team files with the FIA for every race weekend, and one filing can cover several parts.
Before each race, every team files a Car Presentation Submission with the FIA listing each component it has changed, the reason, how it differs from the previous version, and a short description of how it works. The FIA publishes those documents, and every upgrade on this page links to the one it came from.
Each number is the count of parts a team changed, taken from its filing for that race weekend. One filing can list several parts, and a small tweak counts the same as a big redesign, so a bigger number means more parts changed, not a faster car.
Teams describe each upgrade with set phrases. Local load means changing how hard one area of a part pushes on the air, usually to add downforce. Flow conditioning means shaping a part so the air reaching the parts behind it is cleaner. Drag range, cooling range and balance range are changes that give a team more room to adjust drag, cooling or the car's balance for a circuit. Hover or tap any underlined term on the page for a definition, or see the glossary.
Yes. The search box looks across every part in both seasons, so you can type floor, rear wing, cooling or diffuser and see which team changed it, at which race, and what it was for. Each result links to that race.
Performance upgrades aim to make the car faster everywhere. Circuit specific ones tune the car for one track, such as a low-drag rear wing for Monza or extra cooling for a hot race. Reliability upgrades fix or strengthen a part that has been failing. Teams type the reason themselves, so the page groups their wording into these three types.
A race shows none when every team filed "No updates submitted for this event". In 2025 that happened at São Paulo Grand Prix, Abu Dhabi Grand Prix.
It shows how far the team's best qualifying lap was from the middle of the other teams, as a percentage, at the previous race and at this race weekend. It is measured against the other teams, not pole, so a team on pole can still show a change. It is a number to read, not a verdict: a team's pace moves by a few tenths of a point from one race to the next even when it brings no parts, and other teams' upgrades and the type of circuit move it too, so it cannot say that an upgrade worked.
Not on their own. A filing says what changed, not how much time it gains, and teams often bring parts to test rather than race. The Pace view shows each team's qualifying pace next to the parts it changed, and the Development Tracker shows the season-long trend, but neither can prove that an upgrade caused a change.
