What it shows
Each constructor carries three season averages:- Car term: the team’s car contribution to lap time from the lap decomposition. Lower = faster car.
- Dirty-air tax: average time lost in dirty air across the team’s measured laps.
- Driver skill: average driver-skill residual across the team’s drivers. This is the driver line-up, not the car.
Teammates are not paired and cross-team pairs are not compared. A cell with no measured reading is blank, not zero.
How to use it
- Select a season from the filter bar; the table reloads.
- Read the car term to rank the cars on the same laps.
- Compare dirty-air tax to see which teams spend more time in traffic.
- Check the driver-skill column to separate line-up strength from car strength.
Data source
The page queriesfct_lap_residuals via DuckDB-Wasm in the browser, using training-eligible laps (ml_eligible), averaged per race and then across the season’s races.
The data window covers 2018–2025.
