Which F1 team has brought the most upgrades in 2026?
Red Bull has changed the most parts in 2026, with 52 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.
Where do these upgrades come from?
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.
When are new upgrades added?
Teams file their upgrades with the FIA on the Thursday of a race weekend, so the next round fills in then. This page is updated from those filings, and a race with no filings shows as having no upgrades.
How are the upgrades counted?
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.
What do local load, flow conditioning and the other terms mean?
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.
Can I search for a specific part?
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.
What do Performance, Circuit specific and Reliability mean?
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.
Why does a race show no upgrades?
A race shows none when every team filed "No updates submitted for this event". That has not happened in this season so far.
What does the qualifying pace line on each team's card mean?
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.
Do upgrades mean a team will be faster?
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.
